440 w/TorqStorm SC - Boost Getting Into Crankcase?? Valley Pan BULGE

Yea if the the breathers are up to the task the only way it can get in is the rings or head gaskets. Are you using a stamped steel valley pan? Maybe once it bowed there was no sealing it.

The head gaskets were fine. The ring seal was excellent. Leak down was 3%. Maybe a different style of breather would help? Open element breathers?
