no you need to replace the lower intake gaskets . P.S. should have the rear head checked for leaks also they are known to leak also
No additive is going to help - you need to get your head gasket replaced.
You either have a blown intake gasket or a blown head gasket.
the answer is yes
Sounds like either a blown head gasket or blown intake gasket without knowing more specifics.

a blown head gasket needs to be replaced as early as possable. it will only get worse and additives like water glass, etc will gradually worsen the problem.
gasket connecting 2 or more solid materials to form a vacuum and pressure seal. the term "blown" indicates a failure in either or both the vacuum (air intake)or pressure (coolant passages)
Blown intake manifold gasket or blown head gasket, figure on $600 to $650 to get intake gasket fixed and if a head gasket your looking at least $1,000.
The 3.8 GM V6 is prone to blown intake gaskets much more than blown head gaskets. The blown intake gasket causes a loss of coolant which in turn causes overheating and a blown head gasket. The problem exists with most 2000 to 2003 vehicles equipped with the 3.8 Liter V6. There were defects in the upper intake manifold gasket, throttle body nuts, and the throttle body gasket.
most likely a blown head gasket, cracked head, or bad intake gasket. with the s series. i would venture to say blown head gasket.
Not unless you have a water cooled intake manifold, which is very rare on a car.
Yes, change both of them.
