rear main leak

Is it possible that you need to vent your crank case pressure better? I say that because my stroker is experiencing this, and I have narrowed the issue down to needing to install some type of vac system on the crank case. I have been running vents to a puke tank, and they arent doing enough.

Just a thought.

running a vacuum is the answer to many oil leaks . I have my 2 vacuum ports on my 1200 cfm throttle body hooked up to a valve then to an oil catch devise , and to the pass side valve cover, the valve was an experiment to control how much vacuum I run , got it patially closed /running around 11 inches , and not sucking any oil , but have no leaks !
also run a pan evac set up on the drivers side cover ,it will help at hi exhaust flow / works for my 505'' fish...pic is before I installed it ...
