Feuling Cylinder Head Breathers – M8

Feuling Cylinder head breathers for M8 engines. Machined from billet 6061 aluminum with square surfaces, promoting excellent umbrella valve sealing, longer main breather exit nipples with dual O-rings to promote better breather system sealing. Properly sized breather inlets and location for optimum engine breathing. Unique design maximizes breather volume and allows for easy serviceability. Breather bodies have multiple drain ports located on the inside floor, ports are chamfered on ID to allow easy drainage yet squared off on exits to deter filling from splash oil. Anodized Feuling red.

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 this test procedure can only be performed with a sealed engine meaning no external venting via dipstick or trans top cover.)

NOTES:
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.
