My passenger side is not dry but has very little oil compared to the driverside. The driverside pulls a lot of vacuum since it connects both intake manifolds.

My setup was capturing oil but apparently not enough. A good place to check if the catch-can is filtering well, is the CCV upper check valve. There shouldn't be any oil building up there. I switched to a catch-can that has a different baffle design and larger diameter hoses. Hopefully this will help.

FYI, I do hard pulls on the highway all the time so the catch-can is getting tested under high vacuum conditions.
