Collapsed Lifter No Misfire, Don't Pull The Heads Yet Chevrolet AFM DOD

[@marionmcknight4533]

Does this apply to a 2019 yukon xl 5.3.

[@CrazedPerformanceRepair]

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 kzbin.info/www/bejne/rKjHeoF7qN6MgpY -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.

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?

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.

Replaced all lifters on passenger side. I think I know what I did wrong. I left the rocker on and didn't let it expand all the way. Either way awesome trick. Put 20k on it since ,cheers

[@CrazedPerformanceRepair]

What you did wrong was not turning off the system. If you haven't turned it off yet, you should. These systems once failed tend to fail again within the first year or two after lifter replacement.

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!

[@CrazedPerformanceRepair]

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]

These are now normal values right? I have noticed in past when that mis gets bad, FP has gone from 43 to +55 lbs . Got P304 during that heavy mis.. put in P, killed a/c and smoothed to just poor idle. Odd that FP rise to normal causes mis to exaggerate.

[@CrazedPerformanceRepair]

@@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.

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 ?

Having the same problem on #6, I have already taken off the cylinder head once and found #8 lifter actually did not have the small hole in it!

Would like to get your tool so I can try procedure before I have to take cylinder head back off for new #6 lifters. Thanks for the great video!

[@CrazedPerformanceRepair]

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.

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.

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.

[@CrazedPerformanceRepair]

@@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.

[@CrazedPerformanceRepair]

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.

I unbolted the rocker .. let if run again with my finger on the pushrod and could feel it moving up and down so I don’t think cam is bad. I guess what I’m asking is have you ever ran across this , would your tool get this unstuck ..before I pull the head? Thanks in advance

[@CrazedPerformanceRepair]

Tool won't help. Could be that your lifter has spun The lifter could also be spun, using the starter relay with the key off, spin the engine over. Make sure not to jump the wrong terminals as it could damage the ECM. Vlom Must be on for this test. While it is spinning watch the suspected rocker move. Make sure that it rocks at least 6 to 7 times before you let up on the starter. If the rocker stops moving before then it is getting fed oil pressure and is likely spun. You can determine this by looking at the side of the lifter. To see the side of the lifter you need to pull the VLOM and clean out the oil tower of the suspected lifter with cleaner and shop air. Once cleaned you can look down the oil tower and if you see a hole in the lifter it is not spun. If however you see only shiny metal or a flat surface then the lifter has spun due to a bad plastic lifter guide. When this happens you will need to replace the camshaft and all lifters. This would be a good time to do a full AFM/DOD delete where you remove all AFM components and replace them with non AFM components.

@CrazedPerformanceRepair How exactly have you came across this many customers with this issue? Do you have an independent shop?

[@CrazedPerformanceRepair]

Yes, I run my own gig from home. I recently moved and am building a bigger shop now.

[@FlawedOffroad]

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

[@victorburac6918]

Will that work on a 4.3 engine as well?? 2020 chevy express. I have like a valve noise around cyl 6 uppon acceleration and misfire that doesn't do the check light

[@oldschooltamiya]

Yeah I found it yesterday thax will be getting one soon..

[@1967novss]

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

[@traviscornett704]

Will lose vlom bolts cause a misfire? Ive been chasing one all summer long

Not likely, is AFM disabled?

Awesome work nice video, I have a question I have a Mercedes that I believe have the same problem do you have a shop? My I can bring my car to fix it?

[@CrazedPerformanceRepair]

I'm in process of moving my shop to SE corner of South Dakota. So if you are with in driving distance of that area you will be able to bring the vehicle to me for service.

[@jeremykissner2281]

Does a stuck lifter always make noise ? I have a cylinder 4 misfire replaced plug wire coil.....

[@CrazedPerformanceRepair]

No, but usually. It does always have a floppy rocker if it's collapsed. You could have a spun lifter too.

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!

[@CrazedPerformanceRepair]

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

[@paulvanberkel978]

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!!!

[@OMARORTA12]

Lifter just started ticking about a week ago . No cel. Just a tick

[@Michael-jp4oh]

I picked up an LS engine with that same problem ( tick but no collapsed lifter). The tick was from metal that wore away on the lifter roller and chewed up the cam lobe.

I need help man, 07 suburban 5.3, misfire at idle only and no noise or ticking, checked with a scan tool and misfire counting on cylinder 2 and 5 I already changed plugs coil and wires still persisting.

I wish you would of shown how to actually position the tool down the hole. Which way should the angle face?! I appreciate the tips but man I’m scratching my head here and don’t want to go tapping anything without an answer to how to properly position this tool in my 06 envoy denalu

[@JMcAutoWork]

I've watched like 3 of your videos and I still dont understand how this is working... I need to see a cut away or a drawing or something to see what is going on here and how this in fixing the stuck lifter. I'd love to be able to do this for some people who don't have the funds to get lifter replaced.

[@CrazedPerformanceRepair]

Contact me on my website. But basically it works like when you have a bolt stuck in a socket. Set the socket on the concrete, wack the side of it with a hammer and the bolt is no longer stuck. I can get you a picture of a cutaway if you pm me at crazedperformancerepair.com

You don't need that really unless you mess it up real bad take some tranny fluid spray in the intake write down the carburetor try not to get it in the carburetor try to spray it down right into the intake when it's running now come right back and quiet right down does this does this 90% if they don't come back up you messed your lifters up real bad

[@chineseempanada420]

Hey man I’m in a bind and was wondering what else I could use to release the lifter? I don’t have enough time to order your tool?

