Default PCV routing, crankcase pressure

Ok so I have seen a million different ways on doing setups, just curious to what people may be doing with the components I'm using! I have a fresh built motor and I'm getting a lot of crankcase pressure causing oil to seep at WOT under a load occasionally....

Ls6 engine
I have a LS1 valley cover to clear the LSX intake

-Open port on passenger side valve cover towards the front

-Open port on driver side valve cover towards the rear

-LSX 102 intake with port on passenger side
-Throttle body does not have any ports accessible

How would you guys route your system to relieve some crank case pressure!

Thanks!

Front port passenger side cover to throttle body.

Rear drivers side port and rear passenger side port to Y fitting to catch can to passenger side intake manifold port.

Air will flow from throttle to valve cover, out both valve covers to catch can to intake manifold

My throttle body does not have a port, and valver covers only have one port per cover!

Im thinking im going to

driver rear valve cover to catch can, after catch can im going to do a inline PCV valve into intake

and on passenger valver cover put a fresh air filter adapter on the oil fill hole!

That's the next thing to do. Take a look at the Mighty Mouse catch can with the integrated PCV. Bit pricier than other options, but they guarantee your intake will not see any oil.
