I have a 190e 2.6 manual with the same M103 engine found in the 260e and 300e 2.6. No idea about engine wear but 79C (174F) is not an unreasonable operating temperature. I'm more worried about the 100C + spikes these engines seem to have in hot weather and slow traffic. I've read too many blown head gaskets and overheating stories to allow my engine to get into that temperature range. If the temperature was getting stuck at or below 60C, then I would worry about engine wear.
cheers
Justin
