I would suggest he do a compression check of his engine. Correct
compression is about 150 - 175 psi during cranking with the throttles wide open, but
more important is that variation between any two cylinders should not be more
than 10 - 15 psi.
I have experienced something very similar with my BJ8 several years ago. It
turned out to be pieces missing from the top of the piston, at the edges.
Apparently, the pieces would rattle around in the cylinder until they exited
the exhaust valve. If this is the guy's problem, it should show up on a
compression check, and he can verify it by pulling the head. In my car, I did not
notice any problems with the way the engine was running, but I had the
sudden, rattling sound that would end quickly, but the last time it went on for a
mile or more.
Happy Healeying!
