when the car is cold take your hands and run them over every part of the cooling seystem you can touch, if it comes out dry you may have a bigger problem.

start your car, let it run until hot (go get a slurpie or somthing) and then while car is still running put your hand right up to the exhuast. hold it there for a few seconds, if your hand is moist, damn, you have a broken waterjacket or head gasket, big trouble. pray that you just have a split hose.

i bealeave the water jackets are the lines in your block that water travles through, if one is busted, water will leak into your cylenders and be burned with fuel causing moisture in your exhaust...

allright.... did the runing my hands over the rad. lines, it squished and squashed its way thru, i could see it running in and out of the resivor, didnt get that much back but i poped the radiator open, and the fluid was almost to the brim inside the radiatior... maybe theres a clog in the return lines somewhere? i really dont think its somthing as serius as what im afraid of.... cuz the oil is clean, and no power loss or strange sounds, thanks alot guys... need to get this fixed b4 i can throw in that nice little shift kit ya know?!!!!!!

there is a pot metal fitting on the bottom of the manifold, under the TB.
If you look at the passanger side of the engine, you will see a 5/8" black formed tube that bolts to the engine, and runs back under the TB.
between the black tube and the manifold is the fitting. it will most likely break as soon as you touch it, it's like 8 bucks at the dealer The dealers around here knew exactly what I was looking for whenI went in, but that might not be so near you. Ask to look at the screen and point out the fitting to them.
Be prepared with a tap and dir set the size of the fitting, you will more then likely need it.

I would say to look at your engine when it's HOT. When the car's cool, the cooling system isn't under pressure. It's when the coolant's hot that the whole system is pressurized. A tiny pinhole in a hose that doesn't leak when the car's sitting might turn into a little geyser when the car's hot.

I had a leak like that once; in one of my heater hoses. I was losing coolant but didn't know why. Popped my hood one day after driving, and saw steam- my exhaust manifold burnt a pinhole into my heater hose. Coolant was spraying in a thin line onto the exhaust manifold and evaporating. It didn't do that when the car was cold.

The brownish-bit of the antifreeze is probably just old rusty antifreeze, that's all. Combine that with crusty white deposits from using regular water for the 50/50 mix (and not distilled water, meant for steam irons), and you can get a funky looking overflow bottle.
