My Cat rod bearings...

[Brock]

I was wondering this as well, probably hard to see from the pic but there are some scratches that run sideways across the bearings. Only way I could see that happening is if there was contamination.

I can chalk most up to coolant or bad mechanic but number 1 cap uneven wear and number 5 rod wear have me wondering..

All I can do is measure everything when I put it back together real good and plastiguage it and hope that the crank isn't warped at all...
