Your videos are awesome.. I'm in Australia and I've got the 1998 vzj95r 90 series Prado with the 5VZ-FE motor and 5 speed manual which is basically in almost every way the same vehicle as the 3rd gen 4runner you've got and we have very few people doing content on working on them and nobody doing content so in depth!! Your channel has single handedly step by step walked me through pulling apart and maintenance of almost every mechanical part of my Prado and for that I thank you sir! Amazing help and good clear and detailed step by step content on keeping these good old rigs on the road safely and confidently learning how to do things so I can repair, replace and maintain things when I'm on road trips and 4wd trips in remote locations!

I used straight feeler gauges for my 5VZ-FE, but would have preferred the 45 degree feeler gauges as used in your video. I found it essential to dismantle the feeler gauge set and handle the blades individually. I made a feeler gauge rack using a piece of cardboard, slicing into the cardboard with a razor blade every few inches and labeling each slot with the name of the gauge destined for that particular slot. This made handling and reading the gauges most efficient.

@TimmyTheToolman

Good technique with the cardboard.

Just went through this ordeal, with the engine on a stand, last week, without the special tool. I learned the hard way about turning the cam with a shim out. I escaped my predicament by using a thicker feeler gauge as a ramp and gritting my teeth just the right way. Pulling out the exhaust cams is absolutely a great shortcut - Be sure to bolt the split gears in place before you remove or you'll be very unhappy. Be sure to remove the bolt or you will be even more unhappy. I wish I could make a video to show my "no special tool" hack. I simply cut some 1/16" thick aluminum into a square at approx. 1-1/2" square. I nipped the corners to create a somewhat lopsided octagon. I then drilled a 1" hole through it using a step bit. (This is backwards - i actually drilled the hole FIRST then cut it into a 1-12" octagon). Lastly I cut the octagon with a hole through in half. Then I simply rotated the engine until the cam depressed the lifters and snaked the aluminum piece in to hold the bucket down.This worked really well, sometimes, and sometimes it didn't work too good at all, depending on which lifter I was working on. Raiding the local pick-your-part yielded all but one of the shims I needed. It also got me a few extra shims, one of which I spent two hours carefully sanding .002 of material off of. All in all it was a very harrowing procedure but it can be done.

Thanks for your videos on adjusting valve clearances. Gave me the courage to do my 3RZ-FE myself. I had a lot more luck with the Schley tool when I took it apart and only used the bottom piece. Made the profile narrower and pushed the valve shim/bucket down further, so it was much easier to use the hold-down tool. It was easier to see what I was doing and gave me more options on where the tool could be used.

Thanks for the nice compliment. We appreciate it. This is what I've told lots of people. The best person to work on your vehicle is yourself because you're not in a hurry like lots of mechanics are because they work under a flat rate system, and unlike you, they don't have a vested interest in your vehicle like you do. Professional mechanics makes lots of mistakes. Sometimes they are honest about them but sometimes not and you don't realize their screw-up until one day you're tearing into your engine or other part of your rig and realize what they did like strip a bolt or nut or you find missing bolts and nuts. Sometimes they flat out botch a job and they still aren't honest about it and then let you return and have to fight to get them to fix it or give you your money back. When I work on my rigs or other people's rigs, I take my time and I'm not in a hurry. I want to make sure the job is done right the first time. So with that said, I'm not a fast mechanic because of how meticulous I can be and that means I probably wouldn't be a mechanic that would make a lot of money under a flat rate system or make more money for the shop I was working for if I was paid hourly. This is big reason why Sean and I do what we do. We want to empower people to do their own work because we believe for the most part, people are better off doing their own work because they are going to make sure it's done right.

@@steelriggins2101 The numbers would have been higher at operating temp but those low cylinders wouldn't have come up over 100 psi, because the engine was warm. The fact a couple of the cylinders were pretty high, 180 & 195. shows me the difference between cold and warm isn't a huge difference. Also, those two cylinders that had the highest values both needed their exhaust valves adjusted so the reason they came up into the 200's could have been partially from the valve adjustment and not just from the warming up of the engine.

