yeah, i had a 2000 pontiac grand am with the 3.4 v6, and they redesigned the lower intake manifold gasket at least 3 times i think. mine was replaced twice in the period of a year for leaking, but i was luck, i only had a coolant leak. others that werent so lucky had oil leak into the cooling system, cause some delicious sludge, or coolant leaking in the the oil, which ate away at the bearings, from what i understand....
i will say though, that i had the car for 6 years, and replacing the gasket (second time under warranty since it was within a year) and the water pump were the only problems i had with it, so maybe i was lucky, but the car treated me well for being almost 10 years old
