I installed breather tank on both sides of truck after 100 miles only the one on the passenger side has oil here are the pictures. The driver side isn't the problem the passenger side is. To much suction from the supercharger.

 

 

Kind of strange isn't it? I too have noticed nothing coming out of the DS camcover but lots out the passenger side. This is with the "straw" disconnected and plugged from the air inlet boot.
