  • Used at the oil-filter-cap positions in the applicable D8 oil module

📋 Kit Contents

  • 1 × oil-filter-cap O-ring kit - 23958438
  • Earlier single O-ring reference replaced by the kit - 21600674

🔌 Function

Seals the oil-filter cap to the oil-module housing so pressurised engine oil remains contained and unfiltered oil cannot bypass the intended joint.

⚠️ Common Signs of Failure

  • Oil seepage around the filter cap
  • A flattened, cut, twisted or hardened O-ring
  • Oil residue returning shortly after filter service
  • Loss of oil with no other external leak identified
  • Poor cap sealing after the correct cap torque has been applied

🛠️ Service Notes

  • Replaces the earlier single O-ring 21600674 - confirm which number your parts list calls for before ordering
  • Renew every time the D8 oil-module filter cap is removed; it is not intended for reuse
  • Confirm your oil-module version before ordering, since not every D8 filter-cap housing shares this joint