[@CrazedPerformanceRepair]

I think some 1/4 in extensions can fit. You will just need to cut and profile it.

Hello there. I hava a Code P0302 on a 207 Tahoe (since is a piston that doesn´t have a AFM conected lifter) I wonder if I have to do this procedure? Thanks.

This procedure won't help on the non AFM cylinders. Check the basics first.

Is there a certain position the piston or lifter or cam needs to be at when attempting the release trick? If so what would it be?

And how can you tell when ur at the correct position?

[@sunnicivang1093]

Does this work with the V6 engines...?

[@CrazedPerformanceRepair]

Yes sort of, but it's not worth it. The 60° v6s that have AFM can I have the lifters replaced without pulling the head so it's not worth doing. Just replace the lifter and shut the system off or solve the wax oil pressure drain activation issue.

[@jonyoung6775]

Hey bud great video. I have a question though. Will it always through some type of code? I have a 13 Yukon with 135,000 miles and I’ve noticed a slightly louder than normal ticking on the passenger side but no codes. Seems to run fine but I rarely drive it as it’s my wife’s.

[@stephenfaulkner1448]

Mine is not showing misfires. Sounds like the tic is on #1. Does use oil and no pressure. Advice?

[@CrazedPerformanceRepair]

No pressure from plugged screen under oil sensor. Tick from collapsed lifter caused from low oil pressure during lifter activation. Oil consumption caused from PCV portion of driver side valve cover. Modify it like I do in one of my videos and you should be good. As for the tick, do the lift release trick, the VLOM mod, and the tune to shut off the AFM and you should be good.

[@roopaui]

what is that air tool you are using and where can i get it or will a regular air hammer work

[@Captinfun101]

It’s called a needle scaler ( with the scales off )

[@TheTechGuider]

@CrazedPerformanceRepair okay so figured out my exhaust valve isn't fully seating. No.compression. But when I back off the rocker arm bolt it seats fine with plenty compression. I even strarted the truck and it ran great. What should I do??

[@CrazedPerformanceRepair]

You prob have to pull the head. The valve might be sunk in the head or something. Check valve stem height and compare it to the others. If it's sitting higher then the rest it has sunken in or worn out.

[@TheTechGuider]

@@CrazedPerformanceRepair wasn't the valve. Took the head back off and replaced the other lifter in that cylinder and boom ran great. Idk what was going on because that lifter looked fine. The other one was visibly collapsed. But I guess both were bad.

[@CrazedPerformanceRepair]

@@TheTechGuider interesting, I've heard of only a couple do that. It happens but isn't very common.

[@DJKadilac]

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?

[@jamesjudd6577]

so for the direct injected 6.2 2015s with a stuck lifter, do you think this works? ive seen several videos claiming it does, but not sure how to verify. Tearing it down including removing lifters and non-replaceable fuel connectors is a major pain

[@jamesjudd6577]

removing fuel injectors that is

[@CrazedPerformanceRepair]

Yes it definitely works, however be aware that they are prone to bending pushrods and it's critical that you do the VLOM modification.

[@HeastrineKarsikas]

Try to just to spray some transmission fluid down in the air intake when it's running if it's a collapsed lifter it will stop making a noise almost immediately if it doesn't then then the lifter is messed up real bad you had to replace

[@ubethejudge69]

Oh hey, 2016 gmc 6.2. Had tick, 90,000km, dealer said bent pushrod. i asked if the lifter expanded back and is in that current state, they said yes and i said install a push rod and I bought a range dfm. Its ran for 40,000km with just slightest tick. Nothing tick loud like it was while it was bent push rod. I have no misfires on any cylinders with scanner at idle. I'd like to monitor the situation. Any recommendations? Since the AFM lifter is just acting like a normal lifter now could the slight tick mean that maybe a slightly longer pushrod could technically resolve that issue if it really is a gap between lobe/lifter wheel? I'm getting 20 mpg on highway. It's fast. Only other sort of issue is a delay when accelerating when coldish. almost like the hp fuel pump may not be able to supply fp or tcc . Anyway perhaps unrelated. or maybe the hi po fuel pump is the ticking. Using stock gm oil and changing it every 5000 km , thanks great video

[@CrazedPerformanceRepair]

These have interference issues with the lifter in V8 mode. If you pull the pushrods and inspect, you will likely find marks on the side. If so that's your tick and the solution is smaller diameter heavier wall pushrod like the ones I sell.

[@ubethejudge69]

@@CrazedPerformanceRepair Thanks, so the cup of the lifter where push rod seats is a small gap, hence the tick and the witness marks you speak of should be there or when you say "side" you mean up elsewhere along the pushrod? Thanks for teaching me and offering your pushrod for sale. I look forward to your reply.

[@CrazedPerformanceRepair]

@@ubethejudge69 it's about an inch up from either end of the pushrod. It hits the spring on the lifter or the hole where it goes through the cylinder head.

actually found that video and it is you, i see what you mean now, i can't believe how far down in the lifter the rod sits on afm lifters vs normal ones. i had only seen normal lifters. i always thought the tick meant the camshaft is being hammered by maybe 0.0010 clearance issue. ok awesome thanks man
