M_Boats: 4-stroke outboard crankcase oil--close the valves!

Earlier discussions show occasional problems with crankcase oil leaking out of the engine or into the combustion chamber. It is important to store/transport the engine in the correct position, but an added precaution is to slowly crank the engine until it comes up against compression. That closes both the intake and exhaust valves and helps keep stuff like oil and water out of the combustion chamber. --Gary Hyde Pullman, WA gmhyde1@mac.com M17 #637 'Hydeaway 2' "...There's nothing quite like messing about in boats..."
