Allright i just bought a 1991 civic ef hatch.. i only payed 400 for it so i didnt really expect much. he said the motor blew a rod bearing and locked up. turns out its a zc motor. my question(s) are 1. how hard is it to find a rebuild kit. two the guy who sold it to me said that it had a dohc block and a sohc head. which i dont believe for a sec but i dont know everything so i'm just lookin for some guidance i guess. Is it worth rebuilding?
