*** IN STOCK SHIPS TODAY *** RCD/P&P oil tank/supply .625" line check valve assm. This check valve can be installed on the supply line from the oil tank so in the case of a engine failure this valve will close not allowing all the containments into the oil tank.
This valve simply has a spring loaded block off plate that if reverse pressure comes into effect it shuts allowing the rest of your oiling system to keep clean.
This valve is simple to install and the flow goes towards the buttonhead bolts.
