If you have the type without shims, most dealers sell bucket lifters with different thickness specs. So you can just figure out your clearances and buy the correct thickness bucket lifters and put them in the corresponding positions. Personally I would do this over grinding valve tips.

You are probably imagining "grinding" valves on a bench grinder. That is not what I am referring to. Valves are "ground" or machined when they are made. They are also "ground" whenever they are serviced. To do this you need to use the right equipment - a "valve grinder."

A machine shop owner told me that if I mixed up those buckets and shim, to throw away the engine. All I have to do is to check the shims of the side that was dropped and follow specs. I did tell the owner that I was in a money bind and was fixing head gaskets on a tight budget. smdh! He could have told me that I will spend a couple of extra hours to fix my accidental mistake, not throw away the engine or make it seem like it was impossible. I did not tell him anything, but I thought, how did the manufacturer place those there in the first place? Roll of a dice? So I looked and searched and found this video. I do have the original shop manual to go by with. I am working on a 1998 Subaru Legacy Outback Wagon 2.5L DOHC. I do have to say that regular valve lash adjustment seems easier in comparison.

when you grind the valves you always take the abou the same amount that you grind out between the seat and face say 4 to 5 thousandths for small valves (ground out by lapping), well you grind that same amount off the end of the valve stem them if the lash was working great before (valve job) then you will have the right lash to run again i will mention newly grond valves will seat in over a week or so they will be tighter by 2 thousanths or less if you have to grind off the end of stem in the car tape all the head up with paper and mask tape just leave the ends stick through this keeps metal and grindstone out of the oil areas very bad

Well, that is an absolute helpful video, so huge thanks to explain those different types of bucket lifters (we call them "Tassenstößel" here in Germany, by the way)! I gave you thumps up and an abo. I have low compression on first cylinder with my 2.4 Sonata from 2007, I think it has those unajustable bucket lifters from what I can see by taking the valve cover apart, am I right? I have around 5 Bar Compression whereas the other cylinders do have around 12-13 bar. Head Gasket seems ok (no oil or water mixed up, no pressure in cooling system) So could it just be valve lash to low which causes my compression issue (valve is not closing properly) and would you suggest to measure that before taking all apart and investigate the whole cylinder head? Can I find the specs for this specific engine somewhere on the internet? Can I get this done by myself (grind of the top of the valve I guess this is very delicate material) or is a machineshop needed to do that? I am very much looking forward for your helpful reply!

It could be a lot of things. You are right--you could have too little valve clearance, but that doesn't usually happen all by itself. In order to have too little clearance, your valve or valve seat would have to be worn. You could also have too much clearance, which would be caused by a worn camshaft or a valve that isn't closing all the way due to carbon build up. You also could have a burned valve. This happens when one of your exhaust valves starts leaking, and the hot exhaust gasses leaking past the valve starts to erode the valve until there is a hole in it. You could do a cylinder leakage test to see where the compression leakage is happening. You probably don't have a lab scope, but you could also acquire a compression waveform for that cylinder and compare it to a waveform from a good cylinder to see what is wrong.

@@JustinMillerAutomotive Hey, just to give you an update, I was learning a lot from all of this. I disassembled the Head and as you suggested, a valve was clearly burnt, but it was the smaller one on the intake. Well, I gave the head to the machine shop and as you said, the seats were worn, which I could understand and also clearly see adn feel with my fingers by touching the surface of the seats which was not even anymore, you could feel that quite well with the valves taken apart. So that head was much gone from heavy LPG use. So I went for a used good one, I knew were to look at by now, the seats, valves and everything else looked all ok, flatness of the surface was ok also. I then measured the clearance of the valves that was good for some, not quite so good on others relating to the specs, which for that model (sonata 2.4 Hyundai) are 0.27-0.33 Exhaust, 0.17-0.23 for Intake as far as I can remember. In the buckets themselves there you can read some numbers like 3.100, 3.185 or so, and by changing them from place to place and some logical thinking, I was able to get the clearance all good, even no need to buy new buckets, because they have no adjustable shims or how you call it and are quit expensive. But it was much work, because in order to measure you had to put the camshafts on, and in order to readjust they needed to be removed again. So that was some camshaft on and off I never did before;) (Wheras you did it with the camshafts just put in loose, I decided to torque them to spec everytime measuring. Also, I decided to not go somewhere in between spec of valve clearance, but to go for the highest possible, because I want to use LPG again and I expect the clearance to become smaller over time. Now the head is on and the car is running very smooth, no loud noise from the valves ticking or so, no bad idling as before, full power as far as I can tell and no check engine light on because of a misfiring code. So I learned a lot of things and regarding the valve-section, it started with your helpful video. So thanks again a lot!

