Valve Cover Adapter for Modular Ford Applications

PCV-Style, Twist-in Helix


This valve cover adapter is designed to fit the cam cover port found on some Modular Ford applications using the helix (twist-in) PCV valve.  This unit can replace the factory-installed PCV valve in many 4.6, 5.0, and 5.4 applications.  Please see details below.

The adapter is CNC-machined from billet, vibratory-polished for a long lasting finish, and fitted with the appropriate silicone o-ring.  

The total adapter length is 1.75", and the OD of the knurled portion is 1.50".  This adapter was originally designed for the early Modular applications, and later OEM cam covers fitted with the 'Powered By Ford' emblems will require significant modifications to use this part.  Please ensure proper fitment for your application prior to ordering, and feel free to call or email if you have questions.

Images 4 & 5 (above) shows this breather installed in a 2V cam cover.



Important Notes on Fitment:  The twist-in helix base of this breather is 0.575" in length, and the total length of the adapter is 1.75.  It is the 1.50" OD knurled portion that may interfere with the OEM cam covers in some applications, especially 5.0 4V Coyote engines.
