I'm curious if anyone can provide specific information on our engines in regards to solutions regarding the PCV system in our cars.
Most people seem to place a catch can on the passenger side and leave the driver side breather hose alone or put a filter on the valve cover. My thoughts tell me that seems backward. The driver side is the intake breather side which is in vacuum under full throttle loads which is when I'd assume most of the blow-by is occurring. Wouldn't you want the catch can on that side before putting one on the passenger side?
