Old air filter used with the turbo valve cover, stock turbo PCV system is used. 2000miles or so. This filter been outside the car a while and put next to grease parts but you can see where the filter is soaked with oil.




Old air filter used with the TBI valve cover and oil splash guard, 1500miles or so. NO oil catch can is used!!! One nipple for the PCV and one for the fresh air let that connects to the airbox.




Oil free air TII box. Don't mind the debris, that's why the air filter is there!




Under the hood pictures.




TBI valve cover and its oil splash guard is great mod to prevent oil all over the valve cover, air box, engine bay, and on top of the transmission. Don't even need a oil catch can.
