Has anybody done this? I have seen a few threads about people wanting to do it, but no info on if it was successful or not. My thought was to delete the valve, block the vacuum port on the intake manifold, and on the hard vacuum line that runs back to the tank, run a vacuum line down under the car to vent fumes away from engine bay. Does anyone know if this would work? It sure would clean the passenger cylinder head area for a better look.