I am looking for example of removing springs off deep seated valves, like this. Never knew what the bucket lifters where called before this. Im installing new valve stem seals that I ordered. I see one guy uses socket with magnet inside to grab keepers after bang back of socket centered on spring, with hammer. Looks easy. Im going to use compressed air, I guess 40lbs to keep valves from falling. To remove old stem seals he had washer that fit over with wire tied on to yank out seal. To install spring back on he stuffed Styrofoam from pool noodle in the socket and with socket handle on, pressed spring down, retainers are pushed in place and works. Since valves on my kia rio 1.5L engine are deep seated I know standard valve compressor wont fit. Wondering what your experience is on this? Another thing. I just started taking this apart but do hope I can skip pulling the head. Its a real carbon crusted buggar though. Ive been picking and vacuuming out as much chunks as I can. The dual overhead cams's cover -top bearings section surprised me as the only gaskets I see go around spark plug holes. Apparently no outer edge gasket. I carefully removed carbon crud from the tiny oil passageways and had major blockage on return holes that go back to the pan. So now I wonder, maybe the blockage was so bad that the top of heads where filling up with oil and flooding past seals. But, I will go ahead and do the seals. I coined a term, it needs a carbon-nectomy. ... So Im thinking Id like to drop the oil pan, leave plugs in, and pressure clean the head and hopefully clear out as much carbon as I can and especially force open oil return passageways with high pressure. I have heard other tricks like using kerosene with engine running to warm. Then flush. But this carbon is extra chunky. Scraping out and vacuuming really made a good dent though. When I first took off valve cover I see the rocker splashing oil on far left no. 1 cylinder. This was only cylinder with plug fouling, and engine was giving me the morning blue smoke. I probably only need to change the valve seal on the 1 cylinder. But the engine doesnt loan itself to working on individual components. Just to pull the top section of cams I have to remove timing belt, with all the covers, waterpump, crankshaft pulley, etc. which kinda forces me to buy a new timing belt. That and it does not have individual rockers which would have given me direct access to the problem valve seal, so I am forced to attend to all of them. Now it seems like I should have taken the whole engine out and replaced rings too. Im the original owner and I admit I dogged this engine by lack of oil changes. So now I pay its 2001, standard trans 5 speed and I miss it. Anyway, hope I didnt bend your ear off. Appreciate any info.

Had probs, brought it to Toyota, and they said number 5 was showing valve stuck open slightly. Pulled cams on that side, removed all the buckets. Pellets were kind of stuck to buckets when I pulled them out (oil adhesion). When I removed the bucket in question on #5, the pellet was not stuck to the bottom of the lifter. I found it between the spring and head and had to pick it out. Not sure how that would possibly creep out during regular engine use. Very odd. It *could* have happened when I lifted the bucket out, but all buckets I was able to pull out with fingers except this one that seemed to be depressed more. No signs of wear or metal contact anywhere. Will put them back is and measure lash which previously was like .050 on that stuck valve. I also pushed valve manually. Spring doesn't seem broken, and there was no stickiness to valve as if it had gotten bent. So lost. Don't want to pull head(s). Perplexed. Any words of wisdom?

The clearance will change when the camshaft and caps are fitted and torque to spec
@JustinMillerAutomotive
3 жыл бұрын
That's what you would think . . . but it doesn't change at all as long as your camshafts are resting fully in their bores when you measure. That's why you should only install one lifter at a time--so the other lifters don't raise the camshaft out of its bores. That is also why I hold the cam with my other hand so that I don't accidentally lift the camshaft when I insert a feeler gauge that is thicker than the lash. We do it this way on every engine. I was taught this trick by a machinist who rebuilds hundreds of engines a year. However, I always double-check my measurements once everything is assembled and torqued. By the way, if you torque your camshaft caps multiple times on an aluminum head, you will strip the threads more often. Each time you torque the bolts, the the threads become slightly more fatigued, so I strive to only torque them once!

