Retainer Installation Note

WARNING: This page is about a different car, the 2009 Mazda 6. However, it is still accessible from the selected car via links, so may be relevant.

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 install the retainer to the oil separator.
