Back in Dec, I was driving down the road, all of a sudden it was hard to accelerate, sluggish, and check engine light. Got home pulled codes...knock sensor codes...well I got that code because after pulling pass side valve cover found bent pushrod for #4 cylinder. Replaced all 4 afm lifters, and new pushrod.
All good for 6600 miles. I noticed a ticking noise last Wednesday, drove home, no check engine light, and ran fine other than the ticking noise. Pulled valve cover on pass side...same exact pushrod is bent again...
I'm a chevy all day long, but damn. I'm getting tired of putting money into this turd. Only 87k on this 2015. Any suggestions on why the same location of pushrod would bend. I am a mechanic of 33 yrs, so I have taken everything in to consideration. Possible intermittent lifter oil manifold?
