And how did you delete the stat. Did you cut the guts of the old one out and leave it so the seal is still there I hope??

You need to put your stat back in. You said it was always around 210 eh? Well water boils at 212 at sea level. It's not letting it cool in the radiator and boiling off.

Ive had no stat for about 20,000 miles now and no coolant loss. My efans kick on around 210 though so the car never sees higher than that. I would not relate the tstat to coolant loss. Its also possible that you have a slightly cracked head...porting and headwork definetly could cause this and if you, it could be slowly entering and combusting with air and fuel. If its mild enough, you really wouldn't smell it. I would pull your plugs to see if they have fouled and if they look bad, you may have that problem.

But why would the reservoir overflow with both its and the radiators?

If you have air in the system this could happen very easily. Im not really sure on bleeding air w/o the thermostat. What we do at work is just when the car is stone cold and w/ a t stat, leave the radiator cap off. Crank the car. As it warms up some of the water will begin to boil out and over due to no pressure and the cap being off. It will stop boiling over when the stat finally opens. The boiling aids in the bleeding. First things first tho, pressurize the system and do your leakdown test to determine if you are leaking, or there is air there.

And hence why radiators use a pressure cap, thus increasing the boiling point. Same concept as a pressure cooker.
