      Tech Tips

      The intake valve oil seal is gray and the exhaust valve oil seal is black.

      Note

      Pay close attention when installing the intake and exhaust oil seals. For example, installing the intake oil seal on the exhaust side or installing the exhaust oil seal on the intake side can cause installation problems later.

  5. INSTALL INTAKE VALVE
