What This Product Does

This hose provides the connecting passage between the separator and plenum, allowing crankcase gases to travel through the ventilation system. It is a connecting hose rather than the oil-separating component itself.

Functions

• Connects the separator outlet with the plenum.
• Provides a passage for crankcase ventilation gases.
• Helps maintain a sealed ventilation connection when correctly fitted.
  
  

Technical Details

• Product reference: 92810772200.
• Brand: OE Match.
• Installation location: between the oil separator and intake plenum.
  
  

Symptoms of Fault

• Visible cracking, brittleness or deterioration of the hose.
• Oily deposits around the hose ends or adjoining connections.
• Uneven idling associated with a ventilation-system air leak.
  
  

These signs warrant inspection but do not establish that this hose is the cause. Check the surrounding ventilation components and connections before replacing parts.

Why Replacement Matters

Renewing a damaged or leaking hose helps restore the intended ventilation path. During maintenance or engine work, inspect adjoining pipework and retaining fittings as well, since deterioration elsewhere can leave a leak unresolved.

FAQs

Does exhaust smoke necessarily indicate a faulty breather hose?
No. Smoke can have several causes, including oil-level or separator problems. Confirm the source rather than replacing the hose on symptoms alone.

What should be checked before fitting?
Compare reference 92810772200, the vehicle details and the original hose connections. Inspect nearby ventilation pipes and fittings for damage.
