Ruh Roh.....

This may be more than you think. My '89 100Q had this, thought it
might just be the gasket. No..... Turns out that these cars have a
problem with the oil pump, which sits in that corner of the pan.
It looks like a gasket leak, but is in fact the pump weeping out
the side where it meets the gasket.

The cost was pretty high: $600 something for the pump alone....
I lived with it for almost 2 years before I bit the bullet.