In the past, on many Toyotas I’ve had it where the bucket itself actually wears out underneath where it contacts the top of the valve, leaving an almost imperceptible circular impression. Shims on top won’t fix this because they don’t make one small enough to compensate and that isn’t where the noise is coming from, it’s noise from the top of the valve stem to the bottom of the bucket where it’s worn. You replace the whole bucket to fix. Best practice I’ve found is replacing the bucket on valves out of spec and then re-measure to see if the clearance tightens up to in range.

@@CharlieCiampa The bucket just lifts out. We show it in the video.

So after watching I’m thinking and using some knowledge from reciprocating aircraft engines: 1) valve stems stretch over time due to creep, especially exhaust valves which are subject to heat - the valve stems elongate => gap closes up. This affects valve timing/overlap and volumetric efficiency. A leaking exhaust valve will cause a higher exhaust manifold temp as the gas is combusting in the manifold in lieu of inside the cylinder. 2) measuring components - a film of oil on a part (or variation in the film) yields different measurement answers. The cam in the journals may be positioned differently based on differences in the film thickness, similar for under the bucket / valve stem and between the shim and cam lobe. Aircraft oil is typically 50 weight so this is more pronounced but still a factor I think. 3) totally hindsight - I would disturb as little as possible - namely not remove the cam and the bucket either, leave the hold tool in place, remove and measure the shim and replace it (same shim) then on to the next one until they are all done. This would reduce measurement variability. Admittedly, I would take a week to do this waiting on parts. Then I would do my calculations and repeat the cycle replacing them all as needed. (Yes a stock on hand of shims would be preferable and reduce this timeframe). This isn’t my only daily driver, so I can. 4) it would be educational to see all the values and ‘shim moves’ that occurred. 5) hindsight again: I will do a warm before and after compression check. It looked like the tape was covering the intake during the compression test, I think I would remove it, but I would clean the engine to preclude the dust being ingested. Just some thoughts from an interested party. I may be doing this soon.

However, I did recently have a major expensive repair I was unable to diagnose and hence am about to foot a thousand dollar mechanic bill for a drive shaft replacement. Do you have any "maintenance must do" type of videos? Critical stuff that someone with a higher mileage 4runner should look out for and inspect to prevent such a type of situation (for example, I didn't know to grease the driveshaft every 5k miles). Plus I didn't have the lifts and big tools to do the job, and it was already at the mechanic so I felt pressured to accept their work, not knowing if they'd retaliate and sabotage my rig if I declined.

It's hard for us to point you in the right direction when so much work has been done to the engine. The only advice I can give you is recheck all your electrical connections and make sure you didn't forget to plug something in, like the crank position sensor or cam position sensor. Make sure your spark plug wiring is correct, etc, etc.

A quality rebuilt engine will cost you a lot of coin. Doing the valve cover job is easy and affordable. The rear main seal job requires the removal of the transmission but we have videos for that as well. But, your rear main seal might not be leaking. Oil traveling down from leaking valve covers can make quite a mess. Do the valve cover gasket job, check and adjust your valve clearances while you're in there and then clean up the underside of your rig really well and then monitor for leaks. Even if the rear main seal is leaking, it would have to be a big leak to motivate me to pull the transmission. Oil is affordable and if you're willing to deal with a little mess, a small oil leak is nothing to lose sleep over. My two cents.

Not much in the way of symptoms. If a valve gets too tight, you'll burn a hole in it so you should check the clearances at some point for peace of mind.

My Rav4 ticking badly. How much out of tolerance (in millimeter) should I be concerned? Few buckets barely out of tolerance.

@TimmyTheToolman

We measure in thousands, not millimeters for the purpose of this job. Any valve out of spec is a concern, but mainly when the value is on the low end. A valve without enough clearance won't close all the way and can end up getting a hole burned into the side of it.

