Want -

It's your car and no one has the right to tell you what to do with it. However, you need to understand that you are taking a gamble and that it could be a really big one. If it were me, I would find a used cooler and new lines and do the repair fairly soon. Either that or quit driving it until I had the time/inclination to fix it. My personal feeling is that MB put that cooler on for a very good reason. Most people aren't aware how large a part the oil plays in cooling our diesels.

The responses to this thread are really good ones from guys who care. It's still your call however.

just my $.02,
