![]() Vacuum air leaks into the manifold due to a defective gasket that will upset the air-fuel ratio. Poor engine operation, lean operation, rough idle.If the manifold gasket has failed, oil can leak from the block to the exterior of the engine. ![]() On some 6 and 8 cylinder engines, the intake manifold sits atop an oil-lubricated area of the engine block. However, there are other causes of engine overheating, so a mechanic would have to determine the actual cause. If the leak at the manifold is a leak of engine coolant, it can lead to engine overheating. If the manifold seal to the engine fails, coolant can leak externally or even into the engine oil crankcase, where coolant can be noticed in the engine oil. In some applications, the manifold has cooling passages within.
