Diagram ref no 16

Connecting the oil filter bracket and oil thermostat circuit, this hose provides a passage for engine oil within the lubrication and cooling system.

An aftermarket alternative to the original Porsche component, ideal for replacing ageing, damaged or leaking oil lines.

What Does It Do?

The oil hose carries engine oil between components of the oil filter and thermostat assembly.

It forms part of the lubrication circuit, helping maintain oil circulation and supporting correct engine oil temperature management.

Why Is It Important?

A sound oil hose helps maintain a sealed lubrication system and prevents unnecessary oil loss.

A damaged hose may cause:

• Engine oil leaks
• Oil residue around hose connections
• Burning oil smells
• Reduced engine oil level
• Potential engine damage if oil loss is ignored

Why Do Oil Hoses Fail?

Age, heat and exposure to engine oil can gradually deteriorate hose materials.

Common causes include:

• Rubber hardening or cracking
• Corrosion around metal fittings
• Vibration and repeated heat cycles
• Damaged or weakened hose connections
• General deterioration with age

When Should It Be Replaced?

Replace the hose if it shows cracking, swelling, corrosion or signs of oil leakage.

Replacement is also advisable during oil thermostat repairs, oil filter bracket servicing or engine restoration.

Installation Notes

Inspect the hose connections and sealing surfaces before installation.

Fit the replacement without twisting or placing strain on the connections. Use the correct fittings and Porsche tightening specifications.

After installation, check the engine oil level and inspect for leaks with the engine running.
