Got to say its a great video. Impressive and informative!!! I have a 5.3 with 380k miles. Recently changed the oil pump, pickup tube, timing chain, cover, radiator and all 4 O2 sensors. Now Im getting multiple misfires at #4 & #6 About to take the valve covers and check the valves just like in your video. Again thanks!!!
I have the same issue. #6 is tapping away. There's a tool crazed performance sells to tap the lifter. Is removing the rocker and tapping the rod on top of the lifter essentially achieving the same thing?
I made that tool by finding a rod that fits down the oil hole then I ground it at an angle then a slight concave on it. You’ll feel it seat in place as you spin it. The plunger in the lifter will pop out too far so just use the push rod to re-seat it
I thought stuck lifters was caused by bad oil like taking too long between oil changes? I have a gmc 2007 5.3L and my lifter on cylinder 7 got stuck. I have them all out now and will replace all of them. What do you recommend to make sure my afm lifters dont do this again? Im gonna buy a new updated vlom as well. Thank you.
How did you know the camshaft wasn't scored? My shade tree mechanic is taking his sweet time on my truck its a #6 misfire. He's had my truck for over a week and wants to look at the camshaft now, after he tried to tell me lifter failure was rare! Ive always had 20-40psi oil pressure. I feel like this guy is going to try to hose me for a camshaft
There are cases that the cam could be damaged. If the lifter has turned its most likely damaged if it’s still running straight then it’s probably just stuck like this one was
Brother you just saved me alot of money. I had some jackass mechanic tell me I gotta have the whole engine rebuilt. I knew he was full of shit. I had the exact same problem in my truck I done everything you did with the lifter and put it all back together and truck runs fine again but I did replace the bad lifter

I've released a few with a #2 screw driver, seems to work the same way lol

The rod you made… how thick is it? Looks about 1/4”-5/16”. I need to make one.
Nice moves on that lifter...
Where does the lobe need to be when you tap on the lifter?
@@frankgarcia975 it’s been awhile but I don’t think it mattered.
What tool is that?

@@paquesepas6696 I had the AFM disabled so it wouldn’t do it again.
DoD lifters..... The ticking time bomb!
What is the issue
what oil you using everything looks very clean
What does your tool like like for loosening the lifter sir
He used a old push rod
What year of ls?
So what was the purpose of removing all those parts on that valley pan 🤔? Looked like keep oil to concentrate more on your lifters.. or?
That’s the solenoids that provide oil for the AFM. You don’t need them if you disable the AFM
What's AFM
@@MoDave82 active fuel management
How do you disable afm and do you keep running collapsible lifters and cam ??
If you disable the afm do you still have to mod the valley plate ?

Idk about y'all. But only vehicle besides Toyota that runs over 300k is Chevy. And we don't claim anything newer than 2007 😂

Please subscribe help us get to 1000. Thank you!
How long did it take to remove the intake? How easy was it to remove all the parts?
It only took a few minutes and it’s all pretty easy but I have mechanical experience with vehicles.
just delete the dod
After you do this you have to
Still need to get the lifter to release first and if you start it up before you delete the AFMwill the lifter go right back to being stuck?
What's dod ?
