Bonjour,

I am the new proud owner of a 1985 Mercedes 300 SD turbodiesel. After driving about 1150 miles over two weeks, the car began marking his territory with prestone and sometimes (depending on the day) oil. I am having trouble locating the leak in my engine after a rough cleaning (I didnt use a pressure machine). It seems it is coming from the front end of the passenger side, probably next to the radiator; but that area *seems* pretty dry. I have no clue of where it could be after 3 hours of searching on google. By the way, it doesn't burn oil or anything; there is no harsh smell when driving. This only occur when the Mercs is parked.

Any ideas of what are the most common leaks on this model?

My guess is the oil pan gasket and some hoses that needs to be changed.

Thanks.
