`91 SDL Oil Leak
 

I'm looking for this oil leak. It's been in for service and maintenance but we never seem to find it. It basically pools here in this mount and nowhere else. Here's a picture:

We don't see the source at all, save for this location:

I'm not familiar with Mercedes Diesel terminology, but we had a lot off stuff along the injectors repaired and replaced including the injector O-rings, which don't appear to be leaking any more.

Can anyone give me an idea what may be the problem or where to look.
Thanks, Mike

Thanks
 

I will check it out. Michael
