When do weak valve springs cause a problem?
When do weak valve springs cause a problem?
If weak valve springs are causing your problem; the vacuum readings on the gauge will oscillate as engine speed increases. However, a rapid vibration or variation in the vacuum gauge reading at increased engine speed; can also be caused by:
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.
What should you know about stock valve springs?
Valve Springs: What you should know about them. 2. Stock springs can coil bind when used with high lift performance cams. 1. Stock springs can loose control of valves when hi-revving performance cam is installed.
Can a stock valve spring be used on a high lift camshaft?
In most cases stock valve springs do a good job for stock camshafts. When changing to a high lift Crower performance camshaft, stock springs physi- cally won’t travel the distance your Crower high lift camshaft requires. The spring coils stack solid and the destructive condition called COIL BIND exists.
