Why does my Chevy GMC lifter keep ticking?
Listen to that dead lifter. Its common to hear your lifters ticking on a early morning cold start with these trucks that goes away after a few seconds. The real problem happens when it doesn’t go away. You may still be in luck though with just a quick cleaning. This truck is too late and the damage is already done.
What causes a lifter to collapse in 4 cylinder mode?
(Frame rusted away) The failure is when it tries to come out of 4 cylinder mode, the lifter stays collapsed and won’t return. If you disable DOD, it won’t collapse ever again. Only other failure type after that would be the roller itself or the lifter has dirt stuck in it and has a slight tick but will still run.

Why is cylinder 6 on my Chevy Tahoe not compressing?
So, it could be bad lifters causing the compression issue or a fault in the AFM assembly causing an internal oil leak/bypass to the AFM lifters to clyinder 6 and causing them to partially collapse and drop compression. If it’s bad rings on cylinder 6, then there are bigger issues here. Suggestions to look at.
