A-Premium Crankcase Vent Valve Breather Hose Kit - PCV Replacement

Our review of the A-Premium 5 PCS Crankcase Vent Valve Breather Hose Kit finds it best suited for owners of compatible BMW 6-cylinder models who need a complete PCV service set without sourcing individual pieces. The kit replaces the crankcase valve, breather hoses, return pipe and related connectors in one package, making it ideal for routine maintenance or when a leaking PCV system causes oil smells or rough idle. For many shoppers the biggest reason to buy is convenience: this kit matches original part specifications and arrives ready to install, saving time compared with hunting down several separate parts.

Key Features

• Complete kit: Includes crankcase valve to oil dipstick tube, crankcase breather hose, return pipe, valve cover hose and oil separator so a full PCV service can be performed in one visit.
• OEM-style fit: Designed to match original part specifications so it should align with factory mounting points for a straightforward replacement.
• Wide BMW compatibility: Covers multiple E36, E39, E46, E60, E83 and E85 models with L6 engines, making it useful for garages that work on older BMW 2.5L and 3.0L engines.
• Time savings: Supplying all related hoses and the crankcase pressure regulator in one box reduces parts sourcing and helps complete the job faster.
• Backed warranty: Includes a one-year unlimited-mileage guarantee for added confidence after installation.

Who It's For

This kit is for DIY enthusiasts and independent mechanics who service BMW E36, E39, E46, E60, E83 and E85 series with inline six engines and want a single-purchase solution to replace worn PCV components. It suits owners noticing oil odors, oil in the intake, or crankcase pressure issues who prefer replacing the whole assembly instead of individual pieces.

It is not the best option for someone who needs a single specific OEM hose matched to an unusual submodel or a late-production variant not listed in the fitment. Buyers who require metal fittings or upgraded aftermarket materials for performance builds should look for heavy-duty performance replacements instead.
