O’BRIEN TRUCKERS now offers these ultra-cool valve cover breathers patterned after the ones released by G-T Equipment in 1964, featuring a distinctive 4-fin design. Add your own color between the fins for extra detail, as shown, and they really “pop”. The improved version is updated with a removable cover and open cell foam insert to keep the oil inside the valve covers. The mounting surface area is 7-1/2" x 1-1/4", and the removable top cover measures 8-1/4" x 1-3/4". The breather assembly adds only 2-1/4" to the side of the valve cover, and the height is 3-1/8". Each breather comes fully polished with stainless steel mounting hardware and a custom die-cut gasket to properly seal it to the valve cover surface. You’ll find them featured on O’BRIEN TRUCKERS’ new website, along with a truckload of other period-correct nostalgic products.
