I've been getting some oil in my intake and I'm almost positive it's coming from the PCV (well hopefully anyway). My question is, can I plug off the PCV and just put a breather cap on the oil fill neck? Will this allow for enough ventilation?
Dont plug the PCV in the back of the intake, plug the nipple on the filler neck and slip the hose back over it. You can just use a piece of electric tape to put over the nipple then slip the hose back on. After that you can toss the breather in place of the oil cap.
How about just plugging it with a breather for a couple miles, just to see if I'm still getting oil in the intake? Cause then if I still am the oil is coming from something else; i.e bad valve seat, bad piston rings
