If it is AFM equiped and actually has a Collapsed/stuck AFM lifter. That is a direct injection engine though so it has a lot of extra things to consider beyond just the lifter. The Direct injection engines after 2014 are prone to other issues such as: -Bent pushrod from factory interference with hole in head and/or spring on AFM lifter, or internal lifter failure/blowout that caused it to bind/wedge. (This has the same symptom as a collapsed lifter in many cases) -Chewed up cam lobe and lifter roller. This is caused by the soft metal the newer cam is made of and I recommend a full AFM delete at this point. The symptom from this is a light ticking in most cases. -Collapsed AFM lifter. This happens on the direct injection engines usually because the VLOM is leaking pressure into the oil towers when it shouldn't. The VLOM mod I do it pretty much needed on these models. I have a video exclusive just for this VLOM unit kzread.info/dash/bejne/qKuYq7B-o9y_fJc.html -Broken timing chain tensioner. Not that common but worth a mention One last thing to note is on DFM. In 2019-2021 they started to implement a system called DFM. The DFM or Direct Fuel Management controls all 8 cylinders instead of only 4 like AFM does. This system to my knowledge wont allow my products to work with it. It has 8 separate solenoids bolted into the block instead of 4 solenoids in a VLOM assembly. It still functions the same but with twice the AFM lifters. It's still unclear as to the reliability of these but I do know they still bend pushrods occasionally. If anyone reads this within driving range of southern South Dakota with one needing service, I would love to crack it open and will give a discount to the first one I get a chance to work on.

Got an ‘08 Silverado with a sticky lifter. Really stuck the other day so I had to pull the valve cover off and have someone crank the starter while tapping on the lifter side of the rocker arm. Popped pretty easily. Waiting on an HP Tuners unit so I can disable it totally.

I purchased that release tool, and it worked!! Thanks!

Great video! And I subscribed to your channel. Thank you for helping so many people.

Exactly what mine is doing now, no CEL or misfires. It still runs decently but a bit sluggish.

i had a 350 with a cylinder #8 exhaust side sticky lifter. same sound and everything. i ended up giving it a little load and went up hill and threw it in 5th and had it bog. worked like a charm

Great video and very smart of you to come up with a tool for helping with this issue. I have a 2013 Suburban with 110k on it and no problems yet. A couple of years ago I bought a module that plugs into the OBD port and shuts off the AFM system. Would this take the place of the tuning that you mention? Also if I am not currently experiencing a problem, what might I do to help prevent it? I have always used full synthetic oil but I am wondering if shortening my changes from 5000 miles to 2500 will help prevent this from becoming a full blown problem. I am interested in your thoughts. Thx

Pretty amazing approach to repairing a collapsed lifter. I enjoy the part where you explain how or what caused the lifter collapse in the first place. Avoiding the trouble spots and a repair would be my first choice.

keep clean oil in your car & it will not happen

I live in Texas and my Silverado has the lifter tap also. But only in the cold winter months, and only until the engine warms up. No loss of power or check engine light either. I'm lost.

Love your videos, they gave me the confidence to do plenty things on my truck so far. I got a 07 Escalade with 144k on it. It was badly neglected by the previous owner. It's got the tick and low oil pressure. So far I have changed the oil to Mobil 1 5w-30, changed the oil pressure sensor and filter, new plugs and wires, deleted the air ride and active suspension, and changed the motor mounts. My next project is to drop the pan and change the O-ring and finally order your tool and free the lifter if I have one stuck. I have Torque pro, and it did not detect a misfire. My question is, do I have AFM/DOD to delete and what else do you suggest if I eventually want to swap the cam to a stage 2 and tune?

thank you it worked again !!! two diffferent 6.2L engines both #4 cylinder

Nice technique and explanation!

