Hello, i am doing a service on a 1916 Continental engine for a customer. This is a 303cid inline 6. I got the engine dismantled and now we are trying to figure out oil routing in front of engine. I have heard that there is a regulator/restrictor for reducing oil to front camshaft bearing and intermediate shaft bearing. Anyone have schematics or experience with this engine? In picture i have pointed oil supply line coming into front of engine and small oil reservoir feeding Camshaft and IMS. Paul
