White smoke?

MAZDA 929

I have a 92, v6, Mazda 929, it has about 133,000 miles on it. The problem I am having is alot of white smoke coming from the exhaust, and when I press on the gas there's what looks like a spurt of water coming out. Ive checked the oil, trans fluid, and radiator fluid and nothing appears to have a milky color to it. Along with it occasionally overheating, it's also making a knocking sound. What could be the problem?

Could be the headgasket is blown or crack head or block get it tested see below

Have it block and pressure tested-do the block first to pinpoint a combustion leaking into the cooling system or a gas analyzer to sniff for hydrocarbons at the radiator fill neck.

Pressure test: do not do a pressure test if there's leakage at the headgasket this might cause coolant into the cylinders and lock it up or bend a connecting rod if cranked thereafter. The headgasket should be repaired before doing the pressure test.

If the block and pressure test passes check the following: Thermostat, Pressure test the Rad. Cap, Clogged radiator, Fan clutch, Radiator electrical fan, collaspe hoses, water pump.

Good Luck
