What is a Valve Tire?
For internal combustion engines to work properly, they need the right amount fuel and air. Any disruption of this mixture can lead to engine damage and performance problems. Different gaskets can be used to keep the liquid components and air out of the engine. Valve rubbers are also known as “Valve stem seals.” Or “valve seals” . The engine’s efficiency is directly affected when the valve tires are in place. These tiny seals prevent oil from entering the combustion chamber and prevent oil from getting into the cylinder head.
The valve stem is found under the valve springs of the engine’s head. The valve rubbers control the amount of oil in the valve stem (also called the valve guide) and regulate its temperature. Insufficient lubrication can cause the guide and valve stem to wear more quickly due to friction. Excessive lubrication damages the valve seat and causes carbon accumulation, which in turn increases vehicle emissions.
There are two types of valve stem seals available. “deflector seal” “positive seal” . Also known as: “umbrella seals” By removing oil from the stem of the valve, you can prevent excess lubrication. Attached to the valve guide, positive seals act as a squeegee and measure oil passing through the seals.
Valve tires have an inner diameter that fits into the valve stem, and an outside diameter that fits into the valve guide. It acts as a seal between the crankcase & the combustion chamber to prevent contamination or leaks.
What Materials are Valve Tires Made From?
Valve rubbers are made from a variety of materials, including nylon, polytetrafluoroethylene rubber (also known as Teflon), steel, and synthetic rubber. These materials can all be combined to make valve tires. Valve tires are usually equipped with small springs to allow them to rest securely on the cylinder head.
Why do Valve Tires Lose Their Value?
There are many factors that can lead to valve rubbers failing over time. The most common reasons are:
- Regular oil changes can cause engine oil and filter to be prematurely damaged.
- – May malfunction due to incorrect installation
- – Gaskets made from sub-industry or poor quality materials can cause premature failure.
What are the symptoms of a valve tire failure?
One or more of these symptoms may be caused by a defective valve tire. The most common signs of valve rubber failure are:
- Blue smoke coming from the exhaust is the most obvious sign of a damaged or loose valve tire. The valve cap can get clogged up with oil from previous drives if the vehicle is not used for longer periods of time or is not turned on overnight. The damaged gaskets trap oil in the combustion chamber, causing bluish smoke. This is a sign that your valve tires need to be replaced.
- Damaged valve trains can also be indicated by high oil consumption. Engine oil will quickly run out if engine rubber is damaged. This can lead to engine oil seeping into the combustion chamber. Other faulty parts can also lead to oil consumption. A thorough inspection of your engine is necessary.
- Engine braking can also be used to detect rubber failure. When going downhill, the engine brake should be used for a while before pressing the gas. This will cause the oil in the valve cover to leak into your combustion chamber. Excessive smoke is produced by the exhaust because engine oil burns more slowly than normal.
- Leakage of valve rubber can lead to valve seats failing, increased carbon buildup and even damage to the catalytic converter. Unburned fuel in the exhaust can quickly increase the catalyst’s operating temperatures, which can lead it to overheat and clog its exhaust.
- Oil contamination and carbon buildup can be caused by damaged valve rubbers. This can lead to engine misfires and can affect the ignition of spark plugs.
- Low engine performance and poor acceleration are the last signs that your valve tires may be defective. To determine if the valves are damaged, you can test the compression of your engine. The problem is with your valve tires if the engine compression level is high. If the engine’s compression is low, it could mean that the piston rings are leaking. Both of these malfunctions can have similar symptoms. However, it is important that they are not confused.

When is it time to change valve tires?
If you take care of your vehicle, your valve tires will last for an average of 250,000km. It is important to keep your engine oil changed on time. You also need to use an engine oil that has the right viscosity. Regular oil changes can also help protect your engine and reduce friction.
