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.

I have had to replace my intake manifold gasket three times now, three years now. This car has been nothing but trouble since I got it.
car was leaking coolant, had to have intake gasket replaced. Leaked coolant again, had to have freezeplug replaced. continued to leak, was told the head gasket was blown. been driving it for about 2 years on blown head gasket.