I have a weird one for you. What are your thoughts on the following?...I have a 2007 Suburban with the iron block 5.3L. 328K miles. Never had any issues with the engine other than oil leaks and oil consumption. I did the updated valve cover, AFM shield and cylinder soak at 202K miles. This helped considerably with oil consumption but lately, I've been seeing oil consumption with blue smoke at startup. I bought valve stem seals a while back and decided to install them today. Went through the proper procedures to install the seals and torque the rocker bolts. Turned the engine over by hand a few times to make sure everything looked good. Started the vehicle and it was apparent immediately that there was a misfire. Ended up being cylinder #7. Pulled and reseated the plug wire and the misfire was gone and the engine ran perfectly. Revved to about 3K RPM and instantly got a lifter tick on the LH side. Pulled the valve cover and #7 exhaust has about 1/8 of movement when the valve is supposed to be fully closed. It never went into V4 move as it was only idling in my driveway. I did a quick drive around the neighborhood to see if the switch to V4 mode would fix the issue but it did not. However, when in V4 mode, the tick completely goes away so the lifter is still collapsing in V4 mode but doesn't appear to be fully opening. I pulled the valve cover and removed the #1 and #7 exhaust rockers and the #7 push rod sits about 1/4" lower than #1. I checked the push rod and it's perfectly straight. It still runs great and has no misfires. I'm at a loss as to how the valve stem seal replacement process could have caused this. Certainly it can't be a coincidence.

Hey I have a repair shop in East Central Minnesota. I have been wrenching on cars for almost 20 years now and i have learned to say the least a few very useful things from your videos. I recently purchased and used the "stuck lifter" tool and the vlom plug for 2012 silverado 5.3l the tool and plug worked as they should but my question for you is..... Where can I get the necessary "pcm tune" done at?

Collapsed #4 intake last week. This worked flawlessly. Bought the tool, got the tune done, drove 500 miles today with zero issues!

I have a 2013, 5.3 Silverado with a misfire on number four only at idle. I checked the compression and It is low on four. It was 127 dry and about fourty pounds higher wet. No ticking and all lifters are moving fine, I pulled the valve cover to confirm. About a year ago I had an episode with the same cylinder misfiring with the valve noise. After running for a while with the Range disabler it stopped naking the lifter noise, so I had it tuned and all seemed fine until now. Have you seen this before??

Fixed my tahoe using just the HP Tuner, no more lifter issues.

I cannot thank you enough for this video and the tool to perform the repair. I was quoted between $5-$8,000 to fix or replace my engine. These were options that I could not afford, so I went online to find options and happened upon your video. My mechanic was very skeptical that this would work, but the worst that would have happened is that I was back where I started. The work was much less complicated than I thought and the results are amazing! The truck starts and runs smoothly. The power delivery is better, and the transmission seems to shift better than before. THANK YOU THANK YOU! If anyone is on the fence, take the dive. What do you have to lose?

I have a 2014 GMC Sierra 1500 with 5.3 and cylinder 3 misfire only at idle. New plugs, wires, injectors, intake gaskets and cleaned intake valves. Compression test showed good compression on all cylinders even #3. Swapped coil packs but misfire remained at #3. Getting a new pack tomorrow just in case and next step is to take valve cover off and see. Any thoughts? Could this technique work for this year engine?

Have an 09 gmc 5.3... starts up fine and smooth idles 35 psi oil pressure. Can drive it 30-40 miles and sounds like Mexican Roofers....No misfire....codes etc and oil pressure doesnt change!!!

I have a '15 silverado 5.3 . Shortly after Thanksgiving 2020 I blew a headgasket. While inside the motor figured I'd replace all the lifters as well. I've had the DOD turned off for almost the whole time I've had the truck, since 2018 with 27k on it and now she's almost at 100k. Two weeks ago I had a misfire in cylindar #6. Towed her home and started troubleshooting . Hoping it would be the coilpack because the packs were the only thing I didn't replace on the "headgasket rebuild "... It wasn't. Looks like a colapst brand new GM lifter ! The rocker doesn't move while engine is running and when it's off there's a ton of slop rocking back and forth on the rocker . Telling me it's a colapst lifter or a damaged cam. Oh and the rod looked fine as well . I guess my confusion comes from the fact that I don't have the DOD active . I went ahead and ordered your "premium tool kit " for the lifter. Havnt really decided if I want to use it or if it's even meant for a 2014-2018 GM gen 5 LT 5.3 engine. Im considering a complete delete, cam n all. Just not sure if I want to take that big of a project on right now. Any advice ?

