excessive 340 crankcase pressure

What is so hard about understanding this? Simple principle, fresh air in one side and regulated suck on the other. If anyone has an issue then put in a draft tube like the really old engines. Cummins used this into the 2k range on the 5.9 killer diesels! This issue has been beat to death and few learn.

Regulated suck. Sounds like a girl I knew in school.
