White smoke is usually a sign that water is getting into the combustion chamber... the culprit may be the head gasket... but i guess a pressure check wouldn't hurt.

Agreed.
Head gaskets blow for a reason. If your buddy changed the gasket but did not fix the root problem, such as a warped head or block, the gasket will blow again.

I think the water pump on it not working or its clogg and I did change the thermostat in thought that might of been the problem with water not following through the radiator. My buddy toke the heads in had them reconditon 2 years ago the full work . That why we are stuck on this problem
