This is a common problem for all Saturn S-Series 2000-2002. The plastic intake manifold cracks at the coolant stems, even if the engine does not overheat. This is especially true in the southern half of the US (hotter climate). The intake manifold would need to be replaced, or repaired so no further damage will occur like overheating the engine.
CarSaturn of Conyers, GA sells a repair kit to fix this problem- Worked for me. Link is below

Good Luck!
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.
Your intake manifold probably has a crack in the water jacket.
No, the head gasket is underneath the heads where they mount onto the block. Your intake manifold is bolted to the top of your heads. Some motors have coolant that circulates in the intake manifold ( I don't know what year or make your vehicle is ) so I would check my shop or repair manual. There could be a crack where the coolant flows through your intake manifold or one of the manifold gaskets may need replacing.
Assuming this is a 4.3L engine, the upper intake manifold gasket would be between the upper intake manifold and the lower intake manifold.
Depends on which one, there is an intake manifold and an exhaust manifold. The intake(normally aspirated)- you have to remove the air intake tube, throttle body, disconnect sensor, injector wires/vacuum hoses. Disconnect the fuel line to fuel rail, then you can unbolt the intake manifold. The exhaust manifold- is a little hard being against the firewall, you would have to disconnect the O2 sensor wires and exhaust pipe. I would spray the exhaust studs with penetrating lube. The upper nuts you should be able to get from the top, the bottom nuts you will need to get to from under the vehicle with a swivel and extentions.
the only thing i can think of is a crack in the intake manifold. my cavalier's manifold cracked and it was idling at like 2500RPM as opposed to the normal 1000-1500, also i had trouble with my brakes and misc other problems because of the crack. if it is just idling too high and there are no other problems i would guess that it is just compensating for the cold. if there are other little issues, i would look into having your intake manifold checked out. gotta take care of your baby because cavaliers are such great cars...... :p
The manifold itself could be cracked. I have a 2000 Pathfinder LE with 100k miles and a 3.3. I noticed an antifreeze leak on the right side of the top of the engine. Using a mirror, I found that under the manifold, there was a nice crack.
Intake manifold gaskets are leaking, intake manifold is warped.
There are a few causes: Damaged or disconnected hoses (or component) from intake manifold. Worn out intake manifold gasket. Improper replacement of a part. Cracked or damaged intake manifold.
it would be on the top of the moter
On an engine bolted to the intake manifold.
Need to know if it is the intake manifold or an exhaust manifold and what is wrong with it.
