Comp R lifter failure? anyone had comp r lifter failure yet? We had preload set perfect. I pulled engine due to oil pressure problem. (It started losing oil pressure WOT) When I pulled the heads we noticed 3 of the lifters the cups were not clipped in any more.Like the clip had come out.

yeah they have
I have always had some valve train noise Have went over the lash more than once. Heck I have had it double and triple checked by others also. So the lash was not the problem.

Yup, I had one Comp-R fail on me in similar manner. Mine made no noise, I just found the two broken pieces of the stamped-steel plunger retainer stuck to my oil pan magnet while doing a routine oil change.
Comp Cams was very cool about it, swapped the entire set on warranty even though only one had failed.
They were easy to swap in my old L98 engine, no head pulling required.

The two pieces were roughly U-shaped, stamped steel.

I would like to see a picture as well. I found a single U shaped peice of metal on the drain plug. Car seem to run fine but this is nagging at me. I have 977 springs and Comp R lifters. I am half tempted to dump th lifters and springs this winter for peice of mind.
