Valve Cover Breather

Made from 6061 air craft quality billet aluminum. These breathers feature a premium rubber seal with a heavy duty tab to ensure a tight leak free seal that will last forever. The Breather on the Right is machined with an industry first angle that places the breather level instead of parallel to the top of the valve cover. This helps them drain mist oil back into the valve cover instead of puddling on the low side and leaking outside the breather. Then it leaking onto the header. We no longer make the outdated breather on the left. These are very very nice pieces. Metco has done an excellent job manufacturing these and we love their proprietary designs and quality so much we decided to carry them. Available in ¼ turn lock for the stock valve cover or 1.125" round hole push in style that fits most aftermarket valve covers even non Buick valve covers.
