OVERVIEW
Factory O-ring for the turbocharger oil return connection
WHT-005-363-A is the Genuine VW/Audi O-ring used at the assigned turbocharger oil outlet or return tube connection on the confirmed applications below.
The return line carries oil away from the turbocharger. Its O-ring seals the original tube connection, while the feed line uses a different seal. Select by full part number and connection rather than color alone.
Technical details
- Complete factory number: WHT-005-363-A.
- Factory specification: factory turbocharger oil return-line O-ring WHT005363A.
- Design: individual green sealing ring for the original tube connection.
- Quantity supplied: one individual O-ring.
The selected genuine catalogs identify this part at the return tube. The neighboring feed-line seal WHT006990A is separate. The listing does not include the oil tube, retaining hardware or turbocharger.
Common reasons to replace
- The oil return connection has been opened and requires a new seal.
- The original ring is cut, flattened or damaged.
- The seal has hardened or no longer seats correctly.
- Diagnosis confirms leakage at this sealed connection.
- The original ring is missing or incorrect.
Inspect the tube, groove and mating bore for damage and contamination. Check the cause of oil leakage before replacing the seal. A new O-ring does not repair a cracked tube, damaged turbocharger or obstructed return passage.

Installation guidance
Follow the vehicle-specific turbocharger oil-line procedure. Let the engine cool, clean the mating surfaces and use a new specified seal. Apply only the lubricant prescribed by the repair procedure and avoid twisting or cutting the ring during tube insertion.
Secure the tube with the specified hardware, check the engine oil level and perform the required leak inspection after service.
