- Oil filler tube A90283
- Oil filler cap A90003
Cap and tube were supplied by an outside vendor and received painted black. The caps have been black or cadmium plated.
They were inserted in the engine block when it was painted. It is believe that these left the factory engine green, but the black is found under the green over time.
For now in judging green or black are both acceptable.