I know that valve adjustments are supposed to be done at certain intervals, is there a way to know when this needs to be done without taking the VCs off? Valve tick, loss of power, no starts?? I haven't owned my T4R for very long and the car has high mileage. Previous owner just did VC gaskets also so I don't want to go in.

Valves making extra clatter could be an indicator, but valve clearances usually tighten and not loosen so I don't know if valve train noise is the best indicator. Definitely loss of power or a misfire could lead you down the road to needing a valve adjustment. I don't know if Toyota has a recommended interval to check the valve clearances on this engine. My 2000 3rd Gen hasn't had a valve adjustment yet and it has 215k miles but I plan on doing it soon. I think every 100k miles would be a good interval for this 5VZ-FE engine. Other engines like the 4 cylinder 3RZ are more known to have valves to be out of spec and should be checked more frequently like every 50k. If you have over 200k, I think it would be prudent to check the valve clearances. From what I saw on Wei's engine, I'm a little concerned about what I'm going to find with my 2000, but I did do a compression check of my 2000 engine 3 years ago when it had 170k miles and my compression numbers were pretty good. .

Just a point of reference, the interval for my 2000 Tacoma is every 30,000 miles or 24 months. Maybe when I read “valve clearance check” it might have seemed out of my skill level, so possibly that’s the reason I have never done that job on any of our vehicles. I know me bad, but from what you said about how commercial shops don’t want that kind of business, it isn’t any wonder. That’s a shame because you and Wei have, in this video, PROVED that bad engine performance (poor compression) can be almost completely corrected by a good valve adjustment being done. At the point you did the initial compression check, I was thinking OVERHAUL, only to take it all back by the end of the video. By then I was amazed, and realized the importance of doing that part of the suggested maintenance.

Amazing video.

I'm having a hard time dislodging the shims. They seem to be fused with the bucket. When the bucket is down the shim stays down with it so that I can't get underneath the shim with a pick. Any suggestions? Removing the camshaft for one or two shims seems crazy.

@TimmyTheToolman

With the bucket compressed, can you spin the shim? If you can, that means you have the bucket compressed enough. If you can't spin the shim, you don't have it compressed enough and that's why it's fighting you. If the shim spins, you just need to use more force against the shim with a pick tool while giving force upwards to dislodge it. Another trick you can try is try blasting shop air under the shim to dislodge it. If the shim doesn't spin, you might want to get a buddy to help you. One of you presses down the bucket with a flat blade screwdriver while the other guy either uses a pick tool or shop air nozzle to get the shim out. You'll get it. It's frustrating.

@TimmyTheToolman

6 ай бұрын

I usually measure a few times in different areas to get an average on the shim thickness. The shims and cam lobes can wear. When we measure shims, they quite often fall between sizes you can purchase from Toyota because of the wear. You measure, do your calculations, install the shim that's closest to the size you need, and then recheck the valve clearance. Sometimes, you can't get it exactly where you want it because of the shim sizes available. You get it within the spec the best you can and call it good.

175 psi is the minimum suggested compression from what I remember. Did you perform the compression test with the engine warm? Yes, I think checking the valve clearances is a good next step. I would only pull the head if you have signs of a head gasket failure or a cracked head. As long as the rig runs decent, don't worry about the low compression numbers even if you can't get them up after the valve adjustment. Wait until you have a more serious issue to pour big time and money into it.

Ok I got the supercharger bolted correctly, replaced the plugs with Denso IK22's, switched to a 170 degree thermostat, switched over to min 91 octane fuel, etc. Ok so I bought a brand new throttle body with everything included. My problem as you already know is my 96 has a 4 wire TPS and the 97 has the 3 pin TPS. I was able to find a new 3 wire custom harness with 3 long blue wires coming off the new connector. I could really use your advice on how to correctly wire up this new 3 wire TPS into the correct wires under the hood and whatever I need to do inside with newer 97 ECU wiring. Or will it work correctly if I were to leave it alone and not switch out the throttle bodies and tps. Just leave it running the 4 wire set up. I understand that the extra wire on the 96 is for the idle or something? And the newer 97 3 wire is 100% controlled by the ECU? How is that going to affect running with the Supercharger as far as the 3 vs 4 wire TPS? Anyways thank you so much in advance for any help! Scott!

