I was looking through engine pics on here and it seems quite a few of you have opted to go with a breather on that valve cover instead of running the pcv valve. Does it hurt anything to remove it?
On any engine, you will get some blow-by past the rings. This blow-by is fuel vapors and exhaust fumes. Those vapors/fumes go past the rings during the compression and exhaust strokes. If these vapors aren't removed, they will churn in with the oil, and degredate the oil quickly.I don't guess I really understand what a pcv valve does exactly
