I have observed a leak from my rear main seal. The leak is occurring ,not at the seal split line, but at the bottom 6 o'clock position. Currently using a Fel Pro 2090 seal.

I've pulled the seal and it does not look worn or damaged.

Is there a way to shim between the seal to tighten the clearance to the crank? Is there a better SBC main seal to use?

Is there a tool to locate the 2pc rear main seal adaptor on the crank that I should be using?

Any other tricks to stop the leak?

Thanks in advance for the advice.
