Valve spring installed height is the distance between the valve spring seat and the top of the valve spring when the valve is closed. It is an important measurement because it affects the valve train’s performance. If the installed height is too low, the valve may not open fully, which can lead to a loss of power and efficiency. If the installed height is too high, the valve may not close fully, which can lead to burned valves and other problems.
There are a few different ways to check valve spring installed height. One way is to use a dial indicator. Another way is to use a spring tester. Both methods are relatively simple and can be performed in a home garage.
