Renegade Racing Billet Valve Cover Breathers with Dual Baffles

There’s a problem almost every serious builder runs into sooner or later—how to properly vent crankcase pressure without making a mess, losing oil, or welding on a bunch of fittings. We’ve seen it a hundred times. So, we fixed it.

At Renegade Racing and Performance, we don’t just build fast cars—we engineer elegant solutions for the gritty, overlooked problems that cost you power, consistency, and time.

These billet valve cover breathers—also known in the pits as burn down tubes—are machined from high-grade aluminum and bolt in place with no welding required. Just a flat spot on your valve cover or valley tray and a few minutes of your time. That’s it. You’re done.

Here’s what makes our system different (and better):

• Dual Baffle Technology – An internal baffle and a low-profile external baffle work together to strip oil from crankcase vapor before it even reaches your catch can.

• Less Oil Blow-By – That means your catch can stays cleaner, longer.

• Weld-Free Install – No TIG? No problem. Our included drill guide and O-ring sealed design let you bolt these breathers in without any welding or RTV guesswork.

• Versatile Fittings – Each unit is tapped for -10 ORB, allowing quick adaptation to 8AN, 10AN, or 12AN with your preferred fittings.

• Low Clearance? We Thought of That. – If you're running tight valvetrain geometry, the internal baffle alone will still get the job done without interference. But when possible, run both baffles for maximum oil separation.

This isn’t some universal gimmick. This is a purpose-built burn down breather system, designed for race cars, street machines, and boosted setups that demand efficiency and durability without the extra mess.

And of course, every detail matters. That's why every kit comes complete with low-profile button-head bolts, an O-ring pre-installed, and a drill guide that ensures a perfect install the first time.

One last thing—use red Loctite on all hardware. Always. This isn’t a suggestion—it’s the difference between a clean race and a surprise teardown.
