hey again 1981 240d less than 100k i have some blow by. from the oil filler hole. what is normal/acceptable? the car sat for years and i read somewheres on this forum that this can casue sticky rings. engine has power and i even go out on the cold 27 degree mornings here in north carolina and the car fires up with out a hitch. the oil cap dances pretty good when it runs. very little engine smoke too just a very light black smoke on start up . hardly visable. the amount of power this little monster has on the road makes me wonder what all the other 240d owners are griping about. so ... anyone else have blow-by on their little 2.4? i and checking out a 300d with 175k on the odometer and ther is zero blow by. the oil cap does not even shimmy in the slightest when it runs. so i am confused. thanks Aaron
