Thanks Benzmac! I thought that might have been the problem (too much fluid), but it's hard to determine the level (for me anyway!?). Anyway, I took it into Tucson Mercedes-Benz and had the man change the fluid and filter. And sure enough, the fluid level was too high, and that was the problem. I went ahead and had him change the fluid and filter anyway ($125.00). He also told me that nothing was harmed and not a problem.
Anyway, I asked him about the head gasket leaking. He said from what he could see (under the car), it didn't look like the head gasket had a leak. He said there was some oil towards the front of the engine that could be from the 'front cover of the cylinder head(not sure if it was 'head).' So I'm not sure, does this sound like a common leak for the front of the engine? He said it wasn't all that common, but that he had seen it quite a few times.
Thanks again everyone!
