Valve Inspection

WARNING: This page does not describe the selected car, but rather 6 other vehicles, including the 2008 Suzuki Reno, 2008 Suzuki Forenza, 2007 Suzuki Reno, 2007 Suzuki Forenza, and 2006 Suzuki Reno. However, it is still accessible from the selected car via links, so may be relevant.
  1. Inspect the valve stem tip for wear.
  2. Inspect the valve key grooves and the oil seal grooves for chips and wear.
  3. Inspect the valves for burns or cracks.
  4. Inspect the valve stem for burrs and scratches.
  5. Inspect the valve stem. The valve stem must be straight.
  6. Inspect the valve face for grooving. If the groove is so deep that refacing the valve would result in a sharp edge, replace the valve.
  7. Inspect the valve spring. If the valve spring ends are not parallel, replace the valve spring.
  8. Inspect the valve spring seating surface of the valve rotators for wear or gouges. Replace as required.
