Valve Springs: Inspection

  1. Measure inner and outer valve spring free length. Test valve spring tension with a valve spring tester. Replace springs that fail tests.
  2. Using a flat surface and steel square, check valve spring for out-of-round. Take measurement between top of spring and square, while slowly rotating spring. Out-of-round must not exceed .079" (2.0 mm).
