Usually when you leak oil that's an indication that the intake manifold gaskets need to be replaced or your intake manifold is shot.
Yes
By replacing the whole gasket.
A manifold leak is usually in reference to a failure of the intake manifold gasket. It can leak air, oil or coolant. It can leak to the outside of the engine or internally into the engine. A manifold leak may also refer to the Exhaust manifold that is leaking exhaust fumes from a bad gasket or a crack in the manifold.
A bad intake manifold or manifold gasket can cause water to leak into the oil. Some newer cars have plastic manifolds and they will crack from age.
Because it 's leaking- OIL, ANTIFREEZE, or vacume leak
Check to see if there is coolant on the engine block. It is common for the Monte Carlos, along with other GM cars equipped with the 3400 V6 engine to experience leaking intake manifold gaskets. A leaking intake manifold will cause oil to leak into the coolant system and even worse, for coolant to leak into the oil system.
$150-200 u need upper and lower intake gaskets new o-rings for injectors radiator fluid and you should change the oil
I wouldn't recommend it. Replace the gasket.
it could be your rear main crankshaft seal, the back of your intake manifold, then back of your intake manifold.
If is oil then you have a bad intake manifold gasket. If it is transmission fluid then the cooling tank in the radiator is bad.
The intake manifold or the timing cover seal.
