I once had a push rod with a cracked cup. Looked normal except for a
hairline crack. When the push rod was pushed up against the rocker arm
ball, the cup would open up widening the effective tappet adjustment.
The valve would make noise under some engine conditions and not make
noise under others. I thought I had a small end rod problem until I
just happened to glance at the push rod in the right light and with the
hairline facing me.
Either way, it never hurts to roll all the push rods to make sure they
are all straight.
