why did it overheat the first time? address that problem first. Fix it then throw a head gasket on it. if the plastic timing covers are melted then goddamn she cooked that motor! my sis did the same thing to her single cam because the cooling fan fuse blew and she roasted it. i replaced the fuse replaced the head gasket and when i went to torque the head back down all the head bolt threads were strippin.. i guess it got cooked so bad it soften the metal or something. ended up getting another block. overheating issues is the worst for hondas because of the aluminum casting. if im wrong plz guys shed some light
