The breather hose allows crankcase vapours and oil mist to be routed correctly through the engine ventilation system. A properly sealed breather hose helps prevent vacuum leaks, oil vapour escape, and poor engine running caused by damaged or split ventilation hoses.
Functions
• Replaces the engine breather hose
• Supports crankcase ventilation system operation
• Helps route oil vapour and crankcase gases correctly
• Helps prevent vacuum leaks and oil mist escape
• Supports smooth idle and reliable engine performance
• Suitable for engine service, oil leak repair, or restoration work
• OE Match replacement for Porsche 993 breather system maintenance.
Why Replace This Part?
Breather hoses can harden, crack, split, collapse, or become oil-soaked due to age, heat, oil vapour exposure, and engine bay conditions.

When to Replace This Part
• Breather hose is cracked, brittle, split, or leaking
• Oil vapour smell or oil mist residue is present
• Rough idle or vacuum leak symptoms are detected
• Engine breather system service is being carried out
• Oil leak investigation or engine bay restoration is in progress
• Hose has become soft, swollen, collapsed, or loose.
