While driving white smoke bellowing out front right tire wheel well. Upon inspection, smoke coming from exhaust pipe clamp near turbo. Smell so bad have to drive with window open. It appears engine on fire from the amount of smoke emitting from under the hood. At idle it get worse. It appears smoke is exhaust fumes leaking from the pipe joint. No engine light to indicate a problem.
