Car seems to be running fine but produces white smoke from the exhaust (could be steam) under harsh acceleration. Usually it will do this at normal engine temp and when i have driven normally for a while then floor it. Performance is not affected and car has only 18k with full service history. I seen another web post elsewhere saying this is common on a 182 where water condensation builds up in the exhaust under normal driving conditions then releases it into steam when floored. Can anyone verify this????
