Symptoms of Fault

Why Replacement Matters

A leaking or damaged pipe can allow oil to escape from the lubrication system. Replacing the affected component addresses the identified fault rather than leaving deteriorated pipework in service. Check adjacent connections, seals and supporting hardware during the repair, particularly where older pipework has been disturbed.

FAQs

Does oil around a union mean the pipe needs replacing?
Not necessarily. Inspect the connection and sealing components as well as the pipe itself before deciding which parts require renewal.

Will this suit every 911 S?
No. Pipe arrangements differ between S models, so compare the existing installation and confirm the relevant engine application.

Check fitment for your specific vehicle (model, year, engine) before ordering.
