Brand-new oil filler tube gasket and washer set for 1986-1987 Buick Grand National, Turbo Regal, and 1987 GNX
The stainless steel washer is an exact show quality reproduction of the original GM washer.
Our gasket is thicker than the original paper gasket and seals the filler tube to the valve cover 1000% better.
Our gasket is also made of Viton rubber for maximum hot oil resistance - NOT SILICONE RUBBER.
Silicone rubber is NOT RECOMMENDED for use with hot oil.
These parts are located between the factory original oil filler tube and stock valve cover. The gasket is heat and oil resistant as well as slightly thicker than original to help hold the filler tube assembly more securely; the bright new stainless steel washer is a great detail item to replace old or missing washers. These parts are purchased in bulk and will ship re-bagged.
