You can cut the hose connecting the valve cover and the PCV and put a large bolt and clamp in the end that connects to the PCV side to block it off. The car will run fine with the other end open to atmosphere although you will get a little condensation out of it while the motor is warming up. There will be positive pressure blowing out the hose on the valve cover side. If it is connected to the PCV that creates a slight negative pressure in the valve cover so that when you take off the oil fill cap it has slight suction but once the cap is off it will blow air out the hole. |