When you look at the factory service manual, it has shim thicknesses and labels them with simple digits i.e “7”, “8”, “9” etc. brand new shims will have measurements that coincide with the numbering system of shims so you know what to order from the dealer, But the shims we have the .5 numbering on were used shims and weren’t a true 8 or 9, hence that 1/2 number… hope that makes sense. - Sean

When you do it is personal preference. I would suggest doing it if it's never been done and you have 200+k miles on your engine. The reason you do it, is because keeping the valve clearances within spec can improve the engine performance and prevent an expensive failure. Valve clearances usually tighten because the valves and valve seats wear over time. A valve that gets too tight of a clearance won't close all the way and the result is a hole gets burned into the side of it. Start watching this video we made at play time 10 minutes and 5 seconds for an explanation of how a tight valve can get damaged. kzread.info/dash/bejne/pHqEqtR6g9WphbA.htmlsi=NHoj7E339nNeDPuu

That’s one of the best KZread DIY videos on auto maintenance I have ever watched, and I have spent a LOT of time watching, ever since I decided to do my own auto repair. That was many years ago, when I had a bad MT clutch replaced on my 1994 Celica at a local shop. My wife had collided the right front tire with a curb. She didn’t tell me, and later on when I was driving I heard a strange noise. I pulled up the hood and saw the right engine mount had broken and that side of the engine was hanging down about two inches. Two bolts that were pushed through from the top of the mount did not have nuts, no nuts at all, I thought because it would have been a little hard for the guy to reach underneath to put the nuts back on. Only one bolt was holding the engine in place. Since I began doing all my own auto maintenance, I have seen many things done improperly by jack-leg “mechanics” who charge for their services. Everything you said in justifying your own decision to DIY is absolutely correct. So, in doing my “due diligence” before doing the valve adjustment on my 2000 Tacoma 2.4L 2RZ-FE 2WD pickup, I looked around for info on doing the job and discovered your excellent video. I learned so much from that video. I had begun by chasing an oil leak, and traced it to the (one valve cover gasket). When that was popped, I was faced with a horrible oil sludge problem. So I started cleaning by using brake cleaner on the inside of the valve cover, installed new spark plug gaskets, checked the PVC valve, placed a new gasket on it and set it aside. Went at the camshafts with diesel fuel as a solvent, trying not to use anything that might damage the engine internals, planning to go to the engine bottom, remove the sump and clean everything there with brake cleaner. That left me with deciding what to do with the sludge internal to the engine. Thinking BG EPR, but am trying to be cautious. While the valve cover was off, I thought I might take the opportunity to check the valve clearances, and that brought me to your video where I learned that taking the exhaust camshaft out isn’t all that hard, so my next step is just that, to see how much more gunk I can remove before doing the clearance checks. The two links you provided for the valve tools show “out of stock.” So, I am still on the hunt for those tools. The Toyota SST you showed is $178 (or so), which is out of my reach, so it’s ok its not available. The other tool is about $70 with shipping, also pricy. Guess I can’t complain, given the rampant inflation and supply chain disruption. I don’t know you personally, but do hope you will continue producing such excellent DIY auto maintenance videos, and hope you do well with them.

Yes, the right tools can make all the difference.

Hey Tim, would you consider it a "go" or "no go" if it goes but with slight/moderate resistance?

