Report: Intake Manifold Gaskets May Leak Coolant or Engine Oil
Chevrolet Malibu Problem
Model Years Affected: 1997, 1998, 1999, 2000, 2001, 2002, 2003
Engines Affected: 2.4L 4 Cylinder, 3.1L V6
Average Mileage: 90,906 mi (22,000 mi - 178,836 mi)
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.

Coolant began leaking around 70K miles. Added stop leak to engine, which has been sufficient with little leaking since (mileage now at 90K).

I'm on my 3rd replacement of this same part! I am told each time that it is a known problem and they have totally redesigned the part to rectify the problem...each time costing me over $650.

Intake manifold gasket needed to be replaced. Went to get oil changed and tech advised there was oil in anti freeze. Seems to be a common problem.

Intake manifold leaked coolant for the second time. The first time was at about 60000 miles and was serviced by the dealer.

The repair cost me about $2000.00 at the local dealership. I had them change the water pump also since they had the engine dismantled. Now the car has a kicking problem when I stop for a light or driving very slow. Seems like the trans.

Mechanic said intake manifold gasket leak and cracked manifold-$1500 10,000 miles later, leaking in the same place, behind power steering pump. I took pump loose and laid to the side-antifreeze leaking around two manifold bolts. These bolts come new with a coating on the threads to seal and keep them tight I guess, its not enough. I took out the two leaking bolts, cleaned them up on a wire wheel, coated them very well with sensor safe Hi-Temperature Silicone, put some in manifold holes also and tightened up, put rest back together and let sit 4 hours for silicone to dry and now have 150,000 miles on car with no leaks. An old mechanic told me 30 years ago to silicone your intake manifolds for trouble free future, no matter who luaghes at you for doing it. I think it could be the bolts causing the problem, not sure. It couldn't hurt to use gasket sealer when replacing, but of course your mechanic would lose business that way. Car won't start half the time-theft system or what? When it runs I love it-LOL
