Intake manifold leak
#18
Keep in mind, I BELIEVE I remember that GM "fixes" the problem when you have it fixed at a dealer (maybe other shops do too, but IDK)...If I remember correctly, the dealer not only replaces the gasket, but they change the bolt pattern to prevent it from happening again. You might want to ask a dealer if they do anything to prevent it from happening again. It may just be that they use a different type of gasket...but for some reason I want to say the guy told me that they came up with a new bolt pattern to fix the problem because they were leaking around a bolt or something like that...I am pretty sure though that there is SOMETHING they will do different than just replacing it to 100% the way it was from the factory. So check with the dealer or shop you have doing the job and see about that!

LIM Gasket
My "Low Coolant Level" light suddenly came on (Friday). When I checked the overflow tank the level was low so I added coolant. In doing so I found the LIM gasket showed signs of leaking. Talked to local mechanic today who quoted me around $525.00 to fix it.
