Geo tracker help

hey whats goin on guys? ive been noticing a problem with my 95 geo track (85,000 on the dash) --- every time i start it when its been sitting for a long time (overnight or at work) white smoke comes out of my exhuast-- anyone else have this problem?

it is your valve stem seals , when you let the car sit for a bit oil leaks past the seals in the combustion chamber and when you start the engine it is burning that oil off , most cars i have seen with 70,000+miles do it

so if thats the case- how long do i have before something worse happens? is it a costly process to replace the valve stem seals?????????
