8.3l Cummins exhaust manifod question
After all I've read about exhaust manifold leaks on a 6C 8.3l (11/93 production date in my coach ) is to replace the one piece manifold with a two piece manifold.
I called Rocky Mountain Cummins-Las Vegas and was told that there is no two piece manifold for my motor. Is this true or is my engine to old to have service bulletins in their system?
My issue is that I have leaks at the head mounting surface and at the turbo. I'm not sure if the manifold is cracked or not, but I figured it would be a good time to replace it with one that is supposed to be an improved design since I have to take it apart anyway.
