Show original supplier description
The BMS Vacuum Side Oil Catch Can Kit is engineered to work in conjunction with the boost side N54 oil catch can to prevent engine oil and PCV gunk from coating your intake valves and diminishing engine efficiency. This system specifically targets oil separation during engine vacuum operation, such as idling and low throttle conditions, complementing the boost side's function during heavy throttle. When used together, these kits provide comprehensive protection, ensuring oil does not coat intake ports and valves throughout all engine operating phases. The unique PCV adapter design eliminates the need to permanently cap or plug factory PCV holes. The kit features a high-performance check valve to prevent boost leaks and includes quick connect fittings and 3/8” hose for a straightforward and clean installation. The full kit integrates a BMS double baffle OCC, which mounts conveniently on the strut brace alongside the boost side OCC for easy servicing and a tidy appearance. It also comes with a BOV adapter that provides an additional 1/8" NPT vacuum port. A blow-off valve (BOV) is not required for this kit to function. This system negates the need for separate RB PCV or BMS PCV units. This product may not be suitable for regions where temperatures frequently drop to 32°F (0°C) or below.