On some engines, shims of varying thickness are not available and grinding is the only option.

If you try to correct your lash by lapping the valves, you will be there for a very, very long time and will ruin your valves. The obvious solution would be to buy thicker shims. A more painful method might be to grind the valve seats (requires special tools) to get the clearance close to spec, then fine-tune your clearance by grinding the valve tips (requires special tools).

That happens to a lot of people! You can try each lifter in each position until you find the right combination that fits within specification. Some of the lifters may have the exact same clearance as others, so there is likely more than one combination that will work. If you have made changes (ground valves or seats) you will need to adjust the clearance on all of them anyway, so it probably doesn't matter that much any more.

Yes. You can remove the shims while the camshafts are still in. Just make sure the cam lobe is up, then pry down gently on the side of the lifter, while you pop the shim out with a pocket screwdriver or a small pick.

If the valve clearance is not within specification then it could cause low compression, burn a valve, cause a ticking noise, etc. You should always check if you've got it apart. If it is within specification, then you don't need to do anything. Valve clearance changes when the valve or valve seat wears.

It sounds like you have .060 to .010 more clearance than you are supposed to have. I would look for a shim that is in the middle--about 0.040. In theory this should give you clearance of about 0.040, which is right in the center of your spec.

Yes, but if you do it correctly, as stated in the video, you son't have to install and tighten all of the caps and bolts every time you take a measurement and make an adjustment. Installing and removing the bolts that many times will cause the threads in the cylinder head to fatigue, making them more likely to strip.

If you turn the head over and look at the valves, the exhaust valves are USUALLY the smaller valves. if you have turned the head upside down and all of the lifters fell out before you had labeled them, then you will have to check the clearances all one at a time until you get it figured out.

If you have the type without shims, most dealers sell bucket lifters with different thickness specs. So you can just figure out your clearances and buy the correct thickness bucket lifters and put them in the corresponding positions. Personally I would do this over grinding valve tips.

You are probably imagining "grinding" valves on a bench grinder. That is not what I am referring to. Valves are "ground" or machined when they are made. They are also "ground" whenever they are serviced. To do this you need to use the right equipment - a "valve grinder."
Great demonstration! 👍 I’ll be doing this work on my son’s 1997 Camry. Purchased a used long block and will be doing an entire re-ring job for safe measures and showing my boy the ropes on R&R 🚗
Very clear, specific, good clearence and no more doubts. I just cleaned valves lightly near the pitting. Didnt touch the valve contact portion while cleaning but all valves need 0.1 mm more clearence. so will resume my work now. 🙏🏼.. Thanks
great job not too complicated and confused work by many mechanics.
this is a great tutorial, great video and clear explanation.
Great video, litteraly applies to all kinds of cylinder heads. Good job!
Professionally and perfectly explained
On the non adjustable buckets, according to Toyota , service manual , you just go to the dealership parts department, and get them in different thickness to get your desired valve clearance.
Thank you for explaining all the types!!!
Toyota offers different thickness bucket lifters in small increments for their fixed bucket designs. My experience has shown the lash amount usually gets smaller as the engine accumulates wear resulting in the need for a smaller thickness bucket lifter.

