well i think that the bearing spun because of a lack of oil changes, and the car had been abused before i got to it and when i had it (practicing drifting) so i guess it will be a waste of time and money to rebuild this motor? i thought that it might be that one/or more of the bearings are messed up this means that the crank and block need to be measured to make sure that the clearneces are ok? i just figured that i would see the bad bearing(or bearings) when i took it apart and replace them all. it is making a slight knocking noise it isnt that bad, but a knocking noise non the less. i guess i see where you guys are comeing from with this, if i have to rebuild all this and then take it to a machine shop and replain the head, and buy all the parts, measure the block and crank, i will be at the cost of an SR, or just be cheaper to buy another motor... i thought that this would be easier but i guess there is more to it than what i thought
