i have the same motor in my ae82 and it not relly that hard to put a motor in youself.
is there any chance i would be able to come have a look at your motor because i just done the head gasket in my motor and i think i have put some vacumes on wrong and i have been looking on the net for a week now and i can not find a vac diagram anywhere for the same motor.
