Q: How much does it cost to repaire it? The engine is a b18cl.

A: ok from what i get your saying...is you basically spun the bearing. shouldnt cost you that much at all to fix. unless you messed up the crank and/or the rod. now if your saying that the bottom of the rod broke where it holds on to the crank.....well your better off looking for a new motor. depending. you would have to tear the motor completely down....and check over everything. its what i would do
