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.

intake manifold leak
Coolant leak at intake manifold gasket. Quoted $750 to fix.
Noticed that I was losing coolant. First thought the heater core was leaking, replaced that and still had the leak. Then realized it was the intake manifold gasket on the drivers side, after allowing it to leak for awhile I broke down and fixed it. Shop said it would be $1,200-$1,500 to fix. I did it myself, parts total about $100 and it took a total of about 13 hours. VERY involved job but it can be done. No more leaks.
I've had the intake manifold gasket leak twice in the life of the car. I have the car in for a tune up and the mechanic is suggesting I have it changed.
i had both lower intake gaskets replaced and 6 months later i noticed a slight oil leak on both driver side and passenger side of the engine around the manifold edges. no internal coolant leak and oil is still clean with no coolant to oil mixture
same prob. as above. i will replace
bout 800 bucks to fix
