I just got a 92 prelude SI with an H23 and after like a week of driving it the belts started coming off and a weird bumping noise started. I took it to the shop and the dude said that the bolt that holds the lower crank pulley is bent and cross threaded and that I needed a whole new engine. Anyone know if this is true? Ive been looking into getting an H22 that comes with the engine, tranny, wiring harness and ecu. Is this going to be an easy swap? Is there anyways to fix my H23?
