FEULING breathers work, seal and you will find they hold an engine vacuum. Testing shown on a healthy engine will see 3-4 oz of oil in the sump and once the dipstick is removed another 3-4 oz will drain. NOTE: for this test no external venting can be used, meaning a sealed dipstick and trans cover must be used.
1 Year warranty with option for an additional year if warranty form is filled out on website.

The Factory plastic OEM breathers can be problematic, we find the material easily distorts, especially after seeing excessive heat then the internal umbrella valve struggles to seal, causing oil carry over. Another issue found with the OEM breathers is cracked and or broken exit nipples which can be caused by heat distortion and or improper fit and poor installation.
