So replaced old valve cover gaskets because they were leaking. Helped with oil consumption but..... I always replace pcv valve when changing oil and when replaced the manifold gasket common body was full of it! The tube from the pcv to the intake was caked as well. Cleaned out the tubing and the manifold and put in another new pcv valve. Ran for two weeks and tube and intake were once again caked with oil. Is there anything else that could be causing raised crankcase pressure causing massive amount of oil to be pushed up into intake? Any thoughts??
