Hi. When I start the engine, white smoke comes from vent tube on top of valve cover leading into airbox to throttle body. Also oil filling spark plug wells, airbox and throttle body. Engine sputters and doesnt smoke from exhaust. Just replaced valve cover gasket. What could be wrong.

Have the engine checked for blowby, your compression may be low an dleaking past the rings into crankcase.
