Looks like I will be taking them into the shop that assembled the rotating assembly. I want to see what he has to say about them. That coating cost me $250.

Oh, is that the WPC stuff?
Similar, Micro blue. Link in the first post. And it was just under 200 according to the receipt.
The front one is installed between the front valve cover and the lower intake manifold and the rear one is installed between the rear valve cover and the pre-turbo intake splitter. My main problem was that the stock PCV valve has been replaced with a straight through barb so without the rear installed I had a major vacuum leak that was being sucked into the lower manifold from the valve cover. With the rear installed it sealed that leak so the crankcase is now under vacuum at idle. I could have possibly put a working stock PCV valve back in.
Oh id definitely like to see more on this...subscribed x2
Id say yours look like #16, not 12
I haven't seen a lot of super low mile bearings because I have never tore down an engine that new, but I don't like how it looks like the crank has contacted the bearing surfaces. I especially don't like:

because the crankshaft is not contacting the bearing evenly.
IIRC my rod bearings in my 95,000 mile motor did not show that type of polishing and in generally looked better than yours when I changed them (before it blew up later)
I also don't like the weird appearance of the bolt holes on the upper right part of the girdle there. Are they dirty?
it looks like #16 to meQuote:

One of the causes on #16 is insufficient prime of the oil system. Did you see pressure build on the gauge before you started it?
The stuff in around the bolt holes looks to be a grey anti-seize, or something. All the threads were covered with it when removed. I will get pics tonight.Quote:

woops...I meant 16..
