So I'm going through my 135k mile original engine and I was was thinking I was wasting my money by replacing the rod and main bearings when I found this.
The number 3 main is junk. It looks like it melted. All the rest of the bearings look great.
The crank looks like it has some galling on it, hopefully it can be polished out.
I can't imagine what caused this. I'd it was oil starvation, I would expect to see more damage. If it was a clearance issue, it would have shown up sooner. I've put 15 on the car since I've owned it.
Maybe a plugged passage in the block??
