94 7.3 factory turbo. When in overdrive sounds like a terrible exhaust leak above 2000 rpm. If I'm in neutral and rev it to 2000 rpm I never hear it. Could this possibly be something else? I have replaced the pump and injectors. Also I have an oil leak that will not go away. 2 rear mains and an intake manifold gasket and still leaks.
