yesterday i just recieved 2 d16z6 motors, with 115,000 miles..only the problem is, they both have bent crankshafts. I've already pulled out one crank. If they both have bent cranks and 115,000 mi. would they be very reliable motors? what would cause them to bend? i currently have a d16z6 in my civic and it has over 200,000 mi. and its still running pretty decent. the motors were free, so i decided i might as well rebuild one then swap it in.
