Keeping unwanted oil away from the combustion chamber is a lot like a balancing act. When you have too little oil, the valve stem's tendency is to wear out easily. But if there's just too much oil, it can seep into the cylinders and ruin the efficient combustion. Fortunately, there's Comp Cams Valve Stem Seal, which keeps the oil at bay with little work on your part. This product makes everything easy, fast, and totally effortless. Available in sets of 16, the valve stem seal from Comp Cams is made of tough and specially-designed Teflon material. It efficiently shuts out unwanted oil in the cylinders by somehow plugging the clearance in the valve guide. Equipping your vehicle with the Comp Cams Valve Stem Seal gives it just the right valve train lubrication that it needs without messing up the combustion. Without a doubt, this product will save you from spending hundreds of dollars worth of repair bills and wasted fuel. Auto Parts Warehouse has the Comp Cams Valve Stem Seal in stock to help you make a smart move when it comes to your car oil concerns.
