Lots of smoke started coming out of my 95 4runner.

I bought K&W Nanotechnology Head Gasket & Block repair and followed the directions really well.

I removed the thermostat, flushed the radiator. Let the repair sit in for 12 hours. Flushed the radiator again but I still have a good amount of white smoke coming out the exhaust although its not as much as it was before.

It doesnt happen right away, only once the engine is warm.

And ideas of what else it might be if not the head gasket?

 

Lots of smoke either has to be fuel or coolant. What does it smell like?
