This is the rocker arm that I pressed the bearing out of to compare needle size. This is the same as the other 15 rocker arms in the engine as well as the same as the one rocker I purchased new at the dealer to replace the one shown in picture.

 

pulled out the lifters and cut apart...bearings in Lifters and rockers different than what I found.

roller on top is what I found, on bottom is the lifter roller.



Again, on top roller found, on bottom roller from rocker arm assy.



Any other ideas?

 

Weird. Oil pump bearing? I don't know what type they use so that's just a WILD guess.

 

put a lifter beside it.....


My oil pump bearings are so small you can't even see them

 

I've talked to alot of people and the general answer I am getting is the same as here. The 4 pieces are not anything from this motor. The guys at thunder said not to worry about it. That will be tough to do, but after I get the new cam and lifters installed, I should know soon if theres still a problem.
