yes- Its the #5, the 14 part of it looks new. It appears to be leaking out from the connection to the engine. Lots of fun. From what I can gather from my MB CDRom I have to take the intake off.
I may be able to get at it with the intake off, if not the oil filter hosing will have to be removed also.

The engine side of the hose is covered in antifreeze, I hope this is what is leaking. I can not see enough to know for sure.

I am going to have to tackle this next weekend, car is on garage rest until then. Any tips on removing the intake?
