[Mobile-Portable] Fwd: Injector Noise Cures

[N5WV]

Group , Has anyone had much success defeating injector noise with Ford 6.0 and 7.3 ltr diesel engines ? I have bonded the exhaust system , doors and hood of my Excursions plus added extra engine ground straps and power directly from batteries and injector noise is still present. And have added mix 31 toroids on every power lead and coaxial cable . I have purchased copper foil and copper tape for shielding injector wiring harnesses outside of the engine and have not had the time to do it yet. I thought about snap beading the injector leads but they are enclosed under the valve covers with other parts in the way. And they are very tight with no slack at all. So if it was worth pulling the valve covers and oil rails one could not wrap the bead at all. For now , all I know to do next is start shielding external wiring harnesses with copper foil and copper tape. Anyone have any other ideas ? Randy N5WV
