ok... heres the deal... everytime i start my car after it has been sitting for a couple of hours, a huge cloud of white smoke comes out the exhaust, but if it is only sitting for like 20 minutes it doesnt do it. anyone know why it does it and how to fix it?

valve guide seals need to be replaced

how much is that gonna cost me?

White smoke is NOT valve seals! could be head gasket? are you losing coolant?

he probably didnt mean paper white or anything. i bet it is the seals. you can replace them yourself, its the best way to gain experience
