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.

the gaskets were replaced but they let the gasket sealer dry then came back the next day and put more sealer on it. which didn't work the car was driven about 10 mins. the next day checked flulids and notice the oil was milky does this mean the engine is gone. or is there anything that can be done?
