good luck with it all, but i had same prob in my da3 integra, cruzing at 60kms in 4or 5th gear and the belt just snapped, leaving me with bent exhuast valves............

unless the mottor is a free spinning motor (which u have discovered isnt), hence the bent valves.............its gonna be a costly fix.

good luck again.............dont let this dishearten you, get back out there...........
