So had the rod bearing changed last week, I ended going with WPC coated with APR bolts. But some interesting results with the old bearings, as you can see from the photo one bearing is totally shot. I'll post the Blackstone lab results once I get them back. Now what's puzzling me is casting numbers;
6 stamped 605
4 stamped 606
2 stamped 602
I would have thought that you'd have 2 casting number sets. The 602 is really worn down, any ideas what these numbers mean and why there would be a mismatched set?
Coupe had 109500km and the really bad bearing was on cylinder #2.
