My 300D is my daily driver, probably put on 60 - 70 miles a day. I've had an oil leak for some time, it seems to come down, right behind the oil pan, and leaves a half-dollar to silver-dollar sized stain whenever I park for the day. I'm guessing it may be the seal between the transmission and the engine. Likely more than one leak. The valve cover gasket was recently replaced, so probably not the culprit.

Anyway, today, I got under the car and saw that WOW, much of the underbelly is pretty much coated with oily gunk. Even much of the exhaust. I guess that all helps protect from corrosion. Though not a rocket scientist, I'm assuming this is an effect of driving with an oil leak over time.

My oil consumption doesn't seem too bad. Maybe a quart every 3k miles. So other than the mess on my asphalt driveway, how urgent is it to fix? If it is the main seal, I'm assuming $$ expensive labor.

Thanks,

Chuck
