Hey I'm new to this forum and new to working on carsa but have a general understanding. I own a 1970 Nova with a 454. When i bought the car it leaked a little oil out of the passenger side valve cover but not much at all. I just bought new valve covers and it suddenly got worse. i then tried different gaskets. Now it's pouring out oil so much i not sure it is even from the valve covers. Any ideas on where it might be coming from? or things i might need to check? thanks
