The WSM shows a Oil-Water Heat Exchanger attaching to the passenger (left from seat) side of the front sump cover. Perhaps the gasket has started leaking or one of the lines has come loose or become damaged?

If the oil is coming from the pulley area it's likely the front main seal but they seldom gush like that without leaking by drips for a long time.

I'm sure there's better images but I was looking at 300D 605_606\01.7500 which is Removal/Installing the Oil Sump. But there's likely better images of the lower sump/lower engine.

Subject: [MBZ] E300D troubles continue

Lately I seem to be fighting a never ending battle with this car.
Finally the lost shipment from Rusty arrived and I fixed the air leak in the
fuel system (fuel line seals and a new manual shut-off valve).
While I was waiting for the injection system to purge and the motor smoothed
out (~10 min.), there was a big puddle of oil under the car.
The bottom of the oil pan was covered with clean oil (last change at 3,000
miles ago). I wiped off as much as possible and it stayed dry.
As soon as I started the motor, oil started to run down the drivers side of
the oil pan, ca. 2 inches in front of the drain plug - a drop every 5
I doubt it to be the pan gasket (leaks only when the motor is running).
Any ideas where I need to be looking?
TIA and happy Thanksgiving.
