I don't want to beat a dead horse when it comes to direct injection but is this sound normal? Truck just started making it at 12k miles. 2016 5.3. Sound appears to be coming from mid to top end of rear side of engine. Way louder than it's ever been. Sound is really loud at cold start and doesn't really go away when its warm. It's never made this sound until this weekend.
