The gears that drive the oil pump!
One is toward the rear of the camshaft and the other is part of the oil pump
drive that mounts in the block.
With high oil pressures, these can soon become razor edged from wear.
There are harder replacements from some Japanese engines, but the point it
that high oil pressures aren't really necessary anyway, as what you need is a
high volume (which the modified pump takes care of). The old saw about 10-15
psi per thousand rpm is no longer in vogue.
