Solution

1. Preparation

Gather necessary tools and materials.
Ensure the vehicle is parked on a level surface and allow the engine to cool.
Disconnect the battery to prevent electrical issues during repair.

2. Locate Leak Source

Use a UV light to identify the location of the leak if not visibly apparent.
Mark the area with a suitable marker for reference.

3. Replace Damaged Seals/Gaskets

Oil Pan Gasket Replacement:
1. Drain the oil completely using an oil catch pan.
2. Remove the bolts securing the oil pan and gently separate it from the engine block.
3. Clean the mating surfaces thoroughly.
4. Install a new oil pan gasket (ensure it is the correct type for your model).
5. Reattach the oil pan, torque bolts to manufacturer specifications (usually around 10-12 Nm).
Valve Cover Gasket Replacement:
1. Remove any components obstructing access to the valve cover (e.g., intake manifold, ignition coils).
2. Detach the valve cover bolts and carefully lift the cover off.
3. Replace the old gasket with a new one, ensuring it fits properly.
4. Reinstall the valve cover and torque bolts to specification (typically 8-10 Nm).

4. Replace Oil Filter and Refill Oil

Remove the old oil filter using an oil filter wrench.
Install a new oil filter, lubricating the gasket with a small amount of fresh oil.
Refill engine oil with the recommended type (Tesla typically uses 0W-20 synthetic oil).

5. Final Checks

Reconnect the battery.
Start the engine and allow it to reach operating temperature.
Inspect the previously marked area for any signs of leakage.
