OVERVIEW

The BMS Oil Catch Can addresses the oil control problems common on Gen 2 B58-powered BMWs, where blow-by oil coats the intercooler and charge piping and gunks up intake valves and VANOS — an issue that gets worse at higher boost. Built from the ground up for the Gen 2 B58 application, it avoids the shortcomings of other catch cans on the market (hot-side mounting, undersized hoses, poor or overly restrictive baffling, or PCV bypass).

SPECS

100% CNC machined, zero welding; anodized black aluminum; made in the USA and guaranteed for life
Retains factory fully closed-loop PCV operation — no venting to atmosphere
Non-clogging triple-baffle air/oil separation with a free-flow, no-restriction design
Large 16mm+ inlet/outlet exceeding OEM PCV sizing, with no line tapering, to prevent crankcase pressure buildup

Fluid capacity: up to 5.5 fl oz (162.6 mL)
Optional transparent can base available (not recommended for regions that regularly see temps at or below 32°F/0°C)
Optional add-on: BMS Oil Filler Cap Connection Kit, which adds a second dedicated PCV exit point (valve cover breather) for increased vapor capture
