When the exhaust pipe is cold, water vapor will condense as the exhaust cools on the pipe. After the pipe heats up, the vapor will not condense.

Remember that the combustion of hydrocarbon fuel produces both carbon dioxide AND water vapor as a normal part of the process. All gasoline engines produce water vapor and all water vapor condenses if the exhaust pipe is cool.

But if you are still having lot of water come out when engine is warm then it could be something to do with where you live. Is it humid where you live?

Im not that far from you for my General area Im by 401/Trafalgar :)

thats the thing even if I drive it for a few hours it still spits water

If you were in fact leaking coolant through the head gasket in the amount you're described you would notice it drop fairly quickly.

Not only that, most head gasket leaks don't act like that anyways.

Most commonly;

- A leak between the coolant passages and the oil passages result in water in your oil making your oil resemble a chocolate milkshake and not as much oil in your coolant (some but not a lot. This is because once the engine heats up the steam forces its way into the oil. not the other way around.  Water pressure>oil pressure

- A leak from your coolant to your combustion chamber usually will force combustion gasses into your coolant system making it either overheat or overpressure. Combustion gas pressure> water pressure.

from the day I bought it till I found the Thermostat housing leaking its never had an issue with loosing coolant even from the day we picked it up till now the coolant is ALWAYS between hot and cold ( if i let it sit overnight in the morning the res is slightly above the top mark

as for the day it DID Heatup (I technically cannot refer to it as OVERHEAT because the car was stopped just as it nearly hit the upper normal mark on the gauge) the coolant overflow was full but not to the point that it was at the filler neck

as for the oil its clear when i check it (note: a little dirty from neglecting an oilchange ) but not cloudy whatsoever

as for the pressure every so often I pop the hood and check the fluids/check the hoses etc.. as im not the only one driving the car I don't want whos driving it to be stranded so the day it did creep up as mentioned it pulled over immediately popped the hood and checked the hoses to my surprise both upper and lower pipes were not that hot, I could hold my hand around it for any amount of time without burning my hand.. I set my hand on the rocker cover it was warm, the heads were alot hotter but nothing that showed it actually WAS overheating.. the engine was running flawless, no ticks(aside to the all so known injector ticks)/knocks and drove beautifully

when the car was stopped the needle was hovering about here
(this is not the exact cluster, this cluster is my new KM to Miles one for my project car
