How to Check a Valve Spring – Inspecting the valve springs on your car is necessary for a complete cylinder head overhaul. Bad or worn out springs will wear valve stems and guides rapidly. If the springs have compressed after years of use, they may cause the valves to clatter, limit your engine rpm’s, and even lead to valve-train damage. These simple tests will help you determine whether new spring valves are necessary before you finish your cylinder head overhaul.
