COMP Cams offers a complete line of valve seals, from the stock GM O-rings to the positive-stop PTFE seals. They are a must to keep unwanted oil from entering the combustion chamber through the clearance in the valve guides. The O-ring seals use the standard retainer and oil splash shield. The umbrella seals are normally used when a larger-than-stock diameter spring is used. In the case of a double spring, the positive stop PTFE seals are used. For triple-spring applications, use the smaller-diameter Viton seals.

Great Chew & Flavor
Size: 1 Count (Pack of 6)
My dogs chow down on these great crunchy/crispy snacks. Great for light to medium chewers. My intense chewer loves the flavor...but he can get through one ear in less than 20 minutes (on a relaxed day).

My dog loves these pigs ears, she's a 20 lb Shih Tzu Jack Russell mix, I cut the ears in half but they're still going within 10 minutes.
