L99 lifter tick

[alexsholly]

So just notice the lifter tick or piston slap on cold start up it does car away but just curious if I should be concerned and since my car is not under warranty if gm would fix the issue since it is a problem with the afm lifters being faulty I would prefer to not have to pay out of pocket for this since it is a common issue that gm knows about

Outa warranty...outa luck....unless you researched it back in the day,you would have never known there was a TSB....Chevrolet sure didn't broadcast it. Untold numbers never knew or was told...its normal. in your favor, it's not catostrophic

I'm just worried about doing any kind of damage to my engine only had car for two months so every little noise worries me lol

My '10 SS L99 has never made a lifter noise. Make sure you change your oil OFTEN.
I've done 16 oil changes in 10 years. Like Hunter 1660 says any lifter noise should
not be a problem. Again, keep your engine oil clean and you should be OK imo. My
SS just turned 60,000 miles.

There was a TSB, and no, you're no longer covered under warranty.

This was a "feature" on millions of GM engines with a faulty AFM lifter design. There's an upgrade that you can have installed, but it will cost you over $2,000.

I can't attest to the longevity of engines without the fix, because I had mine replaced under warranty years ago.

If you're not trying to spend a bunch of money on it too soon you can try to add some Lucas heavy duty oil stabilizer during the oil change and it helps a lot with lifter noise. It's not a fix but a temporary patch
