What does the valve spring do in a car?
A valve spring is placed around the stem of a valve and held in place by a retainer. Its main job is to control the entire valvetrain, ensuring that the proper amount of spring pressure is applied consistently to prevent valve bounce.
What causes broken valve springs?
What Can Cause Valve Springs To Fail. To maintain correct valve operation at normal engine speeds; all of the valve springs must exert a certain amount of spring pressure. Consequently, too low or week valve spring pressure; may cause valves to not completely seal or float under higher (RPM).

How often do valve springs need to be used?
Continuous use makes every part wear, and the same is the case with the valve springs. These springs function almost 70,000 times in an hour when it comes to high-end engines and that way trillion times in their life.
How are valve springs used in a car?
The springs make the valve function for opening and closing during combustion cycles. This way, the valve springs determine the right closing and opening time of the valves responsible for doing the fuel intake further and making the driving happen. Continuous use makes every part wear, and the same is the case with the valve springs.
How can I tell if my valve springs are broken?
Diagnosing Weak Or Broken Valve Springs With A Vacuum Gauge. To narrow down the list of possible causes of your engine performance problem; connect a vacuum gauge to a vacuum port on the intake manifold. Then start the engine and observe the vacuum gauge readings; at idle and at progressively higher engine speeds.
What happens when a valve spring goes bad?
When this pressure is inaccurate, it creates the possibility of getting worn quickly. When a valve spring goes broken, it causes drivability and performance problems. You also hear the valve noise, and this overall causes serious damage to the engine.
How can I choose the best valve springs for my car?
Companies like PAC Racing Springs have sophisticated software, Spintron test equipment, and the experience to help determine the optimum spring selection.” Jack McInnis, of Erson Cams, stated, “There are a number of factors involved in selecting the optimal valve-spring setup for your engine.
What is the pressure of the valve springs?
Valve Springs The valve springs also push back against all the other parts like the rocker arm; pushrod and lifter to maintain pressure on the cam lobe. In most stock engines; the pressure exerted by the valve springs when the valves are closed, is around 85 pounds.
Continuous use makes every part wear, and the same is the case with the valve springs. These springs function almost 70,000 times in an hour when it comes to high-end engines and that way trillion times in their life.
