Metco Valve Cover Breather LT1, GM TPI, Vortec (with Screw Mount) Metco Valve Cover Breather LT1, GM TPI, Vortec (with Screw Mount) Metco  This valve cover breather assembly replaces the original oil fill tube on the factory 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 reusable unit from S & B Filters, and it is securely retained in the filter base by the 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, and to provide maximum circulation of ambient air in the crankcase to 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. This breather will reduce the effectiveness of the vehicle's PCV system, and it is not emissions-legal. Note: This breather stand is also available with a male #10AN connection at the top instead of the provision for the breather element. This configuration is designed for use in a custom crankcase evacuation system or for use with a vacuum pump.
