Larry,
How much oil pressure does your buddy have? If the oil pump is not
developing sufficient pressure, the valve train suffers. If the oil pump is
OK, then I would suspect either a flaw in the engine block casting itself,
or that something has fallen down into the oil line that feeds the head.
I'm not familiar enough with the engine to describe where the line is, but
it shouldn't take to much hunting around the head with a flashlight to find
it. Fixing this problem would be tedious, though. For example, I believe
that the oil line feeds the rocker assembly through the pedestal itself. So
you could remove the rocker assembly and then try to force a stiff wire down
the oil line, forcing the blockage down. But I believe you'd just be
pushing the blockage down into the pump itself, which IMHO is not a good
idea. Rather, I think you'd want to lift the car, drop the pan, pull the
pump, and then push your stiff wire up from the bottom, forcing the blockage
up and out the top of the head (obviously requires removing the rocker
assembly).
Have not BTDT, but it's a direction for your friend to begin further
exploration...
Best regards,
Kevin Riggs
