I recently overhauled my narrow deck O-320D2A. I installed EFII ignitions when i installed the engine in my RV7. The engine had 741 hours on it and was built in 1982 by Mattituck. Since the tach shaft had some wear at the seal area and the cross pin was worn, i elected not to reinstall them. RPM is off the ignition system. It is a two piece cam. I did not attempt to block-off any oil flow down the cam either. Now i have a little oil coming out the overflow. I really don't want to remove the engine, remove the accessory case and reinstall the tach shaft, or a seal plug. the oil slinger is in place. Could i make some sort of a cover for the overflow fitting that would vent the crankcase, but prevent oil from being thrown up the fitting?
