Greetings all

Recently my temp gauge began to creep up, so one morning I checked coolant level. Overflow tank empty. Filled it, next morning empty again, I fill it. Same thing now every day for almost a week. I also notice now white wispy vapor from tailpipe when cold. Does this sound like a head gasket? That's what I'm thinking, any other possibility (please no cracked block!).

Now gaskets, Scan Tec from FP Groton? Or is Elring better? Does it make a difference? Procedure looks pretty regular per overhead cam engines, any special trickery?

Thanks
