I am experiencing oil leaks under boost and am assuming it's due to excessive crank case pressure. I have the Mighty Mouse PCV catch can set up per this diagram
Would adding a breather on my oil cap help this issue? Thanks
Tried plugging the manifold ports and leaving the valve covers open to atmosphere during a spirited test drive? Quick way to see if it's the can or not.
Spoke with Mighty Mouse and it sounds like my fittings on catch can are only good up to 600 crank hp. Im going to get bigger fittings and maybe run a line from oil cap to can also to help out.
