[QUOTE=KPowerEP3]I'm going to give you the best advice in this thread. If you're really so dense that you don't comprehend "locked up" and then...get this...you try to turn the engine by hand and it wont turn. Now what would that lead one to believe? That maybe, perhaps, possibly "locked up" means one of the following; seized, blown, "exploded", trash, garbage, giant paper weight, etc. Honestly, if you can't figure that out, go get yourself a nice civic dx, leave it totally stock, and drive it until you can afford something else that you don't need to touch.
**** you this is just my first 300zx i am fixing i am not that stupid maybe the timing is just off and i am not gonna go and buy a new engine.
