JonetteP Posted March 23, 2002 Share Posted March 23, 2002 Hi Arlen, I would check the valve cover. If the plate inside the valve cover does not float easily, it will hang up an allow the engine to suck oil into the intake. If you notice a lot of oil in the carb inlet this is most likely the problem. Hope this helps. Neal Pierce Link to comment Share on other sites More sharing options...
