So my car is blown to hell (BHG FTL). I'm a broke ass and don't have the money to fix the car right now. I've got an opportunity to buy a 91 240sx fastback for $150: Front end is wrecked, guy has all the front end parts already primered. On to the bad, the motor smokes after about 5 minutes of startup...no clue what's wrong with it yet, I gotta go take a look at it. Any ideas as to what's wrong with it yet?