I tried turning the engine over, an the arm is still not lose. I assume the lifter is stuck, but I’m confused on why the rocker arm is not loose like all of your other videos. Any ideas?

I never thought of this going through possible collapsed lifter now

Great video 👍

Hey man! I bought your lifter release tool and it came today however when I removed the rocker arm the rod came right out with my hand is this a bigger problem?

I have an 08 Burb, 5.3 O code flex. No. 4 cylinder lifter collapse. Watched your vids, bought your awesome tool, followed procedure to the letter, rap a tap tap and lifter popped up. I pushed the push rod back down on lifter and felt/ heard a click. Put rocker back on, snugged, pulled engine by hand through 2 turns, watched rocker rock. Broke all tabs off on vlom and blocked oil passage w your collar.Re-gasketed everything, torqued to spec, hit the key and viola.. However, I’ve run into an issue P304, misfire on that same cyc. Changed plug, coil, wire, injector, propane and sprayed everything can find No vac leaks. Did notice LTFT bank 2 is always neg, avg around ned 8 to 10, sometimes 12 and higher in city but neg 3.6 highway speed @ 2600 rpm. When I come to a stop idle is initially good and steady at 600 ish rpm but then within seconds slowly falls to 400/450 and shakes a little and I get Stabilitrak, cel flashing. My scanner says FP is 43lbs most all the time, changed pump, did the same, sometimes it goes to 58 but then falls back down, after shut down rises to over 60. Thoughts on that miss? Have not done comp or leak down yet. Sigh.. so close. But your tool worked great!

Bummer hopefully it's not a spun lifter because of a bad plastic guide. Pop the cover off and use the starter to crank it over while watching rocker. If it works at first then stops it may be spun. This is the worst case scenario for you. Something you can't anticipate or prevent while having AFM lifters. When it happens it wipes out the camshaft.

@@ericmausolf8682 I think the fuel pressure is irrelevant. It's likely more related to open vs closed loop. The stft might sow close to 0 but I bet the ltft is way off being 1cyl worth of extra fuel is being added to other cylinders while using less air. You probably shouldn't be driving it like that though. There is a puddle of fuel sitting behind the intake valve that's not opening. If it leaks into that cylinder after shutdown at the bottom of compression stroke, you could be risking a hydrolock condition.

My 5.3 sounds exactly like this. Sounded just like it was on top of cylinder 1. I replaced all the lifters and rods and the noise persists. Any thoughts? Doesn't sound like rod knock. I am going to try to rev it tomorrow maybe it just needs that

I have a 2017 silverado went on a long road trip will the release tool work ? Much differences in the new generation?

I have a 2010 suburban 5.3 had a collapsed lifter. Replaced all of them and the valley Pan. Started it up and it bent a lifter.the lifter not rod. So I put new lifters in and same cylinder collapsed again. I am lost any help or advice would be great

Hi, Have a question: after this procedure and once the lifter is realased, what are the chace that it stock again if I use one ODM AFM disabler ? Thanks a lot for what you do for the GM community

2012 escalade 100k mile 6.2 dod vvt engine knocks/ticks on start up. 99% gone after driving for 5 minutes. Stethoscope picks up the noise on driver side block just under the head. All rockers moving and 200 psi compression on driver side cylinders. Exhaust manifold bolts tight. Any ideas sir?

My 2015 Silverado ended up being a bent pushrod...lifters look good...so if this happens to you simply take valve cover off and rocker arm..check for bent pushrod ...if bent try changing pushrod first and see if does the trick...don't go straight to this hack...could be a defective pushrod...but I didn't know so I tore it down...since it's apart I'm changing lifters on cylinder that had bent pushrod...good luck...hopefully you will check pushrod instead of taking it all apart...

Mine only throws p0300 but my scanner shows massive amounts of misfires on cyl #3 and occasional on #2, i find it odd that it only throws the random code. Hoping theres something in this video to get mine back going haha

I'd also run rislone every oil change to help keep the engine clean

what prevents it from collapsing again? good video

Lifters colapsado? En mal estado? La solución fue limpiarlo o ponerlo nuevo?

