I know our precious S65's can be a bit fragile, but you guys are overdoing it. Idling beyond cold start is not really doing any help and is actually just wasteful. You need to actually get the car moving to get fluids going and warmed up. Of course, still keep the rev's low, but these aren't classic cars with carburetors and whatnot.

If you live in the snow states, than I can't really speak on that.

I'll try and find them.
Those are really bad... I would not use oem or Wpc.
Not really. My Originals with only 40,000 looked way worse. These look like a better even wear. The OG's had bad wear on some.

No really they look bad. This forum has a perspective issue that comes from owners of expensive German cars that have no experience with hands on work. Bearings are not wear items and should not show that amount of it. The entire idea of a bearing is that it is a highly measured part that creates a very specific clearance between metal parts so they never contact each other. That amount of bearing wear demonstrates otherwise.

I've been told this. However the 3 motors I've opened showed wear. (1) Ford, (1) Toyota and my M3. The M3 did look worse than the others but the S65 revs 3k higher than the other two V8's. Another motor known to eat RB's is the 5.2L current Mustang which only hits 7.3k limit. It's a cross plane crank so that makes more sense. I understand these motors are not apples to apples comparisons to each other but the two higher revving motors have RB problems. So to expect no wear is pissing in the wind but that is only my opinion based on my very small limited experience. I am not a motor builder or mechanic. I'm just an electrical engineer who likes cars and tinkering.

what Uber said..you don't need to let idle before driving. the manual states you simply drive after starting and avoid high rpms until temp. otherwise it's a waste of gas and you risk inhaling all that pollution

Opened and assumingly put together three engines sounds like a fair bit of experience and more than most of the rest of us...

I'm sure other folks know better than me. Refreshing parts on or in a motor isn't really that big of a deal. Besides I don't care who is right or wrong but I've never seen perfect con rod bearings in my experience but a few motors of experience isn't much.
