Mishimoto Crankcase Catch Tank Kit for BMW E82 E9x E89 N54

Stop oily vapour recirculating through your turbocharged straight-six. This Mishimoto compact catch tank kit is the proven PCV upgrade for BMW E chassis N54 platforms, helping curb valve coking, keeping the charge system cleaner and supporting consistent performance on daily drivers and remapped builds alike. It is a neat, model-specific solution that bolts in cleanly with hoses and a bracket designed around the factory breather layout.

We run this set-up on our own N54 projects and customer cars with excellent results. Expect a tidier intake tract, reduced residue in the intercooler and steadier combustion quality under load.

Real-world benefits

• Helps reduce intake valve deposits typical of direct injection by separating oil mist from crankcase fumes before they re-enter the intake
• Lowers the amount of oil film reaching charge pipes and the intercooler core, supporting repeatable performance
• Assists octane stability on spirited drives and tuned cars by limiting oil contamination of the incoming air
• Supports VANOS health by limiting oil carryover through the breather circuit
• Tidy, OEM-style installation that is fully serviceable for long-term ownership

Technical highlights

• Compact 2-port baffled can with an application-specific CNC-machined lid sized to suit the factory breather lines
• Internal baffle and air diverter to improve separation efficiency
• 50 micron bronze filter to capture fine oil particles from blow-by gases
• Billet 6061 aluminium construction with a sealed, serviceable design
• Vehicle-specific mounting bracket places the unit in an accessible location
• Pre-formed hoses for a clean, factory-like appearance with no trimming of the engine cover
• Two plastic 3/4 inch barbed fittings included
• Backed by the Mishimoto Lifetime Warranty