I just traded for a silverado and it has a tick not horrible but it still ticks I used tranmission fluid in the oil and it helped some but should I run 10w 30 oil or the 5w 30 oil the is recommended? Thanks

Mine is exactly like this only intermittent. It will come and go. Sea Foam an option?

so if it is misfiring will this still work i think al dods have some degree of colapse because i can't tell any difference when removing coil plug

When mine starts missing the service stabitrak and traction control off comes on... it doesn't sound bad as your vehicle

Have you heard of a P219A? Bank 1 driver side Air Fuel ratio Imbalance. No misfire or any DTC’s besides this one. Possibly 1 or 7

@CrazedPerformanceRepair

Жыл бұрын

Cylinder number 8 is not a AFM cylinder. It can't fail the same way the AFM lifters fail. The AFM lifters failing comes down to oil pressure at the lifter during activation. If the oil pressure is below 26 PSI at the lifter when it activates the locks will bind. This causes internal damage on the AFM side of the lifter thus leading to the lifter locking up when it activates. That's where my lifter trick comes in. Doing it freeze up the lifter and turning off the system keeps it from happening again. You need to make sure that it applies to you and your situation though. There is more than one way the lifter can fail and that is only one of the ways. If you have a floppy loose rocker you most likely have the scenario I use the tool for.

You might just have a bad oil pump o-ring. It is very rare for these pumps to actually fail. I should be releasing a timing chain video this weekend that shows how to remove the oil pan and pump. If I release that video this weekend you can use it as a guide to pull your pan and replace the oil sump o-ring. It is a cheep o-ring, a oil pan gasket and a oil change worth of expense, so it is not to much money to do. It is also a very common problem and worth doing anyway if you have the skill and time to do it.

Thank you so much for your help & getting back to me , we'll keep an eye out for your new videos as they've been extremely helpful. We'll get the parts this week & be ready to go after your video comes out. Know it'll be a while for you to post that gives us time to finish up our car 😉 good timing was meant to be. Take care stay safe & again thank you for your help & videos.

What keeps the old lifter from sticking again?

With the majority of these cases involving dirty engines, it seems to me that the oil quality (or whatever GM calls it) monitoring system isn't worth a damn. I don't care what GM says, I'm changing the oil and filter every 3000-4000 miles! Remember GM's "recommendation" for oil changes comes from the company that wants to sell you a new truck!

Have you ever tried putting a holes on hose clamp on the lifter once you take in the rocker arm off and putting back pressure into that lifter? Just wondering if that would be a next step without having to pull the valley cover and whatnot

It's technically incorrect to call it a collapsed lifter. It's technically a failed AFM portion of the lifter and has nothing to do with the normal hydraulic side of it. Unfortunately if I word and label things that way the video would never reach anyone. What happens is the AFM locking paws on the inside AFM portion of the lifter damage the shelf on the outside portion. Then when the lifter activates it's AFM the inside portion gets stuck to the outside portion because of the knurling effect that the damage caused.

Does it works with a hemi 5.7

I've poured sea foam inside oil and fix similar issue 😅

I'm planning on buy a Caprice with the AFM, about 35k miles no more then 60k. Should I have the AFM lifters replaced to help prevent the inevitable?

Just disable the system electronically first. A great source for this is LT1swap.com

Just ordered your kit. This is my second Silverado and I had to rebuild the top end on the first one. New truck just started ticking, true to form. Question, where can I send my ECU to have the DOD disabled? I was going to buy an HP tuner and do it myself but they seem to be on backorder. I use a Range AFM disabler now, and it works but I have to pull it and drive a few cycles every year for the readiness monitors to activate -- gotta love state inspection...

Lt1swap.com hptuners has gotten way too expensive.

I have a 2018 GMC Sierra 5.3L V8 which had a misfire at cylinder 1 (P0301). I can hear ticking noise coming from the same corner of the engine as shown in this vid but not all the time. The knocking is louder when the pedal is pressed and it starts to misfire and CEL starts flashing so I release the pedal when it starts misfiring. I also notice the oil pressure rises when it misfires and knocking noise comes simultaneously. My guess is the lifter collapsed, any feedback would be appreciated before I send it in to the shop

Yes it could be, all depends on what has failed and how.

