Check Valve

  1. Detach check valve and blow though it in direction of flow to cylinder head. Attempt to suck back through direction of flow. Replace valve if it allows airflow against direction of flow.
  2. If air pump was inoperative and had signs of exhaust gases reaching pump, a failed check valve would be indicated.
