Intake Manifold....smelling radiator fluid fumes in cabin or white smoke in exhaust.
Exhaust manifold or cylinder head....smelling burnt oil in cabin or black smoke in exhaust
bad oil rings==head gasket== valve seals
a bad head gasket or intake manifold gasket.
A blown head gasket could cause an engine to overheat, just like a bad thermostat in an Impala. One difference is the head gasket will probable leak coolant, either in the cylinders or in the oil.
If it is leaking from a bad head gasket, it is because of a bad head gasket. If it is leaking from a bad intake manifold gasket, it is because of a bad intake manifold gasket.
How do you know the gasket is not bad? f you oil is milky then there is moisture mixed with the oil. This can be a blown head gasket or a warped or cracked head.
You may not see anything on the gasket. Usually a head gasket "blows" because of overheating that causes the head to warp. A gasket can be bad but there should be a visable break very often in the ring around the cylinder.
check for blown head gasket do a compression test
A head gasket is only one of the many gaskets in the engine. Each has a separate function and failure by any one gasket will result in different type of leakage. A head gasket failure is perhaps the most disruptive.
Yes , engine coolant can get in an engine cylinder from a bad head gasket , a warped or cracked cylinder head , a bad intake manifold gasket etc. ( P.S. I'm not a mechanic / technician )
replace it
A bad head gasket or a cracked head will do that.
