Air Cleaner Hose - Cyclone is a crankcase-ventilation breather hose in the 300 Tdi air intake and engine breather system.

It connects the cyclone oil-vapour separator to the air cleaner assembly, routing crankcase blow-by gases through the separator and back into the intake to be re-burned, while limiting oil carry-over into the air filter.

It is commonly renewed alongside the oil-separator drain hose (LLH500190). Rubber breather hoses harden, crack and swell with age and heat, so inspect and replace as required to maintain correct crankcase ventilation.

Frequently asked questions

What is the cyclone air cleaner hose for?

The cyclone air cleaner hose is a crankcase-ventilation breather hose on the 300 Tdi. It connects the cyclone oil-vapour separator to the air cleaner, routing crankcase blow-by gases through the separator and back into the intake to be re-burned, while limiting oil carry-over into the air filter.

Which Defender does this cyclone breather hose fit?

This cyclone breather hose fits the Defender 300 Tdi (1987-2006) from VIN MA939976. It's part of the engine breather and air intake system on that later 300 Tdi build, so check your VIN falls at or after that break before ordering.

Is the cyclone hose usually replaced with any other part?

The cyclone air cleaner hose is commonly renewed alongside the oil-separator drain hose (LLH500190), as both are age-related rubber breather hoses in the 300 Tdi ventilation system. Doing both together typically saves repeating the job when the second hose perishes soon after.

Why do these breather hoses need replacing?

Rubber breather hoses like this cyclone hose harden, crack and swell with age and engine heat. Once they split or collapse, crankcase ventilation on the 300 Tdi is compromised, which can cause oil leaks and pressure build-up. Inspect and replace as required.
