okay my car overheated on the side of the road on cheristmas day and there was smoke EVERYWHERE well the head hadnt blown but the mechanic said he replaced an intake gasket, well now she overheats all the time at least that is what the gauge says. HER WATER IS NOT LEAKING OUT ANYWHERE BUT IT IS GONE WITHIN AN HR OR SO AFTER WE FILL IT UP. they have found no leaks or holes and the water is basically disappearing...her oil and water is not mixing and we check constantly? wtf is going on?
