Cam Selection 360

Ditto. No pressure on the lifter. This should easily rotate the lifter in the bore showing the cam and or lifter have the crown they should have. Once the engine is running and oil gets all over the cam and lifter, they will rotate.

As I put the lifter in, lightly oil lubed, I check to see if it spins easy by hand then the above. Once the pushrods and valve train is in, I rotate it again several times.

I know that sounded like over klll. I just skipped this step and wiped out a cam. What was to blame? Lifter rotation. Just that one lifter. All the other lifters rotated in their spot and where the wiper lobe was. Try the wipes lifter and it would not rotate in any lifter bore I tried. No I didn’t test every lifter bore with the bad lifter. I tested several lifters in the bad lifters bore.
