Chrome Bowtie Push In Oil Fill Cap

The Chrome Bowtie Push In Oil Fill Cap from PROFORM is a classic engine dress-up component designed for Chevrolet owners who want authentic factory styling with genuine performance hardware. This push-on oil fill cap replaces worn or missing factory caps and serves as both a functional closure and a visual accent that complements traditional small-block and big-block engine bays. Whether you're restoring a classic muscle car, refreshing a daily driver, or completing a custom build, this cap delivers the iconic Chevy bowtie badge that enthusiasts expect.

This oil fill cap features a durable steel construction with a bright chrome finish that resists corrosion and maintains its lustrous appearance under the hood. The 1-1/4 inch valve cover hole fit is the industry standard for most small-block Chevy applications, and the push-in design ensures a secure, rattle-free seal without requiring threads or fasteners. The embossed Chevy bowtie logo is cast directly into the cap, providing permanent branding that won't wear off or fade like decals. Chrome plating protects the underlying steel while delivering the mirror-finish appearance that separates quality engine dress-up from budget alternatives.

Mechanics and engine builders rely on this cap for both stock restorations and modern performance builds where OEM aesthetics matter. Installation is straightforward—simply push the cap firmly onto the valve cover opening until it seats fully, ensuring the internal seal engages properly to prevent oil splash and aeration. Verify your valve cover hole diameter (1-1/4 inches) before ordering; caps that sit loose or bind indicate a mismatch. This PROFORM cap works on any engine running compatible small-block Chevy valve covers, from original iron heads to modern aluminum aftermarket covers, making it an essential detail for finishing any Chevrolet engine build.
