Funny, that was going to be my next step.  I went to
the junkyard to find a cap that was in good shape, but
many of them were not much better.  I know your not
supposed to mix them, but I know they are all pretty
close, right now I figure the smoother the better.

As far as the cause, I've been thinking, it could be
from oil starvation.  It is the furthest away from the
pump, and I know the pressure will drop to 1.5-2bar
when I really hammer it in first gear, and the oil is
not perfectly topped off.  That reminds me about the
Accusump that I was going to install.  It never ends....
