Need help with a Ford engine, NOT an FE?
My son has a 1996 Mercury Mystique with the inline four cylinder Zetec engine. It started to over heat last week after drive if about 5 miles. I change the thermostat and then the water pump, but it still does it. I thougt maybe it was a bad head gasket blowing exhaust into the coolant. I did a compression test and they all were 120 psi. Now I baffled, I know if could possible be a cracked block, is there a way to check if the block is cracked other than tearing it down? Does anyone else have any other suggestions of what to look for?
Any help greatly appreciated.

I am no expert on the new engines - but I have never seen a cracked block, cracked head, or blown head gasket that did not show some of the standard symptoms - water in the oil, oil in the coolant or exhaust gas in the radiator, or a dead cylinder in a compression test.
I would be looking elsewhere for a problem - the rest of the cooling system, the timing, or a restricted exhaust system.
