OK I'm pretty sure its a blown head casket but before I pull my heads off. The car has 151K miles on it and it recently started doing this.

Changed the thermostat the water pump is fine, I ran the car with the thermostat housing off water came running out. The radiator is not blocked i can see the water coming threw the cores.

Here is where it gets confusing, The cooling system seems to start to get a lot of "air" in it when i start driving, especially when i put my foot in it. The water doesn't come out the tail pipe there's no puddle on the floor except from the overflow tank.

I pinch the upper radiator hose and crack open the radiator cap and a lot "air' is released. When the engine runs there's exhaust or air coming from around the rocker stems (the ones that carry the oil to them) it is consistent with the turning of the motor.

The way I concluded that I am losing all my water is that the "air" pushes it all out I've seen it bubbling in my overflow tank and it gets so pressurize that it starts coming out of the cap itself.

Oh and it looks like Ive lost some oil, my oil is not milky. I think its getting mixed up with the "air" exhaust around the stems and going into my upper intake.
Sorry for the long post.

What do you all think?

yup. sounds like a headgasket to me.

WTF are you trying to say Bro your not making any sense at all. Water shouldn't be coming from the engine through the exhaust. That is condensation build up in the mufflers . If there is white smoke coming out the exhaust then you would have a blown head gasket

If the heads are warped enough or a bad blown head casket water would spill into the pistons and out the exhaust. Had it happen to me on a old cougar I stick the water hose in the radiator and out the exhaust it came out funny looking really.

Yeah dude. I can honestly say I've never seen anything like that before, and I've seen some pretty efed up engines before.

Yeah lets just say I was suprise it still ran but not good at all. Yeah well since it looks like its going to be my gaskets might as well do a valve job on it. Take a look at my piston walls see how all the goes.

That many miles, best to freshen up rest of engine.

water is a byproduct of efficient combustion...if your tuned right you will drip water from the tails

compression test would tell you for sure and it would take all of 15 min

also not to sound like a wetard but if your radiator cap was bad and not sealing down properly once you start building pressure it would blow out through the overflow tank too.

ure cooling system usually runs @ 13-16 psi normally.... oreillys or autozone rent a tool to check your cooling system pressure.... its kinda like a keg pump with a gauge

Ive replaced the radiator cap already, too much pressure and air build up in the radiator and there's other signs of head gasket problems like the air puffing out the rocker stems. The car runs great for about 10-20 minutes or if i keep burping the system.
