1. Prep: Clean the oil pan thoroughly, remove excess oil and impurities from the damaged hole area and residual threads.
2. Tap Threads: Screw the piggyback plug into the damaged hole, turn forward a few turns then backward to form tight new threads.
3. Clean Debris: Remove the plug once it bottoms out, fully clean all iron chips around the tapped hole (prevents engine wear from debris entering oil system).
4. Tighten Main Plug: Use a T-socket wrench to torque the main plug to 14ft-lbf (tighten firmly but do not over-tighten to avoid thread damage).
5. Finish: Screw in the small piggyback oil drain plug to complete installation. ⚠️ Critical Note: Keep the large piggyback plug fixed when removing the small plug for oil draining.
