Yes it can but the intake is probably the bad guy. General Motors had alot of problems with them.
intake manifold gasket if it is coolant in the oil
Not unless you have a water cooled intake manifold, which is very rare on a car.
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.
Most likely the intake manifold gasket is leaking.
There is coolant on the ground occasionally. How will I know when the intake manifold gasket is leaking
Intake manifold gasket
If the leak is bad enough i believe it can but i would check your valve cover gasket first.
You shouldn't need to take off the intake manifold at all so, to answer your question, no. However, if it the exhaust manifold you mean, the answer is still no. It should be a multi-layered metal gasket and the only reason to replace any gasket is because it is damaged.
Answer Yeas absolutuley can, Typical of the 3.8 and the 3.1 motors, Have also seen it it in the 3.4 motors. What do you have? It is probably an intake manifold gasket problem, depending on the motor.
intake manifold gasket,head gasket,cracked head,cracked block. was it overheated? was cold water added to hot engine?
Is it water ( condensation ) or is it antifreeze. If it is antifreeze it should be smoking WHITE out of the exhaust pipe and if it is then you have either a blown head gasket or a leaking Intake manifold gasket.
White smoke exhaust usually means either a head gasket leak or an intake gasket leak. Both are cheaper to repair sooner than later.
