Review on Enhance Engine Performance with Fel-Pro BS 40634 Rear Main Seal Set by Adam Quintana

Revainrating 1 out of 5

Great print! As expected from a Fel-Pro

The rear oil seal fits my Miata 91 perfectly and sits tight on the rear crank. It is identical if not better than the OEM part. I haven't messed with the gasket, however, but so far I have no leaks or oil level issues to mention.

Pros
  • Nice little thing
Cons
  • Weight
