If it isn't leaking out on the ground, then it is coming out the exhaust as vapor. Get it fixed before you overheat the motor and cause more damage. Is isn't going to get cheaper or fix itself.

When was your last headgasket, how many miles ago?

My 3.0L just got a new headgasket this year, one replaced by Toyota and the rest from the current owner <img src="/forums/images/graemlins/baby.gif" alt="" />
