Question about Cars & Trucks
Cap keeps blowing off
Too much crankcase pressure for some reason? I've seen a melted piston cause so much crankcase pressure, it blew the pcv valve out of the valve cover and sprayed oil all over the engine compartment.
Is your oil cap threaded? If it is threaded, I don't think I've seen one of them blow off? Also, check crankcase ventilation system, pcv where applicable. Do you have a lot of blow-by from crankcase? I don't know your year--make--model or engine size?