I feel like an idiot for paying almost 3,000 the first time lifter collapsed. It collapsed 9 months later. I bought Dudes tool and plug. Received it in two days. 12 hits and POP. If I knew about deleting the 4cyl. Mode I would have done so the first time. I am about to clip solenoid gaskets. Do I do all of them? Am I just trying to get orange rubber removed? Also, can I drive it in “tow haul mode after modifications just until I can get it tuned? My Vlom is just caked with sludge. It makes me question if the shop did all of what they charged me for. Hard to believe they would put that back on like that. It is Nasty! Considering replacing it. All in all, even if this doesn’t get my 2011 back on the road…I have learned so much and it costed me so little. Thank you so much!

Just chisel the gaskets plastic and all out then add plug. You could clean it if you want with degreaser and water. Then dry it. I recommend lt1swap.com for the tune unless you can't go without vehicle while the ECM ship's. If it needs to be done fast but a tuner box and do it yourself or find a local speed shop. You can use manual for a while if need be to

So….I’m getting good at tearing down top of motor to get to oil towers and rocker arms. I used the tool and plug a few days ago. Succeeds!….but wait my lifter collapsed again. So I watched the videos again. My problem was that I only removed the orange rubbery gaskets that feed the oil towers. You actually have to remove or chisel out a part of the black plastic as well. My VLOM (valley plate) is not black on the underside like the one in video. It is shiny metal colored. So I mistaking did not remove enough material. I am confident now that I did all you said. Even threw out that pesky noise plate thingy in the rear of motor. Pain in the butt to reinstall with that in the way. Sending my ecm in now to get system electrically modified now. Thank you so much for all your help. I was bumming when my truck was down. It’s pretty crazy how your tool release, a hammer, and a few common tools can fix a pretty major problem. Thanks again!!!

I have a 2008 suburban with this crap afm with an 5.3. I have issues in just one cylinder. I pulled out spark plug and it has oil in it, does that mean I have a lifter issue or a piston ring? I have 170k miles on the engine

I have a Chevy avalanche 2007 and I have the same problem And a brilliant brilliant Mecanic. He told me pour into the engine 1 quart of transmission oil and drive it for an hour and then change the oil and all the spark plugs. It should be fine. I did exactly what he says and magic happened. Everything became so smooth I couldn’t believe it. Even the oil pressure went up all the time it was low on the gauge.

Dirty engines do play a factor if the contamination causes a drop in oil pressure to the lifters. The other huge factor is general wear and tear. As these engines age the clearances get bigger and the volume of the pump can not longer keep up to maintain above 30 psi in all conditions. The system fails when the locks can't be activated fast enough. I would turn off any system that had over 100,000 mi or 160,000 km but if it was my own vehicle I would shut it off as soon as warranty was up.

@AhmadAboulFarag

I changed the oil to a higher viscosity after popping the lifter... everything seems fine so far. My 07 Tahoe has 250k miles on it and I am guessing like you said larger clearances need higher viscosity... but then again you lose some engine power along the way due to higher friction. These engines are very expensive where I live. Will cost me around $10k to get a new one. Might as well change the entire car.

No because it is sorta a myth. They fail because of lack of oil pressure during AFM activation which sometimes is caused by sludge. Issue is when they stick it's not sludge holding them, it's damaged metal area inside the lifter it's self for the AFM portion of it. See my long video to see the part that gets damaged.

oh I thought that they had far less miles than that. seen videos at the dealers replacing the lifters under warranty. at any rate, I blame the oils. or actually put the blame on the manufacturers recommendations to reduce additives like zinc because it damages the emissions components. to me that's putting a bandaid fix on shitty designed emissions components. i'd rather run oils with higher zinc etc and replace converters which is a hell of a lot easier and less expensive.

@@blue03r6 it happens because of lack of oil pressure during activation. This causes the lifter to bind internally and create a knurling effect. It's not from contaminated oil necessarily. More a wear and tear issue over time dropping pressure. The early ones can be from contamination. Lack of oil filter changes causing pressure to drop when it plugs, could also be that screen underneath the oil pressure sensor that plugs up causing it to drop pressure at the lifter.
