Yes I am back with another question about my 78 buivk regal 3.8L V-6. Now I noticed sunday my overflow tank was empty first time in over 2 or 3 months all I had at the time was water filed it up to the full line and forgot about it drove 2 days about 65 miles all together no th things empty again. NO smoke anywere no steam not even a drip on the ground, I let it run in my drive way for about 12 min. not a thing leaking.
Now when I start my car in the morning to let it warm up I noticed about a tea spoon of black sute comming from the tail pipe but after the high idle slows down nothing out of the pipe.
Any idea were my water is going?

WHEN YOU DRIVE ARE YOU SEEING A WHITISH COLORED EXHAUST FROM YOUR TAILPIPE? THAT IS STEAM. IF YOU ARE USING PURE WATER FOR YOUR FLUID, THEN IT WILL DISAPPEAR THROUGH EVAPORATION. QUITE NORMAL. RE-SERVICE THE RADIATOR WITH A HALF AND HALF MIXTURE OF WATER AND ANTI-FREEZE AND YOUR PROBLEM WILL DISAPPEAR

It's possible that your system wasn't full in the first place. If there is no head gasket problem (no white smoke) and no drips to speak of, then either a small leak is hitting something hot and evaporating, and not big enough to drip while cool and not under as much pressure OR the system wasn't full to begin with.
I would suggest while the system is cool you take off the radiator cap and start your engine and let any air in the system bubble it's way out, you should see the level go down a bit, you can top up then and replace the cap. Then refill the reservoir and see what happens.

If you were burning water it would not be black but rather the light steam color. You could have a leaking head gasket that allowed it to disappear this way, it would probably get worse and maybe water appear in your oil. My best guess is a very small leak somewhere a hot engine can evapotate such and it not show up.

If it's losing fluid, & it's not leaking on the ground, it has an internal leak in the engine, maybe a head gasket. It may be slowly leaking into the combustion chamber & burning it off.

Water could be going into the engine, you could have a blown head gasket, or you could be losing water through pinholes anywhere in the cooling system (it would come out a vapor and you wouldn't see it).

Both previous answers are correct. I'd keep an eye on the oil dipstick. Is it overfull? Milky in appearance? Good Luck!! :-)=