A machine shop owner told me that if I mixed up those buckets and shim, to throw away the engine. All I have to do is to check the shims of the side that was dropped and follow specs. I did tell the owner that I was in a money bind and was fixing head gaskets on a tight budget. smdh! He could have told me that I will spend a couple of extra hours to fix my accidental mistake, not throw away the engine or make it seem like it was impossible. I did not tell him anything, but I thought, how did the manufacturer place those there in the first place? Roll of a dice? So I looked and searched and found this video. I do have the original shop manual to go by with. I am working on a 1998 Subaru Legacy Outback Wagon 2.5L DOHC. I do have to say that regular valve lash adjustment seems easier in comparison.
very help info. My Mech told me he was going to be checking the clearance on the valves cause he is getting a misfire on on of the cylinders for my S40. Was wondering how he hoped to adjust the lifters. Now i know he might have mixed them up when he removed them so he has to figure out which one goes where. Thanks.
I HAVE A 03 FOCUS SE, 2.0 DOHC ZETEC VIN-3 & My engine utilizes the solid lifter caps w/out any removable shims, I don't have a chiltons, haines, or any type of book listing any of my tolerances or torque specs! I generally look them up online tho, I NEED MY OWN REFERENCE, I KNOW! MY zetec lifters are noisy & I have done all the work myself! tho, I did remove my camshafts & considered the gap & replacing my lifter caps! I installed new timing components & water pump & new main & rod bearings. lastly was when I put my motor back together did I consider the gap between my lifter & buckets. I need to look into their gap specs & replacing them because they are noisy & w/200k miles, I am sure there could be some deviation! wish you were specifically working on a 99-04 American, 1st gen focus.

Great video, Thank you!
when you grind the valves you always take the abou the same amount that you grind out between the seat and face say 4 to 5 thousandths for small valves (ground out by lapping), well you grind that same amount off the end of the valve stem them if the lash was working great before (valve job) then you will have the right lash to run again i will mention newly grond valves will seat in over a week or so they will be tighter by 2 thousanths or less if you have to grind off the end of stem in the car tape all the head up with paper and mask tape just leave the ends stick through this keeps metal and grindstone out of the oil areas very bad

Well, that is an absolute helpful video, so huge thanks to explain those different types of bucket lifters (we call them "Tassenstößel" here in Germany, by the way)! I gave you thumps up and an abo. I have low compression on first cylinder with my 2.4 Sonata from 2007, I think it has those unajustable bucket lifters from what I can see by taking the valve cover apart, am I right? I have around 5 Bar Compression whereas the other cylinders do have around 12-13 bar. Head Gasket seems ok (no oil or water mixed up, no pressure in cooling system) So could it just be valve lash to low which causes my compression issue (valve is not closing properly) and would you suggest to measure that before taking all apart and investigate the whole cylinder head? Can I find the specs for this specific engine somewhere on the internet? Can I get this done by myself (grind of the top of the valve I guess this is very delicate material) or is a machineshop needed to do that? I am very much looking forward for your helpful reply!

It could be a lot of things. You are right--you could have too little valve clearance, but that doesn't usually happen all by itself. In order to have too little clearance, your valve or valve seat would have to be worn. You could also have too much clearance, which would be caused by a worn camshaft or a valve that isn't closing all the way due to carbon build up. You also could have a burned valve. This happens when one of your exhaust valves starts leaking, and the hot exhaust gasses leaking past the valve starts to erode the valve until there is a hole in it. You could do a cylinder leakage test to see where the compression leakage is happening. You probably don't have a lab scope, but you could also acquire a compression waveform for that cylinder and compare it to a waveform from a good cylinder to see what is wrong.

@@JustinMillerAutomotive Hey, just to give you an update, I was learning a lot from all of this. I disassembled the Head and as you suggested, a valve was clearly burnt, but it was the smaller one on the intake. Well, I gave the head to the machine shop and as you said, the seats were worn, which I could understand and also clearly see adn feel with my fingers by touching the surface of the seats which was not even anymore, you could feel that quite well with the valves taken apart. So that head was much gone from heavy LPG use. So I went for a used good one, I knew were to look at by now, the seats, valves and everything else looked all ok, flatness of the surface was ok also. I then measured the clearance of the valves that was good for some, not quite so good on others relating to the specs, which for that model (sonata 2.4 Hyundai) are 0.27-0.33 Exhaust, 0.17-0.23 for Intake as far as I can remember. In the buckets themselves there you can read some numbers like 3.100, 3.185 or so, and by changing them from place to place and some logical thinking, I was able to get the clearance all good, even no need to buy new buckets, because they have no adjustable shims or how you call it and are quit expensive. But it was much work, because in order to measure you had to put the camshafts on, and in order to readjust they needed to be removed again. So that was some camshaft on and off I never did before;) (Wheras you did it with the camshafts just put in loose, I decided to torque them to spec everytime measuring. Also, I decided to not go somewhere in between spec of valve clearance, but to go for the highest possible, because I want to use LPG again and I expect the clearance to become smaller over time. Now the head is on and the car is running very smooth, no loud noise from the valves ticking or so, no bad idling as before, full power as far as I can tell and no check engine light on because of a misfiring code. So I learned a lot of things and regarding the valve-section, it started with your helpful video. So thanks again a lot!

