Solution

1. Preparation

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

2. Identify and Replace Leaking Gasket

Tools Required: Socket set, torque wrench, gasket scraper, clean cloth, sealant (if necessary)
Locate the specific gasket that is leaking (e.g., valve cover gasket).
Remove any components obstructing access to the gasket.
Carefully remove the old gasket using a gasket scraper.
Clean the mating surfaces thoroughly to ensure a good seal.
Apply a thin layer of sealant (if required) and position the new gasket.
Reinstall components and tighten bolts to manufacturer specifications using a torque wrench.

3. Replace Oil Filter (if leaking)

Tools Required: Oil filter wrench, drain pan
Place a drain pan under the oil filter.
Use the oil filter wrench to remove the old oil filter, allowing oil to drain into the pan.
Lubricate the rubber O-ring on the new oil filter with a bit of new oil.
Install the new oil filter by hand, ensuring it is snug but not overtightened.

4. Tighten or Replace Oil Drain Plug

Tools Required: Socket set
Locate the oil drain plug and inspect it for tightness.
If loose, use the appropriate socket to tighten it to manufacturer specifications.
If damaged, replace the drain plug and apply a new washer if necessary.

5. Refill Engine Oil

Tools Required: Funnel, new engine oil (recommended type for Tesla Model Y)
Remove the oil filler cap and use a funnel to add the correct type and amount of oil.
Replace the oil filler cap and ensure it is secure.
