I'd put my money on it being the headgasket since you have that engine, I've done 2 or 3 on mine. Blew up my old motor because I tried to get it home with a blown head gasket, so I've been through a lot of them. It's not so bad once you've done a few of them, only takes me about 4 hours to do mine now. The front one that is. I had to do the one against the firewall on a Cavalier not too long ago, wow, that was a lot of work, that engine compartement was horribly designed. To get the fan out you have to dis-assemble the air-cleaner, and take out the battery and sneak it through where the battery sits. Just an example of how well designed they were
