Took the valve body apart and there are 2 paper gasket and one metal spacer. Found the company was definitely in there during the rebuild. The two paper gasket are identical except in one spot.... Near the breather. They were flipped and it was allowing a small amount of oil to blow by into the breather port. They also used a die grinder to clean off the old gasket leaving deep swirls in the sealing surfaces and spacer.

Fixed and gone. Always take a look for yourself and don't take someone else's word for it.
