Retainer Installation Note

CAUTION:

Be sure to replace the old retainer with a new one to prevent the escape of blow-by gas. Reinstalling the old retainer will reduce airtightness.

Make sure that the retainer alignment mark is directed as shown in the left diagram before installing the retainer to the oil separator.
