Just started reassembly of my engine and when I opened up my main bearings and the 1st "oh, $#1t" moment right off the bat. Now I'm gonna try and post a couple of pix, something that had always given me fits, here goes/ These are brand new, tri metal but probably from the 80s or maybe earlier.
I did set the crank in and plastigaged the clearances,(which are great) and then stopped to ask. I've built engines before, but have never seen anything like this. I can't catch a fingernail on the gray coating where it goes black. So what do you think, junk or not? The other 3 mains in the same box did not look like these, they look normal.
I got the rod bearings same brand but from a different seller on ebay, also unopened and new but from back in the day please nevermind the background, they're setting on a stool that has been around the block a time or 3.
