ok so first I replaced the water pump and thermostat both were necessary (water pump only had 3 fins on it out of i believe 9 or so and there was no thermostat in it) still losing coolant then I replaced intake gasket and ran a cold compression test all but 3 cylinders were dead up at 150 very front passenger side cylinder was 3-4psi low the third cylinder from the front passenger side was 2-3 psi high and one on drivers side was 2-3 high i am still losing coolant no water in oil no crystallization on spark plugs found where it is dripping on passenger front of exhaust manifold however I couldn't see where its coming from examined around the intake with a light and cannot see any water anywhere around it or in the valley of the block please help also it leaked about 2 ¼ gal in a day given i drove about 130 miles the leak i found doesn't seem to be more than about what ac condensate is normally slow drip

 

see if it is running out of the bell housing between the motor and the transmission... There are a couple freeze plugs on the backside of the motor and may have a pin hole from corrosion.

 

see photo in first post below.. You may have a different motor, but similar plugs

Assuming it's a 4.6 or 5.4 these engines are notorious for leaking cross over on the intake manifold and engine valley coolant line to heater core line.

 

I am going with cracked crossover, everything you have is classic of it. Prone to cracks behind the thermostat.
