Mishimoto (MMBCC-CSS-10P): PCV-Side Baffled Oil Catch Can for ’10-’15 Camaro SS

The LS3 and L99 engines fitted to the 5th Gen Camaro SS generate more than 400+ HP from their eight cylinders. But they produce something a little less desirable, too: blow-by. Oil, fuel, and other by-products of combustion squeeze their way past piston rings with each stroke. Left unchecked, this material can rob your Camaro of power and efficiency.

The air diverters and internal baffles in Mishimoto’s direct-fit catch can kits help slow incoming air, condensing oil, and fuel vapors, while a 50-micron bronze filter prevents further blow-by from escaping into your intake. The MMBCC-CSS-10P mounts via a custom-fit bracket without any drilling or cutting required. Direct-fit lines, complete with quick-disconnect fittings, mate our can to your factory Chevy PCV system for an easy and seamless install.

These Mishimoto catch cans are different from most air-oil separator (AOS) systems in that they are not heated, meaning all of the blow-by can condense in the can—including low-octane oil vapors and contaminated fuel vapors. Second, many AOS systems also drain the blow-by into the oil pan, while Mishimoto’s trap the blow-by and keep it out of the engine permanently.
