Default Cracked Head Gasket?

2002 Altima, 4 cyl, started using coolant and water. Have now noticed white smoke coming from the tailpipe and some sludge in the oil filler. Have thought and looked at some block sealers like Thermogasket. Is something like this worth the try before replacing the head gasket? Also does anyone know of the best product to use for it? Have not seen any liquid on the ground or in the car from the heater, can only assume its going thru the engine. Also appreciate any do's or don'ts about trying this.
