My buddy needs help with his fox body stang. In his words.

I have recently installed a crankcase evac pump on my 91 GT. I can't keep the catch can from spraying oil when it's not even full. I have had the pump suction tube installed on the valve cover, the back of the intake, and even had a custom baffle system made on the bottom side of the intake so it wouldn't suck oil anymore, and it is still is doing the same thing. I am running a motorsport evac pump and I have a moroso check valve set at 6 inch pounds at idle. I thought this custom baffle system on the bottom of the intake would work, but something is not right. I have the moroso catch can mounted on the frame rail about a foot from the pump, and overflows when not even full.

 

This might sound stupid, but is he sure the connections on the catch can aren't reversed?
