Been chasing a frequent but random pop/sneeze on her for the last few months. After starting with the simple stuff, and not finding the problem, I started digging deeper.
Found this last weekend...
What made it really fun was when I went to pull the lifter (#7-exhaust), the cup fell off and dropped into the oil drainback hole in the lifter valley...
Swish! no rim, all net... well Fuck
Had to pull the pan too :
Picked up these Tuesday, along with the intake gaskets. Waiting on the special order pan gasket.
I discovered some galling on one of the rocker rollers, and coupled with a rocker failure a while back, I decided to replace the rocker set as well.
