You got an intake that won't seal cause the block and possibly heads have been shaved but the intake hasn't been cut to fit the changed angles.
You got a road draft tube hooked to the aircleaner that's putting oil into the cleaner.
You got a pcv on the oil fill tube but it's not connected right now.
You got high crankcase pressure pushing oil into your cleaner and into the intake ports cause of the mismatched sealing surface.
It's a no brainer!
Cut the intake to fit the angles and get your pcv set up right.
Burn us off a pic of your set up!!
