premium Felpro seal
Hi,
I used the seal that came with my FelPro bottom end kit. Following "best practices" and a few simple steps in the installation of the rear main, should be all that's necessary. Even a premium seal can be "hosed up", if not installed properly.
Think a couple of tips:
Clean mating surfaces
Offset parting with seal lip in the proper direction
A "light" smear of Hylomar on the mating machined surfaces
Happy Motoring!