If you can get it to slide under the cam lobe, it's a go. It's just on the verge of a no-go. So, for instance, if a .008 feeler gauge went in tight, it's probably somewhere between a .0075 - .008. This is an example of why doing a valve adjustment is a test of patience. You can do the measurements and calculations, put in the shim you think you should to get you to the target spec and it doesn't work out. Sometimes, you get close, and that's all you can do. You are limited by the shim sizes available. Sometimes you can dial the spec in perfectly, other times, it's a compromise. I suggest always compromising to a higher spec than a lower spec. Valves that are at the upper part of the spec don't cause issues. Valves that are too tight and don't close all the way can burn up.

@@TimmyTheToolman thanks that makes sense! One more question, at what clearance did you decide the shims should be changed? All of mine are within the safe range but one is only .02 mm over the minimum and several are about .03-.04 over. Thanks!

@leomullen6273 Anything out of spec or at the far ends of the spec I decided to change. Maybe I should have left the ones alone at the upper ends of the spec, but I decided to try to bring most of them back towards the middle of the spec. Kind of personal preference.

Hows its going tim, kind of confused at the end of the video. You stated it didn't work out in the beginning and the numbers weren't coming in as expected. So then Wade i believe is his name, opened it back up to correct it & got the valve lash specs as close as possible? which prompted the better compression test results? Did you guys not have the valve lash specs in range on the first time around? Was having a warmed up engine a factor of better results, than the first check with a cold engine? Great vid. thanks

The valve lash can be tricky. You measure the lash, make you calculations, put in the right thickness shim, re-measure and find your it didn't bring the lash to where you thought it would. I just did this job on my 2000 4runner and I had a sort of similar experience. Sometimes the new shim brought the lash exactly where you wanted it and other times not. I even cycled the bucket down and up many times to make sure the shim was fully seated in the bucket. My buddy's name is Wei. He finally got the valve lash close enough and called it day. The end result is his compression numbers improved. The warmed up engine can be a factor, but it wouldn't make up for a massive number difference like we saw. His issue was the valves not closing all the way due to the valve lash tightening over time.

@@TimmyTheToolman were there any new tips you had apart from what’s in the video after doing the job a second time on your vehicle? Wondering if you ended up having lots out of spec on your vehicle like Wei’s. Did you pull exhaust cams? And did you use the Toyota tool instead of the aftermarket one & was it worth the extra $$? When I do this job I’m going to call my local Toyota dealer and see if they’ll tolerate me ordering loads of shims only to use the ones I need and return the rest.

@andrew-online When I did my valve adjustment, I had way fewer valves that needed adjusting. Some that I adjusted were in spec, but at the edge of the spec, so I brought them to closer to the middle of the spec. The genuine Toyota tools worked out well. I didn't use the aftermarket ones. But, even with the Toyota tools, it's still not a fun job. It's a back breaker leaning over the engine for a long time. I suggest taking lots or breaks.

Great job, and info. You explained very throughly! 👍💪🇺🇸

Thanks Ken. We appreciate the compliment.

Isn't there a mistake in the calculation for the size of the new shim at 34:20 he subtracted instead of adding or is my math wrong?

@TimmyTheToolman

Anything is possible. We got to a point that we were exhausted making this video. If your math didn't jive with ours, we probably made a mistake. It happens.

The reason for the zero clearance is because of the wear on the valve face and seat . It’s very easy to change the valve to regain your clearance on a lobe that has zero, after which you can resort to juggling the shim that would give you the desired (recommended) clearance

Well, you have to remove the head which is a fair amount of extra work so there's that. So, I wouldn't say it's easy. Is what you're saying true? Sure. But, if I'm going to pull the head, I'd may as well rebuild the whole thing. And, if you're going to rebuild one head, you may as do the other one.

The cam marks at 7:39 are useful. But... those are really cam phasing marks, and an incorrect belt arrangement [being off a tooth or whatever] could find cams phased at some unknown piston position. If this is screwed up, it probably happened with the last timing belt change or water pump replacement.

Yep, a timing belt improperly installed will throw off the timing.
