hullo, i'm looking at buying a 92 pontiac sunbird but it seems to have a problem.... it runs great, it's not leaking oil or making any noises but it is leaking white smoke out the exhaust. the guy who's selling says he thinks it's leaking antifreeze or something out the fumes and that it might be a cracked head gasket. mind you, i know nothing about cars but when my aunt's head gasket died on her car it reeked of oil and made terrible noises. if anyone could give me an idea of what might be wrong and how fixble it is i'd worship them like god for at least five minutes... Thanks!!!

Hi all, I'm getting moving on an engine swap. A 2.2 from an '87 Charger is going to replace a 2.2 in an '87 Caravan. I have the engine from the charger out and now I'm getting started with the Caravan. Both engines are carbureted, by the way. I just found out that the Caravan does not have an O2 sensor, nor a feedback carb. The 2.2 from the charger does have both. How can I make this swap work right? Do I have to swap spark control computers to accommodate the O2 sensor readings or does the feedback carb connect directly to the O2 sensor? I can always just put the non-feedback carb on the good engine and just be done with it, but the Caravan has been sitting for about 4 years with no air cleaner attached. I'm fairly certain it would need at least a very good cleaning and lubing before I'd want to use it. So... what do you all think? Swap computers or not? Swap carbs or not? Thanks a million!
