Default Coolant leak

Help!....My 2002 PT with 76,000 mi. started over heating and I flushed the cooling system with Pennzoil heavy duty radiator flush and it worked fantastically, (there was lots of rust in the system). I replaced the thermostat and seal and also the radiator cap....but I still have a leak some where. I am getting coolant "spraying" on the front pass side of the head (it builds up in the area where the head bolt is), It's not a crack in the filler neck that I can see, I know the water pump is working well because the heat works and is very hot no smell of coolant in the car so it's not a heater core, no leaks on the ground, no leaks in the hoses or any where else that I can see. How easy is it to warp the heads and how easy do the head gaskets start leaking? It seems to run out of water, over heat and there are no leaks to show for it except the water on the head. Please help!

Fill her up with coolant again and start her up. Look down the thermostat housing cover (under the rad cap) and see if the bleeder screw is loose or busted. Also, did you torque the thermostat housing bolts to 110 INCH pounds? Did you make sure the nub in the new thermostat gasket was put in the nook of the thermostat housing cover?

If you are finding coolant on top of the cam cover in the bolt recess (the head bolts are not exposed), check the hose between the reserve tank and the filler neck for a hole. Just a guess, but that was the clue that led me to find the hole in the reserve tank hose on mine. It overheats because it can push coolant into the bottle, with a small amount landing on the cam cover, but cannot create a vacuum to draw coolant back into the system.

Or, Chrome might be right!
