Engine valve springs are an essential component of any combustion engine. They are responsible for ensuring that the valves open and close at the right time during the engine's operation, allowing for proper fuel combustion and exhaust flow. These springs are made from high-quality materials such as steel or titanium, and are designed to withstand the extreme temperatures and pressures that occur within an engine. They come in a variety of sizes and strengths to meet the specific needs of different engines, and can be easily replaced when necessary. Without reliable valve springs, an engine's performance and longevity can be severely compromised.

Frequently Asked Questions (FAQs)
1. What do valve springs do in an engine?
Valve springs in an engine are responsible for keeping the valves closed. They exert pressure against the valve retainer to maintain the valve's closed position. Each valve within the cylinder head is equipped with at least one spring to ensure proper valve operation.
2. What are the symptoms of bad valve springs?
When valve springs become weak, several symptoms may occur. These include flattened engine RPM, popping through the intake or exhaust, valve springs hitting the valve seat and bouncing into the piston, or simply breaking.
3. What causes engine valve springs to break?
Valve springs can break due to bending stress when compressed, especially if there is valve duct channeling during use. Loose camshaft bearings can also cause valve springs to resonate and lead to breakage.
4. Can you drive with a bad valve spring?
Driving with a bad valve spring is not recommended. It can result in reduced engine performance, abnormal engine sounds, worsened fuel economy, and potential damage if broken valve springs send metal chunks into bearing journals.
5. Do new valve springs add horsepower?
Choosing the right valve springs with the correct seat pressure, open pressure, and spring rate for the camshaft can improve engine performance. By selecting the proper springs, it is possible to gain free horsepower for your engine.
