Thanks for the info.
That is pretty pathetic warranty work done under warranty.
I am going to write MBUSA about this as my situation is very close to what you described.
The head gasket and seals were replaced at 48kmi in 8/2000. The warranty on the car expired on 3/2001.
Now at 59k (or about 10kmi later), the thing starts seeping again as the area is a litle damp.
