The file 'Lincoln 5.4 DOHC COP Cover Rubber Washer 3D Printer Model' is (stl) file type, size is 11.3KB.
The original cop cover bolt on a Lincoln 5.4 DOHC does not cover the whole face and corrosive fluid debris eat and pit the bottom. I deigned a rubber washer that fits the hole and uses an additional stainless washer to spread bolt head load. Makes the plated coil over plug cover look nicer.
washer recess is designed for a M6 x 18mm OD stainless.
