Well the problem smoke is still happening, and more often - about once a day now. As before, the exhaust is normally smoke-free. Just at times, after taking a fast turn or going down a hill, it makes big embarrassing trails of smoke for about a minute, then clears up. It doesn't make much difference if I put it in neutral going down hill. If anyone knows the internals of this engine, is there some place where oil could be collecting and then "spilling over" into the intake, or getting sucked in somehow?
