My engine builder order every seal imaginable. They all looked the same. Must be the same mold now for every manufacturer. If you find a different variant,pass it on.
They are all the same, save for the material. I am only referencing the RED one here. Big deal--they may hold up better in a severe high heat situation but then you have other problems. Believe me I was fantasizing about machining another groove in the block and machining a dedicated retainer to double up the seals at one point. Scary thing is I was this close to doing it--'cuz I can. J.Rob
