Hi, I have a 1968 Rocket 3 that is wet-sumping that upon a no-use time, some oil is draining through the oil pump and by passing the non-return valve to the sump. Apparently, if the non-return valve is not seating properly, then this can occur. It causes a starting issue and sometimes oils the plugs, but often will disappear upon travel. Now, I have a 1969 workshop manual that shows the non-return valve and the pressure control valve accessible from the outside of the engine. Mine is 1968 and neither valves are present as per 1969 illustrations.
So, where are they? Perhaps internally - can anyone assist?
