The intake manifold gasket may develop and external engine oil or coolant leak. In some cases, an internal coolant leak may occur causing coolant to mix with the engine oil. Our technicians tell us that operating the engine with a coolant/oil mix can result in internal engine damage. Replacing the intake manifold gasket should correct these leaks.

Pontiac Montana Reviews
Purchased a 2003 Montana with about 20,000 miles on it. The thing with the Montana is that a lot of annoying little things go wrong. The fuel gauge does not work, warning lights go off when there are no actual problems, lower plastic side panel gets knocked off in a car wash, doors have to be unlocked/locked and unlocked again to open ... it does not inspire confidence. I am very fortunate that my mechanic is a good friend and never tries to squeeze money from me for these 'non-issues'.
To be fair, the Montana has gotten me and my family from point A to B. Like another person mentioned, this vehicle has its warts (maybe with a hair growing out of it) and you'd rather not take her to your high school prom - still, the engine, drive-train, braking system have never let me down.
Regular maintenance is the key.
I have a 2005 Montana. It has been a very reliable car. I have put quite a few brake pads on the car seems to go thru them and then they squeal. I replace about every 30000 miles. My main issue with it now is that from a cold overnight start I get bad gas fumes once car warms up there are no more fumes. Still trying to locate what is causing it. Took it to the shop and they say I have no leaks. They have had me put in fuel injector cleaner says they should help I am on second bottle and still has the smell.

Every time I have my oil changed (3000 miles) the engine light comes on after approx. 100 miles. I keep taking it back and they do something under the dash to turn it off. I am getting tired of taking it back and would like to know how to do it myself.
