⚙️ Key Features

• Oil-vapour-resistant construction
• Correct D3 crankcase-ventilation routing
• Replaces earlier hose assembly 21394438
• Connects the oil trap and ventilation components
• Factory-specified hose shape and end connections

🔌 Function

The hose carries crankcase vapour and separated oil between the engine and oil-trap assembly.

⚠️ Common Signs of Failure

• Oil mist in the engine compartment
• Cracked or hardened hose
• Increased crankcase pressure
• Hose restriction
• Excessive oil residue around connections

🛠️ Service Notes

• Fit the assembly along its original run so the moulded bends and fixed ends sit naturally; forcing a hose to twist or bend tightly to reach it kinks the wall and shortens its life
• Push each end fully home over the stub so the clip lands behind the bead or in its groove, and fit new clips rather than reusing tired or distorted ones
• Tighten clips evenly and only enough to seal — over-tightening cuts into the hose wall and starts the next leak
• Support the assembly with its original clips and stand-offs, clear of the exhaust, belts and sharp edges, and check nothing rubs when the engine moves on its mounts
• Bring the engine up to temperature, then recheck the joints and clip tightness once the hose has been hot and pressurised
