[BRENT in 10-uh-C]

Let's start by asking why do you need an aftermarket rear seal? What are you doing that requires one? Are you pressurizing the rear main? None of the options available are really geared towards the hobbyists, and there will be machine work involved such as machining the slinger from the crankshaft. If you use the Terry Burtz seal, then you need to be able to adjust the thrust (-again, machine work by the machinist) to set the proper thrust. I would pose the question to your engine machinist first, asking what he has been successful using.


As an engine rebuilder myself, I have had several failures of a type that Snyders sold and have now gone back to the stock slinger method.
