Another month and another problem to be resolved. Here goes: The 2001 Passat 1.8T has had a hard life in the past year. The specifics are listed in previous posts. Most recently, the radiator was replaced because the engine was overheating again. The car has been leaking fluid ever since but it is not radiator fluid. Yesterday, I took a look at the oil and found tan gunk mixed in with the oil. I must admit that I had concerns after the fact about the shop that did the last oil change. Is it possible for mechanic to screw up the head gasket while replacing the radiator? It was fine before the repair. Is there another source to look for the seepage into the oil? Basically, the question is - Is the car destined for the graveyard because of this?
