Solution

1. Preparation

Gather necessary tools and materials.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery for safety.

2. Address Oil Leaks

Identify Leak Source
- Clean the engine area with engine degreaser to identify any fresh oil leaks.
- Use a flashlight to inspect hard-to-see areas.
Replace Gaskets and Seals
- If leaks are found at gaskets or seals (e.g., valve cover gasket, oil pan gasket), replace them.
- Remove the old gasket material completely before installing a new gasket.
- Torque bolts to manufacturer's specifications (consult repair manual for exact torque values).

3. Change Engine Oil

Drain Old Oil
- Use an oil drain pan to catch the old oil.
- Remove the oil drain plug with a socket wrench and allow oil to fully drain.
Replace Oil Filter
- Remove the old oil filter with an oil filter wrench.
- Lubricate the rubber gasket on the new oil filter with a bit of new oil and install it.
Fill with New Oil
- Replace the drain plug and tighten it securely.
- Fill the engine with the correct type and amount of oil (check the owner’s manual for specifications).

4. Test and Monitor

Start the engine and let it run for a few minutes.
Check for any signs of leaking and ensure the burnt oil smell has diminished.
