Find me a good photo hosting sight and I’ll toss up bearing pics…they had some copper showing…

Also after my tune cruise control will not activate. Heard of that before? Going back to tuner Thursday.
Your mechanic told you to observe a 600 mile break in period?
Rod and main bearings don't require breaking in, only piston rings do.
44,000k is a pretty short life span, are you doing a lot of track work?
