I noticed that my coolant is low, and i did a check and sure enough theres a little bit of white smoke coming out of the exhaust, so i figure that the upper intake is gone. Fortunitly i can drive my 94 GTP until i take the bonne to be fixed later this week but i was curious how much this repair runs? I dont have to the time or knowledge to fix it myself so i need to take it to a dealer unfortunitly.

By the way, i'd like to thank all who posted the info about this problem because otherwise i might not have realized how serious this could be.

Mine was 600 some odd dollars, but was covered under warranty. It should be around that, give or take a couple hundred dollars.
Last time I was at the ACDelco distributer here in town, the owner said there was a shortage of upper intakes. He had just sent his last one out the day before.

Good thing i didn't get that 97 se with 123k miles on it eh..

He also said changing the radiator cap helps prevent the failure from happening, helps keep a good seal. Is there any truth in this? Sounded like but who knows.

Rad cap!?!?!! Ok... it'* known to be heat related, not pressure related.
