My Mazdaspeed3 has blueish white smoke come from the hood after i start my car What's causing this

Hello, it's highly unusual for smoke to occur under the hood -- only once, if ever, during a drive cycle. If smoke happens it's a result of a fluid burning on hot exhaust, or maybe even some kind of blowby due to a turbo or PCV system issue. Total wild guess. The best thing to do? Take the car to a shop. Let them check the start up while the problem occurs. They'll see where the smoke comes from and will be able to give you good advice as to how to resolve the concern. www.repairpal.com/repair-shops
