Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a level surface and securely supported with jack stands.
Allow the engine to cool completely.

2. Identify and Replace Leaking Gaskets/Seals

Remove Engine Covers (if applicable)
- Use a socket set to remove bolts securing the engine covers.
- Carefully lift off the covers to expose the engine components.
Inspect and Remove Faulty Gaskets/Seals
- Locate the oil filter, oil pan, and any valve cover seals.
- If there’s damage, use a wrench to remove the oil filter and drain plug.
- Use a scraper to remove old gasket material from the mating surfaces.
Install New Gaskets/Seals
- Apply gasket maker as per manufacturer specifications if needed.
- Position and torque new gaskets/seals to the specified torque values (refer to service manual).
- Reinstall the oil filter and drain plug, ensuring they are tight.

3. Clean Up

Use an engine degreaser to clean any residual oil from the engine compartment.
Dispose of any waste oil and old gaskets/seals according to local regulations.

4. Refill Engine Oil

Use the appropriate oil type specified in the owner's manual.
Refill to the correct oil level using the dipstick to check.
