Message	I recently took apart a motor with a spun bearing and I found this [ http://s8.postimg.org/qzflx1ax1/image.jpg ] I am thinking that's not supposed to be like that lol. Question is what made that happen? Bad oil pump? I looked at the heads and took off the cam shaft and heads looked fine so I didn't think of the oil pump as being bad but when I saw this I was confused. Second part of this what are my options on the block? Does it have to be oversized and bored at a machine shop or can I just replace the Bearing and call it a day?Are the Pistons no good after the bearing spun? Is there a way of measuring the block to see if I can save it without oversizing it? Thanks
