Information
Breather hose, Crankcase to intake manifold.
This OE Match breather hose is a replacement crankcase ventilation hose used on Porsche 955 Cayenne S models. It connects the crankcase breather system to the intake manifold, helping route crankcase vapours back into the engine intake system.
Fits:
Porsche 955 Cayenne S 4.5L 2003 - 2006
Diagram ref no 5
The breather hose forms part of the engine crankcase ventilation system. It allows oil vapour and blow-by gases from the crankcase to be drawn into the intake manifold, where they can be burned through the combustion process. This helps reduce pressure inside the crankcase and supports cleaner, more efficient engine operation.
This hose fits in the engine bay, connecting the crankcase ventilation system to the intake manifold. It is part of the breather / PCV system and is positioned around the upper engine intake area, depending on engine layout.
Functions
• Connects the crankcase breather system to the intake manifold
• Helps route crankcase vapours back into the engine intake
• Supports correct crankcase pressure regulation
• Helps reduce oil vapour build-up inside the engine
• Assists emissions control by recirculating blow-by gases
• Helps maintain stable idle and smooth engine running
• OE Match replacement for cracked, brittle, or leaking original hoses
Why Replace This Part?
Breather hoses are exposed to heat, oil vapour, vacuum pressure, and age-related hardening. Over time, the hose can crack, split, collapse, soften, or leak, which may cause vacuum leaks, rough idle, poor running, oil mist around the engine, or crankcase ventilation faults. Replacing a worn breather hose helps restore correct ventilation and prevents unmetered air from entering the intake system.
When to replace:
• The hose is cracked, brittle, split, collapsed, or oil-soaked
• There is a vacuum leak or hissing noise near the intake manifold
• The engine has rough idle, hesitation, or poor running
• Oil vapour, residue, or mist is visible around the breather connection
• Crankcase ventilation or emissions-related faults are present
• The intake manifold or breather system is being serviced
• As preventative maintenance on ageing original breather pipework
