Check this out? The intake rocker shafts have a
bolt that runs through them that doesn't allow it to move. The
exhaust has dowel pins that hold them from moving. Those dowel
pins were broken off. The rear exhaust shaft was protruded
out. Oil is delivered through that shaft to the lifters. When
the shaft moves or rotates, the holes don't line up anymore
and the lifters get starved for oil.
The fix is to replace the rocker shafts, the rockers (which
include the lifters) and a pedestal kit. Fairly easy repair.
