Test the coolant for gas that leaks from bad head gasket, O'Reilly's loans free test kits...

You will fix it oorah ;^)
Correct, it's the V6. I have a friend I race dirt bikes with that happens to be a Toyota master tech. He's going to let me use his fancy leakdown tester this weekend. He mentioned the same trick with the oil in the cylinder to see if it's the rings or not. I think it's worth saving the engine as long as it's anything but cylinder bore/ring damage. If it is I'll start looking for another engine. This truck is just too damn cool to let it die.
