pressure in oil fill
 

im looking into a generation 1 rx7 and when it turns over it blows a lot of pressure and some smoke out of the oil fill i was wondering what causes this and how much trouble/cost it is to fix?

mines doing the same thing' there is a lot of pressure at the fill tube. can any one help us?

Sounds like a bad side seal, combustion gases getting into the oiling system (blow-by)

the guy that is going to rebuild my motor got mine apart and mine took out one of the bearings. so i'm going to have him rebuild it. he's selling me a set of housing that were bridge ported for $100. :MissileSm
