Metco Motorsports MBR0005 02+ Ford Modular V8 Valve Cover Breather

This valve cover breather assembly replaces the original oil fill tube found on the factory passenger side valve cover. The base is CNC-machined from billet aluminum for precise fit, and the included silicone O-ring is specially designed to prevent oil seepage at the base of the breather. The filter base is microfinished for surface protection and good looks, and is easily hand-polished to a mirror-like appearance. The removable filter element is a high-quality, USA-made reusable unit, and it is securely retained in the filter base by a specially machined retention groove at the top of the base.

The purpose of this valve cover breather is to vent unwanted accumulation of pressure in the crankcase, which serves to eliminate pumping losses and reduce oil temperatures. The installation of this breather will contribute to increased engine oil life and reduce the possibility of failed engine seals resulting from excessive crankcase pressure.

The included check valve will allow the breather to vent any crankcase pressure that accumulates, but it will not allow ambient air to be drawn back into the engine through the breather under high-vacuum conditions. This valve is beneficial for applications that retain a valve cover vent line, or applications with a very sensitive (or aggressively-lean) PCM calibration.
