I overheated my 82 and the thermostat gasket got toasted, and started leaking. I replaced both the thermostat and gasket, but when I tried to bolt the upper radiator hose back to the block, it seems that the bolts just go right through the holes where they are supposed to screw into the block. I dont think theyre stripped, because they came out fine and I never had a chance to screw them back in, they just push all the way in. Is there supposed to be a nut on the other side?? I didnt see any when I took it off... Also, where it bolts on, where the holes are, is that actually part of the block itself, or is it something that comes off and can be replaced (if it is indeed stripped)? Also, in a somewhat unrelated problem, I broke off a small plastic piece when replacing some vacuum hose. It runs into my EFI from the side of the engine. The part I broke is where it comes FROM the side of the engine. Three vacuum lines come off of it, and two go the the EFI. The engine seemed to run ok, once I plugged the vacuum leak on the EFI side, but I dont know what that does, or if I have a vacuum leak on the lower part. Sorry for the long post.
