🔌 Function

Guides the dipstick down to the correct depth in the sump and seals the tube's connection, so the reading is repeatable and no oil escapes round the tube.

⚠️ Common Signs of Failure

• Oil weeping or misting round the base of the dipstick tube
• Dipstick reading inconsistent between checks, or the stick not seating fully
• Dipstick hard to withdraw or reinsert, catching part way down
• Tube found bent, corroded or loose in its seat on inspection

🛠️ Service Notes

• Renew the O-ring at the tube connection whenever the tube is pulled - it is the usual source of the leak, not the tube itself
• Check the dipstick slides the full depth freely before declaring the job done; a bent tube gives a false low reading and invites overfilling
