I just bought an 88 7M-GTE for $1000.....the guy thrashed it before I bought it and (he says) it spun a rod bearing. We went to a Toyota service shop and they said it is common for the head gasket to go out. But when I bought it the guy I bought it from put his truck battery in it and we cranked it over, but it was out of fuel. While it was turning over I did hear a small knocking in the engine. So my dad and I were looking at the car yesterday, and I guess I wasn't thinking about it, but it doesn't have an intercooler!! I know he probably drove it with out it, but what will that do to the engine? I havn't started the car yet because it needs a new battery, but I'm trying to find out what it needs before I figure out what the engine needs!!? Any ideas on what happened/will happen to the engine?
