New to Mercedes, I am working on a 240D diesel. Looks like front sel is leaking oil. Is this hard to change? Thanks for any comments.

 

diesels leak.....just add oil.... I live by 2 quarts every 1000mi on old 4 and 5 cylinders is ok. If you can't deal you will have to pull the crank pully to replace....not a good time, plus who knows what else you will find....good luck..
