Solution

1. Preparation

Tools Required: Socket set, torque wrench, oil catch pan, rags, UV light (if using dye).
Park the vehicle on a flat surface and allow the engine to cool down. Disconnect the battery for safety.

2. Identify and Remove Faulty Components

Sub-steps:
1. Remove Engine Covers: If necessary, remove any engine covers to access the leaking components.
2. Drain Oil: Use an oil catch pan to drain the oil from the engine (if needed for repairs).

3. Replace Gaskets and Seals

Sub-steps:
1. Remove Old Gaskets: Carefully remove the old gaskets or seals from the oil pan, valve covers, or oil filter using a scraper.
2. Clean Surfaces: Thoroughly clean the mating surfaces with solvent to ensure a proper seal.
3. Install New Gaskets: Place new gaskets or seals in position, ensuring they are aligned correctly.

4. Reassemble Components

Sub-steps:
1. Reattach Engine Covers: Replace any engine covers that were removed.
2. Reinstall Oil Filter: If the oil filter was removed, install a new oil filter, ensuring it is snug but not overtightened.
3. Refill Engine Oil: Add new oil to the engine, ensuring it meets Tesla’s specifications.

5. Final Checks

Sub-steps:
1. Reconnect Battery: Reconnect the battery terminals.
2. Start Engine: Start the engine and let it run for a few minutes. Check for any signs of leaks around repaired areas.
3. Check Oil Level: After running, check the oil level again and top off if necessary.
