AFM. That's what eats these trucks up.

There's a couple of service bulletins. PIP4492A was one of them.

Involves replacing the left valve cover or cleaning a baffle.

Another was cleaning the tops of the pistons with a seafoam equivalent then putting a shield P/N 12639759 before re-installing the AFM module.

Supposedly these helped but I agree. AFM is junk.

Just add oil and keep driving. My wifes 07 Yukon burns about a quart between oil changes. My 08 doesn't burn any. I knew about the issue before buying hers, and it has never affected anything, just have to keep an eye on it and make sure it's topped off.
