16v: how do i keep oil from flooding the distributor?

[SequoiaGLX at twcny.rr.com (SequoiaGLX@twcny.rr.com)]

I was telling David that my '97 VR6 factory pump had
some sort of aluminum looking casting for an impeller.

Corrosion is not an issue as long as the coolant is
kept reasonably fresh, this is obviously why coolant
changes are an issue.  Good coolant contains
corrosion inhibitors.  If you think about it, bad
coolant would rust a steel impeller no more than it
would the iron block, etc.
