Ticking, Clicking Noise Coming From Your Engine? Diagnosing Collapsed Lifters!

For More Info visit us at: 1aau.to/h/cKE/
In this video, Andy diagnoses a top end clicking or ticking noise in our Chevy Avalanche! Andy locates the clicking noise to the top driver side of the 5.3L V8 engine, and also discovers an intermittent misfire in cylinder 1. After removing the valve cover, he discovers a very loose rocker, which is the source of our noise. He determines the rocker is loose because its lifter has collapsed, meaning it's not pushing up on the rocker when activated by the camshaft. The fault is in the AFM (active fuel management) lifter, which can be disabled by engine management to make the engine more fuel efficient. The lifter failed, so it was not able to be activated again by oil pressure. Andy replaced the lifter, and after that, the noise was gone!

the mechanic in this video deserves a grammy award for always coming through with the best mechanics instructional videos - not only his efficient-minded tips with the technicals of it but from a cinematography standpoint; I think he really understands how important seeing it being done is to the viewer

[@fredcee5073]

Yes because some of the thing he did I didn't do. I watch other videos an they didn't show none of the things he did so I have to go back in and redo some things.

[@steveschwenke9636]

This was by far the best video showing you the complete breakdown and how to complete the job. No gimmicky fast forwarding like others have. No stupid short cuts . Everything is shown from the first to the last bolt . Made the job so much easier to do knowing what I needed to do it. Thx for all the great videos

*READ IF THINKING OF CHANGING LIFTERS* So I did this job* 08 Chevy Silverado 5.3 (#4 lifter went out) 200k miles I am not a mechanic. I got a quote of $3500 to replace all lifters. Felt confident I could do this, so I figured since I got the intake off I might as well do all lifters (big, but possible job). I utilized this video and some others, which were pretty much the same and all very helpful. I did it a garage I can use on base and by myself (minimum help). Took me a total of 27 hours (again not a mechanic, and that was with cleaning heads and small struggles of trying to dissable/assemble, and some store visits for parts). Parts where I struggled: exhaust manifold dissamble/reassemble (especially gasket install). Couldn't find "angle" torque wrench. Bought one at Harbor Frieght for $140, and it so happened to be same one as the video lol. Everything worked. Don't freak out if your truck don't start at first, the fuel line was disabled so fuel is kicking back in. On the 2nd turn it started. Recommendation: do your research on vids, get the parts ahead, and good luck!

[@dl1130]

Not only are you an excellent mechanic, but I didn't hear you cuss once! It is refreshing to see someone who loves what they do! Great job and video!

[@TroyStevensStelzerPaintingInc]

Your camera work is outstanding. First time I've ever complimented a KZbinr on their camera work, but it truly makes all the difference with repair videos. It's what separates a good vid from an exceptional one. Thank you.

[@joffreydepoplimont9523]

Oh. My . God . I had that problem 2 years ago and could never find a good video. I know some parts of mechanic, but never touched a lifter. First I instruct myself, over instructions, books, or tutorials. I could never find a good tutorial for this explanation. You just did it. I am a huge fan of your others videos, just checked a suspension arm replacement yesterday on your channel. It's just absolutely AMAZING ! Thank you so much. Please continue like this ! I'm living overseas but I have a huge US cars collection, and your channel helped me a lot for years! But this video truly deserves an award, or, at least, my first comment on your channel ! Thanks again. It contains a lot of comments. No skippings of disassembly steps. A great video quality. A clear voice. I take my hat off to you.

[@jchrg2336]

I do enjoy watching you execute the job Ps: one tip it might be handy to know that during tightening head bolts inbetween the passes of 90° and 70° etc you do want to wait ( or eat a couple of crackers or drink a cup of coffee) because the bolts and threads get hot during that stage and they might snap and break

[@Z0656]

As an option to outright replacing the lifter we have used Blue Chem's High Performance Cleaner (Oil System Cleaner & Hydraulic Lifter Care) with excellent results. In the two incidents we have used this process on 5.3L engines which sounded exactly as this engine did, the chemical cleared the varnish build up and released the stuck lifter. Both engines had well over 150K miles and neither had been well maintained. Its been months and neither customer has returned with a similar knocking noise. I did speak to one of them four months later and still no knocking. Both were quite relieved as you can imagine. I'm not a proponent of additives but I can't ignore the success we have had. Obviously this process will not resolve all knocks but in my view its well worth a try.

[@7733marietta]

I was watching a Mazda video for my car and your video was next in the playlist for some reason so I watched it. I was fascinated and entertained. Thank you for being so thorough and even though I hope I never have to replace a lifter, I watched your whole video. Good job and I’m going to subscribe right now!

