I saw white smoke blowing out of the breather cover vent hole, so I took breather cover off down to reed and left the inside cover on, I turned the engine over with the inside plate still on and as soon as it started turning over there was oil comming out from the little bottom hole on the inside breather plate. Why is oil comming out from the breather plate?? The fuel pump, bottom of outside breather plate and all along the engine below the breather plate is covered in oil / dust. Is oil getting past the piston and then down into the valves and valve guides? What is my next step, I did rebuild the engine last summer but did not have it bored to 1 over. I know what the answer is (take engine out and redo it again) but I was hoping to delay as long as I can. Any help greatly apreciated.