So if my engine is 16v it will have 16 shims??
I am looking for example of removing springs off deep seated valves, like this. Never knew what the bucket lifters where called before this. Im installing new valve stem seals that I ordered. I see one guy uses socket with magnet inside to grab keepers after bang back of socket centered on spring, with hammer. Looks easy. Im going to use compressed air, I guess 40lbs to keep valves from falling. To remove old stem seals he had washer that fit over with wire tied on to yank out seal. To install spring back on he stuffed Styrofoam from pool noodle in the socket and with socket handle on, pressed spring down, retainers are pushed in place and works. Since valves on my kia rio 1.5L engine are deep seated I know standard valve compressor wont fit. Wondering what your experience is on this? Another thing. I just started taking this apart but do hope I can skip pulling the head. Its a real carbon crusted buggar though. Ive been picking and vacuuming out as much chunks as I can. The dual overhead cams's cover -top bearings section surprised me as the only gaskets I see go around spark plug holes. Apparently no outer edge gasket. I carefully removed carbon crud from the tiny oil passageways and had major blockage on return holes that go back to the pan. So now I wonder, maybe the blockage was so bad that the top of heads where filling up with oil and flooding past seals. But, I will go ahead and do the seals. I coined a term, it needs a carbon-nectomy. ... So Im thinking Id like to drop the oil pan, leave plugs in, and pressure clean the head and hopefully clear out as much carbon as I can and especially force open oil return passageways with high pressure. I have heard other tricks like using kerosene with engine running to warm. Then flush. But this carbon is extra chunky. Scraping out and vacuuming really made a good dent though. When I first took off valve cover I see the rocker splashing oil on far left no. 1 cylinder. This was only cylinder with plug fouling, and engine was giving me the morning blue smoke. I probably only need to change the valve seal on the 1 cylinder. But the engine doesnt loan itself to working on individual components. Just to pull the top section of cams I have to remove timing belt, with all the covers, waterpump, crankshaft pulley, etc. which kinda forces me to buy a new timing belt. That and it does not have individual rockers which would have given me direct access to the problem valve seal, so I am forced to attend to all of them. Now it seems like I should have taken the whole engine out and replaced rings too. Im the original owner and I admit I dogged this engine by lack of oil changes. So now I pay its 2001, standard trans 5 speed and I miss it. Anyway, hope I didnt bend your ear off. Appreciate any info.

Had probs, brought it to Toyota, and they said number 5 was showing valve stuck open slightly. Pulled cams on that side, removed all the buckets. Pellets were kind of stuck to buckets when I pulled them out (oil adhesion). When I removed the bucket in question on #5, the pellet was not stuck to the bottom of the lifter. I found it between the spring and head and had to pick it out. Not sure how that would possibly creep out during regular engine use. Very odd. It *could* have happened when I lifted the bucket out, but all buckets I was able to pull out with fingers except this one that seemed to be depressed more. No signs of wear or metal contact anywhere. Will put them back is and measure lash which previously was like .050 on that stuck valve. I also pushed valve manually. Spring doesn't seem broken, and there was no stickiness to valve as if it had gotten bent. So lost. Don't want to pull head(s). Perplexed. Any words of wisdom?

The clearance will change when the camshaft and caps are fitted and torque to spec
@JustinMillerAutomotive
3 жыл бұрын
That's what you would think . . . but it doesn't change at all as long as your camshafts are resting fully in their bores when you measure. That's why you should only install one lifter at a time--so the other lifters don't raise the camshaft out of its bores. That is also why I hold the cam with my other hand so that I don't accidentally lift the camshaft when I insert a feeler gauge that is thicker than the lash. We do it this way on every engine. I was taught this trick by a machinist who rebuilds hundreds of engines a year. However, I always double-check my measurements once everything is assembled and torqued. By the way, if you torque your camshaft caps multiple times on an aluminum head, you will strip the threads more often. Each time you torque the bolts, the the threads become slightly more fatigued, so I strive to only torque them once!

