Seems to smoke when the engine is under load smokes, and not it doesn't. Almost seams like a ring issue. That is the only part I can think of that gets loaded and controls oil consumption. I wonder if you have a worn ring groove, broken ring etc. I think I'd start with a compression check and possibly a borescope looking for piston wall issues. Just to rule that out. Be a shame to rip apart the top end only to find it was the bottom end.
380SL Blue Smoke
Is there any plausible reason why my '82 380SL emits some blue smoke in "D" at idle on the roadway and emits the little more blue smoke on take-off - and then disappears - (which seems indicative of worn seals or guides) - but refuses to do the same thing idling in "P" or "N" in my driveway. No smoke at all at idele or when giving it some gas.
Could there be some weird vacuum issue happening? The cam oilers are firmly in place, the valve cover gaskets are fresh, and the crankcase ventilation hoses are OK and are properly attached. It is definitely motor oil and not transmission fluid.
