While it was out I would see if anyone near you could machine the block to accept a one-piece rear main seal. Also, I would buy a harmonic balancer repair sleeve and install it. Even if you center that seal perfectly and polish the balancer sleeve nicely, it can still leak. One other thing...if you're handy with metal working (1/8 inch aluminum will do) make a bar for the lower side of the pushrod cover so it will seal better.

Good luck,
Jon
