Hi Linda.

You have a major problem, first, don't run the engine at all! when there is coolant in the oil, running the engine can ruin it completely. the coolant will cause bearings in the bottom of the motor to seize, if not more cause more damage.

these engines are known for blowing head gaskets and intake gaskets. in this case, if you haven't ran the motor since finding the problem, the head gaskets can be replaced and the engine should be fine. I'd recommend doing the heads even if it's only the intake leaking. that would be cheaper than having to go back in later, and there isn't much further to the head gaskets after the intake is off.
also, have a new thermostat put in while this is all being done, it's cheap insurance!

If you know someone that has done head gaskets before, they should be able to tackle this without too much problem, otherwise if you'd rather a shop do the job, just make sure to tow or haul the car to the shop.

Why wont my car wont hold water or anti-freeze and i cant figure out where its coming from or even going?

its possible that the engine is burning the coolant which would not show either by causing the oil to turn a milky color or leave a puddle were you parked. it may be just a small problem at the moment not causing the car to overheat. have the head gaskets checked for damage with a head gasket test. it could also be a possible intake gasket leak causing the coolant to be burnt but not leak into the engine oil. just somethings to check out.

Why is low coolantligt on aftading coolant ? the engine oil way passed full

Is your oil kind of milky looking??.. If I understand correctly, your oil level is much higher than it should be???. If this is so, you probably have a blown head gasket, a cracked head, or a cracked engine block.. It sounds like your coolant is leaking into your crankcase where your oil is.. If I'm on the right track, your problem is a serious one that will require some high-dollar mechanic work... Good luck... I hope I'm wrong..

Nissan Maxima 1996 Engine oil turns milky white

Sounds like you may have a blown head gasket or a cracked head. There are test that can be done to check this the easiest and cheapest method I use is drope a few dropes of oil from your engine on something hot like the exhaust if it boils there is good indication there is coolant in your oil as the flash point of coolant is a lower temperature than oil

Oil is milky

coolant/water is getting into your oil. Grand Am is really bad for leaking intake gaskets or head gaskets.

Quit driving it. You have blown a intake manifold gasket or a head gasket. 3.4 engines are known for blowing intake gaskets. Check your oil, make sure it is not exessive or milky in color. White smoke is caused from water/coolant entering the cylinder.

Oil light came on then we added some oil and then that night while driving the battery light and oil light came on and the car stalled at a stop sign. the car has been sitting now for a week and it looks...

The oil warning light doe not mean 'Add oil,' it means there is essentially no oil pressure, a deadly condition if it isn't caused by a failed oil pressure sensor.
That warning light should never have to come on during operation if the oil level is checked now and then.
If there is visible oil in the coolant, you have a seriously blown head gasket. Check your oil dipstick; it may have a milky substance on it caused the mixing of coolant with the oil.

I have a 2001 grand am v6 that I have to add coolant every few days. The engine is running a normal temp, and the cooling fans are working.

There are only 3 possibilities:
1) Coolant is leaking on the ground - puddle under the car.
2) Coolant is leaking into the engine crankcase - engine oil is "milky" looking.
3) Coolant is burned during combustion process - defective head gasket or intake gasket.
Let me know what you find and we will go from there.
