Oil Leak (or Big Surprise!)

[Dave Hiley <dhiley@cadvision.com>]

Hello:

So my new rebuild is not perfect.  It leaks oil.  OK y'all stop laughing
now.  I thought mine and only mine would be different than anybody elses.
Yes, it is the rear "seal".  About 3 tablespoons per outing are left on my
previously virginal garage floor.

Question:  I was told today about a rear "seal" conversion from Britain
that is used on Spridget race cars there (and maybe here too).  Anybody had
any experience with this?

TIA
