{"product_id":"n54-external-pcv-kit","title":"N54 External PCV Kit","description":"The RB N54 External PCV Kit is a low-side system developed in 2015, offering a solution to common issues arising from high-performance N54 engines or component degradation. Problems like oil consumption and exhaust smoking can often be traced to an OEM PCV system that is no longer up to the task, or to issues like clogged valve cover ports and hardened valve cover gaskets.\n\nThis kit allows for the integration of an Oil Catch Can (OCC) into the low-load system, preventing oil accumulation on intake valves. By inserting an OCC, you can capture this buildup, which typically occurs during everyday low-load usage through the internal PCV valve, and see it accumulate in the can instead of on your valves.\n\nFor optimal performance, it is recommended to plug the head ports, which eliminates vulnerabilities in the valve cover gasket and valve cover. However, plugging the head ports is not a mandatory requirement to run the kit. The kit is designed for dedicated, high-performance, and maintenance-savvy N54 consumers.\n\nRB offers the kit in various options (A, B, or C, and \"PNP\" or \"Non-PNP\") to minimize excess parts and costs. Option A \"PNP\" is the most comprehensive recommended kit and includes a dual-port throttle body adapter that can also serve as a BOV\/Diverter reference. \"Non-PNP\" kits omit the custom throttle body adapter and include an NPT bung, requiring the user to improvise a vacuum reference interface, typically by drilling and tapping the intake manifold.\n\nImportant compatibility notes include: This kit is not compatible with the standard RB PCV Valve and Cap, as they are internal arrangements and must be removed. RB recommends Mishimoto Oil Catch Can offerings (MMBCC-MSTWO-BK for 3\/8\" NPT or MMBCC-CBTWO for M16x1.5 with O-Ring). An RB OCC Support bracket is available for BMS and Mishimoto OCCs, compatible with 135\/335 and M3 strut bars, but not with the 5 series strut bar.","brand":"RB Turbo","offers":[{"title":"Default Title","offer_id":52689355997496,"sku":"RB-N54-PCV-EXT","price":70.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687605425.jpg?v=1784905624","url":"https:\/\/store.motormia.co\/products\/n54-external-pcv-kit","provider":"MOTORMIA","version":"1.0","type":"link"}
