ok guys....
first off i don't drive the 560sel (88 model)
secondly when i went home from work this last time i re-created the smoking scenario by parking on an incline and letting it go in idle for about 10 minutes....sure enought billowing white smoke
the queen is driving the car in san antonio, tx and i guess when i get the update then you all will know as much as i do....i am 400 miles from the car so that's why i am posting all the time....
as far as the engine operation, it runs like a top....eats a lot of gas(comparative to my 1987 420sel with a 4.2 liter v-8)
but there doesn't seem to be anything out of the ordinary other than this thing i have yet to solve....
