Scored Main Cap Bearing - Ouch

You guys are the best. And Old Man your son is terrific. Wish his shop was in Houston area. The oil holes are chamfered, hard to see in pic. I am going to use 400 & 600 wet or dry to clean up the journal. I am doing this under the car in my shop. When i work on something I am anal about cleanliness, maybe I should have done the short block assy. I plan on checking all the mains since I have to order a set of bearings. I will also check some rods to see whats going on there. Anymore of this scoring and the engine comes out. Engine is a street engine, knurling is there on crank for seal. Thank you all for your input. I will keep you posted.
Cut the can of the oil filter, that will tell you alot.
If the filter element is loaded with trash you can almost bet all that crap went through the engine.
