This one really threw me for a loop. Once my 1985 300TD gets halfway warmed up, a sickly sweet soooty smell emanates through the vents - even with the ACC in the "off" position. At the tech session last Saturday, Ed (the tech I was working with) pointed out several possible sources: a dribble of green antifreeze coating the large radiator hose that heads downward and to the left (viewed from the front), and other areas.
We tightened the radiator hose clamp, which seemed to solve that issue. Ed pointed out as well an awful lot of oil coating the engine, basically from beneath the turbo to the bottom of the oil pan, as well as oil seeping fom the breather hose on top of the valve cover and the valve cover gasket itself (despite being new). I was instructed to clean off as much of this gunk as possilbe and then inspect for any live leaks. I cleaned up all the areas that were accessible, but it's still too early to tell whether there is an active oil leak associated with the turbo assembly. The antifreeze flow has been stopped so while I am hoping this takes care of smell problem my pessimist self says the turbo itself could be the source of the toasty burnt smell. Anyone been there/done that?