[@Al_Swilling]

Great video. Thanks for posting it. That's why I like my old 1990 Ford F-150 with a 302 (5.0 liter) FI engine. The intake manifold is between the cylinder banks, and beneath the intake manifold are the lifters and push rods. To replace a collapsed lifter, all I have to do is remove the intake manifold from the top of the engine, loosen the nut on the rocker arm above the collapsed lifter, swing the rocker arm out of the way, remove the one push rod, remove the collapsed lifter, install a new lifter, put everything back together, and adjust the affected valve. I don't have to take off the exhaust manifold or remove the head, just the valve cover and intake manifold, which are easy to get to. My little Honda Accord LX, 2.3 liter 4 cylinder Single Overhead Cam (SOHC) VTEC engine, on the other hand, is a whole different system.

[@regsmith7604]

Drain out a little under a quart of oil, put some ATF in the crank case and let it idle until that lifter stops making noise. Change the oil and put some more ATF in, drive it. Call customer to come get it, advise customer to do regular oil changes or they’ll destroy the motor.

[@mariorrodriguez535]

What a mechanic you could be!!! Didnt you see how bad was the gaskets? Off course you setted up your customer for a next visit. For anti-freeze leaks, oil leak and gunky sparks ending story change engine, great bussines

[@charlesparr1611]

First video I've seen off the channel, and I like the way this guy just sort of pokes around at the car, narrating his own thoughts, and also how he seems to suddenly realize we are watching every once in a while and the dialogue sort of firms up....And then of course he trails off because he's actually thinking about the car. It's really effective, because it pulls the watcher in to the reasoning process, trying to follow along with him and figure out at each stage what he might be looking for. Most channels doing this kind of thing armoire like handing you a recipe and a set off instructions, which is fine if you have no interest in the actual process of figuring out what the problem is (and sometimes you don't care about that, because yeah, you know it's the starter, you just need to know how to be sure which kind of part to buy and how to swap them), but any time I see the word 'diagnose' in. the title, I want to see the thinking and the little comments like 'we're gonna need a valve cover gasket', or 'you want to be careful around xxx', because those are exacdtlythe things of value when a rookie learns from an expert. yet for some weird reason so many channels leave that stuff out, seeming to feel like letting me watch you wander down a false trail, or bust a plastic wiring harness clip will make me less likely to watch. No, thats where us idiots out here learn the most. Unfortunately I work on stuff that almost always way too old for a scan tool, sometimes its too old to buy a part for now that I think about it. Still, despite this being no use to me at all in the end, its still a great video. Even the camera work is shockingly effective, all things considered, although shaky-cam (tm) usually ticks me off, here they manage to keep it on the subject and angled well. Not that I have anything like the gro9unds to complain, I couldn't do it at all and know that well... good work guys.

[@alexv5050]

I wanted to thank you for this video I have two suburbans both a 2014 and a 2012. The 2012 was making a loud knocking noise like you had in your video. I used a scanner and it showed me that cylinder number six was misfiring. Although I’m capable and confident in doing things like brakes, rotors, hubs, shocks, struts, and things of that sort. I was very hesitant to attempt this myself until I saw your video. I was able to successfully get everything apart without any problems, and I found a loose rocker arm on cylinder number six intake . I’m at the point now where I just loosen the exhaust manifold on the top side and I have to get underneath and take the bolts out to completely remove it then I will remove the head . I hope everything else goes as easily as it has so far but again, I would’ve never attempted this without your video because it showed every necessary step without any fast forwards. The only tool I had to buy was the fuel line disconnect, flange kit with having used speed perks. It only cost me five dollars at advanced auto.! I will update more as my progress continues. Thankfully this is not my daily driver, so I can kind of do it at my leisure. I did have one question if anyone can comment should I replace the valve cover gaskets they seem to be in good condition but my neighbor said that they should absolutely be replaced if doing a job like this . Also, I’m a bit undecided on if I should replace all the lifters, and push rods while I have it torn down this deep? Any input is appreciated.

Need to fire all current engineers and bring back retired ones. No reason the cylinder heads should have to come off to change the lifters. For years with this style of engine once you took off the intake you had access to lifters. No reason this had to change so don't try to justify it

Absolutely awesome job the only thing I would have done differently is I would have replaced the opposite valve cover gasket and the plug wires on the opposite cylinders. And this customer needs to start changing their oil and probably using a better oil to prolong the life of this engine as there was a lot of oil coking in those valve covers a obvious sign of neglected oil changes and maybe cheaper oil.

That’s a pretty awesome find in the amount of time you spent on it. I have k series engine that makes a similar sound only when you rev it up but the engine itself runs fine. I can’t stand the sound though so imma take off the valve cover and I’m sure it will be one of my lifters. I did a head gasket a long time ago on it and I remembered inspecting them and some of them moved a bit more freely than others so that will be the first thing I look into

This video is very informative and helpful the presenter did an awesome job and the video is one of the best detailed repair videos I seen in KZbin... however, I didn't like the idea of just replacing one lifter only. That really seems like poorly made repair. When replacing lifters on these vehicles, it is a good idea to replace all lifters and lifter tray guides in the affected bank. Also the VLOM should be replaced. A faulty VLOM can cause the AFM lifter to collapse. I work for a GM dealership and I am a master/ GM world class technician
