First I would pull the vent off the valve cover with the engine running and of course fresh oil in it! If you hear and feel a ton of air flowing out of there you most likely have bad valve seals! Where gas flows so will air. Next of course check the fuel regulator by pulling the vacuum line on it and make sure no gas is pouring out of it. That leads back to the intake and through the same rubber hoses that go back to the valve cover vent on my M102 motor and I guess could flow back into the valve cover. Last is the big one and the most likely problem, that the rings on the pistons have lined up and the gas is going straight to the oil pan! That would mean removing the head and checking the rings for alignment. It happens unfortunatelly and of course means new rings! Good Luck!
