Sounds like you found the problem.
But just wanted to say that a head gasket failure doesn't always result in oil or coolant looking bad. It depends on the failure. You can also have oil or coolant making it's way out of the engine or into the combustion chamber.
I believe the friend's 3000gt that he gave me had both of these problems, yet the coolant and oil looked fine and very little was lost. But some (and then more) oil was making it out the front of the engine and then smoking once up to temp. And it failed CA tailpipe smog, likely from one or both getting into the combustion (and also causing O2 sensors to foul). And this engine had bad compression in one cylinder, along with occasionally a terrible sound.
Good luck on your fix.
