1) A little punctuation and capitalization goes a long way when asking for help. Adults like sentences...
2) How do you know the rear main seal failed due to crankcase pressure? How much crankcase pressure are you measuring? Are you sure a failed PCV valve isn't allowing positive pressure from the intake manifold to enter the crankcase?
3) Controlling crankcase pressure is simple and the basic concepts are universal. Create one or more large vents to allow pressure to easily escape. Adding a vaccum source to "pull" on those vents is even better yet.

A good catch can setup for starters, opening up the valve cover vents to a larger size and having a can that pulls the crankcase pressure into the intake pipe like factory works way better than those overrated cans with little filters on them that are mainly bought to look pretty under the hood. When the turbo spools, the vacuum sucks all crankcase pressure out letting the engine rev easier and drain the oil back into the pan faster.
