Permanent fix for lifter collapse

[Big_Kahuna]

Is anyone offering out there like permanent fix for Chevy lifter failure? I’m talking about aftermarket solid fix? 

[diyer2]

Yes

[CamGTP]

Yes.

 

Remove all AFM/DoD parts and replace them with non AFM parts. People have been doing this for over a decade. It just costs a lot of money on newer trucks to do.

What would be the cost?

[CamGTP]

I rough guess on parts is $1,200-1,300, which would be the camshaft, lifters, trays, pushrods, gaskets, bolts etc etc. Then there would be labor. I'm not sure what book time would be on it but you have to strip it down to a long block pretty much. Both cylinders heads off, have to drop the oil pan as well. So I'd say a shop is going to charge a couple grand in labor.

 

Then you have to tune the computer. That's like $700 at a minimum and I'm not sure HP Tuners has released full support for 2022's yet.

 

If you can do the labor yourself it's a lot cheaper but you also void your warranty which is obvious.

ill drive mine for a minute to see how she behave , if I like the truck I might just do that and upgrade the camshaft to , that would be wicket .

I would suggest disabling the AFM/DFM whichever your truck has. This will reduce the chance for engine failure and save you a lot of time and money. My 2021 Trail Boss 5.3L did not come with AFM/DFM because of a lack of semiconductors so I am no expert on this subject but I have heard good things about the Pulsar LT to disable these systems. Maybe someone more knowledgeable about this issue could chime in and steer you in the right direction. Remember worse case scenario Chevrolet will repair engine damage related to camshaft failure. This is a known problem on the 5.3 and 6.2L.

That will help, but he will still have lifters that fail in the first place.

I read somewhere that one cause of failure was due to the AFM/DFM and lifter interface...

For the folks that got the $50.00 rebate because your truck does not have the "chip" to make the AFM components function remember that all of those components are in your engine, just not functioning as they were designed to.

There have been and will continue to be documented failures on those components on "chipless" trucks as well as those like mine with the full bag of chips.

 

As others have mentioned there are kits to replace all of the internals with non AFM components. If I still have my truck and the lifter failure occurs out of warranty I'll spend the money on the "delete" kit. Cost will probably be lower than going with OEM parts that are failure prone and labor is what it is.

Check out Texas Speed, they seem to be the one most use.

Hi, so dealing with collapsed lifters and camshaft failure now on my ‘19 with 83k miles. You stated that Chevrolet will repair engine damage related to a camshaft failure. Can you elaborate on that? Are they doing that on vehicles that are not under the 60k powertrain warranty? Would rather have the dealer fix this, but the cost for an engine is crazy. Leaning towards going to a local shop to have them delete the AFM and repair lifters and cam. Thanks!

They will repair engine damage if the vehicle is still under warranty.  Your vehicle is well past the warranty stage so you will absorb all of the costs for any repairs associated with your engine.
 

I swapped out my lifters and pushrods, and my costs for lifters, pushrods, trays, gaskets, fluids, etc. was close to $2k in parts alone.  Based on the allotted time to replace those components, I would guess anywhere between $3K-$4K in labor.  If they need to pull the camshaft because of damaged lobes, add another $1K.  From what I remember, most people are looking at $6K-$8K for lifters and cam replacement.  Compare that to $6K for a brand new crate motor, and you are probably better off getting a brand new crate motor and paying a couple grand to get it installed.   Since I have 130K+ miles, if my engine ever experiences a lifter failure, I'll be replacing the entire engine.

You quoted me from over two years ago. Chevrolet will not repair lifter failure out of warranty and at 83000 you are out of warranty. Gangly is correct. Your best bet may be an engine replacement.

depends on his powertrain warranty... mine was 5/100,000. My lifters went out at 79K.
