Olieafscheiderslang – Carterontluchting is de rubberen afvoerslang die afgescheiden olie van de olieafscheider van de carterontluchting terugvoert naar het motorcarter.

De slang maakt deel uit van het carterventilatiesysteem. Terwijl blow-by gassen door de olieafscheider van de carterontluchting stromen, worden oliedruppels opgevangen en verzameld; deze slang leidt die olie terug naar het carter in plaats van deze in de ontluchtingsconstructie te laten ophopen of in het inlaatspruitstuk te laten terechtkomen. Een correcte conditie van deze slang is belangrijk voor het handhaven van effectieve carterventilatie.

Frequently asked questions

What does the oil separator drain hose do?

The oil separator drain hose returns separated oil from the crankcase breather oil separator back to the engine sump. It's part of the crankcase ventilation system, channelling captured oil droplets to the sump instead of letting them reach the intake. It fits the Discovery 1 and Range Rover Classic 2.5L TDi and 300TDi.

Why does the breather drain hose need replacing?

The breather drain hose typically perishes, hardens, or splits with age and exposure to heat and oil, which can let it leak or collapse and upset crankcase ventilation. Replace it if the rubber is cracked, swollen, or soft, as a failed hose can cause oil misting or crankcase pressure build-up.

How do I confirm this hose fits my vehicle?

On the Discovery 1 this hose fits the 2.5L TDi (Gem EGR) and 300TDi up to VIN MA081992; on the Range Rover Classic it fits the 2.5L TDi from VIN JA610294. Check your VIN against these breaks to confirm the correct breather setup before ordering.
