Frequently Asked Questions (FAQs)

1. What is the proper valve seating?

Proper valve seating involves having the valve seat at the correct width, location on the valve face, and being concentric with the guide. Automotive engines typically have an ideal seat width of 1/16˝ for intake valves and 3/32˝ for exhaust valves. These factors ensure a proper seal and optimal engine performance.

2. Are engine valve seats replaceable?

Yes, valve seats can be replaced if they are pitted, chipped, or too damaged to re-cut. Replacement is also necessary when the seats have been cut multiple times and are now too deep, affecting proper valve clearance. Replacing the valve seats helps maintain engine performance and prevent issues related to valve leakage.

3. How do I know if my valve seats are bad?

If you are experiencing issues with water dripping from around the handle area of a faucet, it could indicate a bad valve seat. The valve seat is located directly beneath the washer that controls water flow. When the valve seat is damaged, it can cause leaks even when the faucet is off.

4. What causes valve seats to go bad?

Valve seats can deteriorate due to high and low temperatures, pressures, or a combination of both. These factors can affect the durability, functionality, and longevity of the valve seats and valves. Failing to consider these factors during manufacturing can lead to premature failure of the valve seats.

5. Do valves need to be seated?

Yes, valves need to be properly seated for optimal engine performance. If the valve seat is improperly positioned, oriented, or formed during manufacturing, it can result in valve leakage. This can negatively impact the engine's compression ratio, efficiency, performance, and exhaust emissions.
