Frequently asked questions

What is the ERR1729 hose for?
The ERR1729 is the crankcase breather hose for the cyclone oil separator on the 2.5-litre naturally aspirated diesel and 200TDi engines. It carries crankcase blow-by gases from the cyclone separator to the air cleaner while the cyclone strips out the entrained oil.
Why does this breather hose fail, and when should it be replaced?
Breather hoses typically perish, harden, or split with age, heat, and oil exposure. Replace it if it's cracked, soft, or leaking oil mist around the joints. A failed breather hose lets unfiltered fumes escape and upsets crankcase ventilation.
Where does this hose connect?
This hose connects the cyclone oil separator to the air cleaner on the 2.5-litre naturally aspirated diesel and 200TDi engine, routing crankcase fumes back into the intake. It's part of the crankcase breather system, not a coolant or fuel line.
Does this hose fit my vehicle?
This breather hose fits the Land Rover Defender (1987-2006) with the 2.5-litre four-cylinder naturally aspirated diesel or 200TDi engine. Confirm your engine type, as the breather routing differs on later Tdi engines.
