Description
Product Overview
Pirate Mfg presents a precision‑engineered PCV and valve cover breather kit crafted from high‑grade aluminum with a mirror‑polished finish. The material choice provides excellent resistance to corrosion while maintaining a lightweight profile that won’t add unnecessary mass to the engine bay. The rounded, finned design not only looks striking under the hood but also promotes efficient airflow, helping to regulate crankcase pressure and reduce oil vapor emissions during high‑performance operation.
Each kit is tailored for vehicle‑specific fitment, targeting the common 1‑1/4 inch valve cover opening found on many classic and modern performance engines. The included silicone‑rubber grommets are engineered to accept a 7/8 inch vent stem, allowing the breather to be installed on a wide range of aftermarket and stock valve covers without the need for additional machining. The kit arrives as a single piece, fully assembled, and ready for immediate installation.
Beyond its functional role, the breather kit is designed for easy maintenance. The finned aluminum housing can be detached in seconds, granting full access to the internal filter element for cleaning or replacement. This modular approach extends the service life of the component and ensures that the engine continues to breathe freely, even after extensive track use or prolonged street driving.
Visually, the polished surface reflects the surrounding engine components, adding a premium look that appeals to enthusiasts who value both performance and aesthetics. Whether mounted on a rat‑rod, hot rod, muscle car, or a custom build, the kit enhances the overall engine bay presentation while delivering reliable crankcase ventilation.

Usage
This breather kit excels in environments where engine performance and reliability are paramount. It is an ideal upgrade for street‑legal hot rods that demand consistent power delivery, as well as for track‑day racers who need precise pressure control to prevent oil blow‑by during aggressive acceleration and deceleration. The kit also serves custom car builders who prioritize a clean, polished engine appearance for show‑quality builds.
Installation is straightforward: the kit replaces the factory breather or PCV outlet, and the included grommets ensure a snug seal around the vent stem. Because the kit is made from aluminum, it tolerates the heat cycles typical of high‑output engines, making it suitable for both naturally aspirated and forced‑induction applications. Users have reported improved throttle response and reduced oil consumption after fitting the breather, especially in engines that previously suffered from excessive crankcase pressure.
For maintenance, simply remove the finned housing, clean the internal filter element with a mild solvent, and reassemble. The design allows for quick inspection after each service interval, ensuring that the breather continues to function at peak efficiency throughout the vehicle’s life.

FAQ
Will this breather fit my 1970 Chevrolet Camaro?
Yes, the kit is designed for the standard 1‑1/4 inch valve cover opening found on many classic American V8 engines, including the 1970 Camaro. The included grommets adapt to a 7/8 inch vent stem, which matches the factory vent size on that model.
Can the breather be used on a forced‑induction engine?
Absolutely. The aluminum housing tolerates the higher temperatures generated by turbocharged or supercharged setups, and the finned design helps manage increased crankcase pressure that can occur under boost conditions.
How often should I clean the breather?
We recommend inspecting and cleaning the breather at each major service interval, typically every 5,000 to 7,500 miles. If the vehicle is used frequently on the track, more frequent cleaning may be beneficial to maintain optimal airflow.
What is included in the package?
The package contains the polished aluminum breather housing, a set of silicone‑rubber grommets sized for a 7/8 inch stem, and a detailed installation guide. No additional tools are required for installation.
Is there a warranty on this product?
Pirate Mfg offers a limited one‑year warranty covering material defects. If you encounter any issues related to manufacturing quality, contact our support team for a replacement or repair.
