1981 MB 300SD

I have a 1981MB 300SD diesel.

It is an awesome car and I'm loving it. I've noticed an oil leak at the front of the engine in what looks like a tube that comes up from the oil pan. I found a thread on this forum before about it and it tells which parts to replace and how to do it etc, but I cannot seem to find the thread again.

It's leaking oil like crazy and I want to get it fixed so I don't have any issues or chance blowing the engine.

Does anyone know where I could buy the parts form and what the parts would be? Or by chance happen to have the link to the thread I'm talking about?

You will need to remove the pan to do it right. Get a new pan gasket, turbo tube o-rings, and the rubber bushing. Ideally you'd replace the lower section of tubing also. It is not really an "easy" job at all. If you are not confident in doing potentially complicated/difficult mechanic work, I'd take it to a decent MB shop and have them replace it. I had mine start leaking badly, and I was losing about 1.5 quarts a WEEK.

Is this what you are talking about?

Look in the buy parts tab above for parts.

there were three HP ratings on the OM616...

1) Not much power
2) Even less power
3) Not nearly enough power!! 240D w/auto

Anyone that thinks a 240D is slow drives too fast.

80 240D Naturally Exasperated, 4-Spd 388k DD 150mph spedo 3:58 Diff

We are advised to NOT judge ALL Muslims by the actions of a few lunatics, but we are encouraged to judge ALL gun owners by the actions of a few lunatics. Funny how that works
