The PROFORM 141-754 is a push-in valve cover breather built for Chevrolet engine builds and street rods that need crankcase venting without a cluttered look under the hood. It measures 3 inches across, stands 2.50 inches tall, and drops into a standard 1.22-inch (1-1/4 inch) valve cover hole. The black crinkle finish and raised Chevrolet Bowtie emblem give it a finished appearance on small-block and big-block valve covers alike. Anyone running an open or aftermarket valve cover that needs a vent point will find this a clean, direct-fit answer. Browse the full engines and components lineup for matched parts.
PROFORM stamps this breather from steel and coats it in a textured black crinkle finish that hides fingerprints and shrugs off underhood heat. The 1.22-inch press-fit base seats firmly into a 1-1/4 inch grommet or valve cover opening, holding position without hardware. The overall 3-inch diameter and 2.50-inch height keep it compact enough to clear hood lines on most builds while still flowing enough air for crankcase ventilation. The raised Bowtie logo on the top face marks it as an officially licensed GM Performance Parts product, so the styling matches factory and aftermarket Chevy dress-up components. PROFORM backs the breather with a 30-day limited factory warranty per the supplied product data. It pairs naturally with vented valve cover setups.
Reach for this breather when a Chevy build runs a valve cover with an open vent hole and you want the crankcase to relieve pressure cleanly. It works well on engines that route one valve cover to a breather while the opposite side handles vacuum routing, a common setup on carbureted small-blocks and big-blocks. The push-in base means no threading or clamps to fuss with during assembly. If you are dressing an engine, check our oil breather cap options and the breather element selection to complete the venting and oil fill side of the build.
