Oil lines are often overlooked components, yet their failure can lead to significant damage. These lines connect the engine, oil cooler, or timing chain tensioner, functioning reliably for years without drawing attention.
However, if a crack or break develops, substantial amounts of oil may leak—potentially draining the entire oil tank—leaving critical components without proper lubrication. To prevent such failures, it is advisable to replace aging oil hoses or lines at the first signs of wear.
In the context of full restorations, replacing all oil lines or hoses is a common and prudent practice to ensure long-term reliability.

OEMatch Breather Pipes — Fit, Function, Confidence
Breather pipes and crankcase ventilation parts for Porsche models manage oil vapour and internal pressure to protect lubrication and reduce leaks. OEMatch offers a focused selection of hoses, separators and seals suited to Porsche applications, covering routine maintenance and rebuild requirements.
Available Types
- Flexible breather hoses and oil vapour pipes
- Oil separator and catch can assemblies
- Crankcase vent hoses and connecting pipes
- Grommets, seals and mounting fittings
Understanding OEMatch Breather Pipes
OEM (Original Equipment Manufacturer) parts are made by the same company that produced your Porsche’s original breather pipes.
OE (Original Equipment) refers to parts matching original specifications for the breather pipes and may be supplied by alternative manufacturers. Aftermarket parts offer alternative options, sometimes with enhanced features or better value. OEMatch supplies non-OEM breather pipes engineered as direct-fit alternatives to OEM parts, made to original-spec dimensions and tolerances for Porsche models.
Breather pipes route crankcase vapour and blow-by gases away from the engine, helping to separate oil from vapour and return condensate to the sump or collection points. Correct ventilation reduces contamination, prevents pressure build-up and supports stable idling and consistent oil return across Porsche engines.
Benefits Include
- Restores correct crankcase ventilation and pressure control
- Helps reduce oil leaks and visible smoke
- Limits oil contamination and sludge formation
- Supports stable idling and efficient oil return
Why Breather Pipes Wear and Fail
- Heat-related hardening, cracking or brittleness of rubber and plastic hoses
- Oil and carbon build-up causing blockages or restricted flow
- Degraded or collapsed internal liners and collapsed passages
- Loose, hardened or damaged grommets and sealing fittings
The Importance of Replacing with OEMatch Breather Pipes
Keeping breather pipes in good condition prevents oil loss and contamination that can accelerate wear in Porsche engines. Replacing degraded hoses and seals reduces the risk of pressure-related faults and leaks, helping maintain reliable lubrication, consistent idling and longer component life when combined with regular oil and filter care.
Advantages
- Manufactured for oil and heat resistance appropriate to engine conditions
- Produced to original-spec dimensions for consistent performance
- Suitable for air-cooled and water-cooled Porsche engine layouts
