The service manual cross-references the Ultra Gray.

either. some engine builders say that stuff is a rip off and they use straight GE 100% silcone II for anything from valve covers to oil pans. I've had success using the Ultra Copper, never used the Ultra Grey.

Off to the Engine/turbo/drivetrain. Thats the proper place to ask questions about the diagnosis/repair/modding of your Evo.