If the head is already off and you have a valve grinder, it could be a lot quicker and less expensive to grind the valve tips! On some engines, shims of varying thickness are not available and grinding is the only option.

If you try to correct your lash by lapping the valves, you will be there for a very, very long time and will ruin your valves. The obvious solution would be to buy thicker shims. A more painful method might be to grind the valve seats (requires special tools) to get the clearance close to spec, then fine-tune your clearance by grinding the valve tips (requires special tools).

Don't grind the bucket. However, if you have shim that is removable from the bucket, you can grind the bottom of the shim, where the hardened surface doesn't matter. If you grind the tip of the valve stem, you should never take off more than 0.020". To be honest, you generally shouldn't need to ever grind more than 0.001"-0.003" from the tip.

That happens to a lot of people! You can try each lifter in each position until you find the right combination that fits within specification. Some of the lifters may have the exact same clearance as others, so there is likely more than one combination that will work. If you have made changes (ground valves or seats) you will need to adjust the clearance on all of them anyway, so it probably doesn't matter that much any more.

I have a 2001 Mazda 626 2.0 with solid bucket lifters. I replaced the valve seals now I’m ready for testing the valve lash. Would you recommend replacing with hydraulic valves?

I am assuming that you are asking if you should replace your solid lifters with hydraulic lifters? If so, I would not do that. First, I don't think you can find replacements for your engine. Second, there is probably nothing wrong with the lifters you have.

I know now that I can’t replace the solids with hydraulic. Just asking. I have bad valve ticking. I don’t know where I can find different size shims? Any suggestions?
so im trying to find out the specs for a zj8 does anybody know what the clearance is for a xj8?????
Is it possible not to remove the cylinder head when replacing the shims on a Toyota vehicle?

Yes. You can remove the shims while the camshafts are still in. Just make sure the cam lobe is up, then pry down gently on the side of the lifter, while you pop the shim out with a pocket screwdriver or a small pick.
Can hydraulic bucket lifters be used in place of the non shim and shim style buckets lifters?

No. The lifters are made specifically for the engine, they are usually not interchangeable.

Is it necessary? I have got solid one's in my car and it runs beautiful do I still need check the clearance?

If the valve clearance is not within specification then it could cause low compression, burn a valve, cause a ticking noise, etc. You should always check if you've got it apart. If it is within specification, then you don't need to do anything. Valve clearance changes when the valve or valve seat wears.

Can I replace the shim lifters with hydraulic lifters?

No, you generally have to replace the lifters with the ones that are designed for that engine only.
I have a car I’m working on the spec is between 0.020m to 0.061 I’m getting .0120 on my gauge how do I know what size shim I need ?

It sounds like you have .060 to .010 more clearance than you are supposed to have. I would look for a shim that is in the middle--about 0.040. In theory this should give you clearance of about 0.040, which is right in the center of your spec.
Does anyone have the order, or at least the specs for the 1GRFE 4.0 V6, more specifically a 2004 4runner? I lost my footing and a few of the valve tappets fell out and I don’t know where they go, lol. Any help is appreciated!!

According to Toyota FSM for your specific model/year the intake valve clearance 0.006 - 0.010 inch and for Exhaust 0.011 - 0.015
i thought you were supposed to put th cams on and then check clearance

Yes, but if you do it correctly, as stated in the video, you son't have to install and tighten all of the caps and bolts every time you take a measurement and make an adjustment. Installing and removing the bolts that many times will cause the threads in the cylinder head to fatigue, making them more likely to strip.
Is that 240sx head cylinder?

Hello, how do I know which lifter belongs to intake and exhaust? Since I already opened all of them, how can I find which one belongs with which? Thank you very much.

If you turn the head over and look at the valves, the exhaust valves are USUALLY the smaller valves. if you have turned the head upside down and all of the lifters fell out before you had labeled them, then you will have to check the clearances all one at a time until you get it figured out.

Whats the tool name
so I used the wrong weight oil and 10w vs 5w and got alot of valve noise,, I'm guessing I have Hydraulic. going to have to sacrifice the recnt oil change
Very helpful explanations but very stupid design .
Bucket lifters are a horrible design…
