[GTP Version 2.0]

Go to the dealership. there was a recall on the valve cover gaskets and it might be covered as Pontiac had to replace them. The gaskets would readily fail and the oil would hit the exhaust manifold and catch fire. A shop might charge you for a few hours labor and then the parts (maybe $300+). Its not too difficult of a job and I know there is a write up here somewhere. If not autozone.com has free repair guides.
