These can stop functioning properly if there is excessive oil blow by. 50k is a good interval. Cheap maintenance.
Good point. Someone over on the Honda Pilot forum claimed that one broke leaving some of it inside. Likely never had been replaced. Age and milage old. This is one of those parts that plays an important role in keeping the pressure inside the engine at a normal level. Bad stuff happens when it doesn't work properly. 50k miles is likely to soon. Soon is better than to late.- just be careful prying the old one out. Btw my old one didn't appear to need changing.
