Its the 657X engines inner crank seals leaking. Most older doo's leak some, especially
when stored awhile. It (oil) can be spun out if *plugs removed (oil hydrolocked crank) and run til all is burnt out, then continue to run without Smoking. Its when
the smokeing gets bad, its really ready for overhaulin. Bills86e
I pincher my oil lines when I store my older doo's.
