2003 Pontiac Montana Question: intake gaskets
Answer #1Oakman December 24, 2009, 15:14Master
Replacing the upper and lower intake manifold gaskets on a 2003 Pontiac Montana van is a 6+ hour job for a professional technician. It is a very complicated job which would take way to long to explain here. If you are intent on doing this your self I would suggest you purchase a repair manual and review the procedure before making your final decision.
