If the bearings are not damaged ,they do not need to be exchanged, just keep them in order.

JT: As I recall from member spock605 and his euro om 605 he talked to meyle and they said to not glaze break or bottle hone the cylinders.

BLACKESTATE: I have swapped motors several times, as I had a "good" replacement engine that was garbage. It had a bad piston/bore. In my opinion, and as I have learned from working on these cars don't fix something that isn't broken, it usually takes a lot of time, patience and $. As long as you're comfortable with how it sounds, responds, and feels, regardless of the blowby, I would set it w/o pulling anything. I would however, pull the oil pan sump off and see what kind of guk is in the oil pickup tube screen, just because it takes 10 minutes to get it off, plus you'll be able to see # 1 and # 2 cylinders, check for any scoring or scratching. If all looks well, you have an engine that is ready to go another 250K. When installing I would recommend checking the IP timing, replacing the timing chain, and adjusting the valves while you're in the mindset to work on your old MB. Hope this helps! Keep us posted on how everything is going. Also be sure to checkout the rental tool program this forum has, you'll need a couple 'special-ish' tools to make removal a little smoother... Again, GOOD LUCK
