troubleshooting, please help

A 1994 pickup, 22re engine, the truck began to run hot and I could see no coolant leaking. The coolant would blow back out of the resevoir when I removed the cap. I replaced the thermostat and it did not solve the problem. The last night the truck ran, it began to get hot, but I never let it get all the way over to the red line. When I pulled into the driveway, the engine died, so I let it cool down over night. The next morning, I added water to the radiator. Then I tried to start engine, but it would not start. It will turn over. I pulled the plugs and turned the engine over and when I did, water blew from the head. I cleaned the plugs and turned the engine over until there was no longer any water coming from the head. I put the plugs back in and tried to start the engine and it still will not start. The engine is turning over good and there seems to be plenty of compression, but it does seem to have a different sound when spinning over than it had prior to it running hot the last time. Is my problem a blown head gasket and hopefully not any head damage or could I have deeper problems since the engine will not start now. Any help in telling me what to do would be greatly appreciated.

You definetly blew your headgasket usually due to either a stuck closed stat or using aftermarket green Prestone or similar radiator coolant anti-freeze which is high in silicates that commonly promotes corrosion buildup in the tiny water bypass ports/jackets in the aluminum cylinder head and thereby blowing the head gasket more than likely around cylinder # 1 & 4.

You need to resurface your cylinder head as more than likely it's warped which can be verified by setting it on a flat kitchen top counter then you would have to advance your engine base timing by 1 degree to compensate for every 1/1000" th (of an inch) of resurfacing I believe.

To verify my claims do a leak down test and a fluid analysis kit which is available at any Caterpillar dealer around the world or at your local heavy duty mechanic shops that commonly repair bulldozers,backhoes,big rigs and the like.
I would suggest that you quickly drain your old oil before the coolant DESTROYS YOUR CRANKSHAFT BEARINGS thereby making one of the most reliable engines ever made become useless.

Usually in Toyotas when the water pump fails you get freeplay and coolant leak from that area.
