If you mean Teflon encapsulated silicone O rings, I have used them and they work fine. The engine has about 3000 miles on it so I don't know how long they last, but I doubt they will give any trouble. Teflon has superior chemical resistance compared to raw silicone, which is what the stock seals are.

I have them, and I love them. I had an engine fail before when I hit something in the road and it busted my radiator. The sudden loss of coolant just cooked the stock seals, even though I turned it off almost immediately.



This rebuild, Ive had similar experiences 3 times(sudden coolant loss), but I was much harder on the engine. The engine hasnt missed a beat. The teflon seals have saved me a few times already.

The stock seals have a teflon lining on the side that faces in towards the combustion chamber. But it does no good when the supporting material behind it fails from the heat.
