Fig. Fig. 1: Check the valve spring for squareness on a flat surface; a carpenter's square can be used

  1. Place the valve spring on a flat surface next to a carpenter's square. Measure the height of the spring, and rotate the spring against the edge of the square to measure distortion. If the spring height varies (by comparison) by more than 1 / 16 in. (1.6mm) or if the distortion exceeds 1 / 16 in. (1.6mm), replace the spring.
  2.  
  3. Test the valve springs for correct spring pressure at the installed and compressed (installed height minus valve lift) height using a valve spring tester. Springs should be within one pound, plus or minus, of each other. Replace springs if they do not meet the specifications shown in either the Valve Specification or Engine Rebuilding SPECIFICATION CHARTS.
