I 'managed' to get all the old parts back from the dealer that did the job this week, and needless to say, they are quite eye opening. I cant really say I agree with 'Mercedes' take that this is a "normal" noise, which is what they have brainwashed they're dealer network into telling the customers when they complain about the thumping noise on startups. 1 set of crank bearings (upper and lower set) are so scored, you cant run your finger nail across it without it getting stopped in the worn groove. I will let the pictures do the talking. I would like to hear what other member's opinion are on these. My engine had 42K on it when the dealer replaced them. It now has 43K and is still quiet (well, quieter). This engine was NOT beaten and had Mobil one 5W-40 (spec 229.5) oil changes every 6-7K. You be the judge.
If anyone wants any high res pics, PM me.

cheers
