Alright so I guess what I'll end up doing is.. solve the oil leak, flush the coolant system properly, as the previous owner didnt seem up to it, thing just runs far too hot for my liking. And then I'll try tracing all the vaccum lines and then inspect them all, because there's an evident vaccum leak somewhere... umm also, can anyone tell me what optimum running temp would be for one of these cars? Just need it as reference for when I flush the system.
