Solution

1. Preparation

Gather tools and materials: oil catch pan, wrench set, new oil filter, new oil, rags, and a funnel.
Ensure the vehicle is on a level surface and the engine is cool.
Disconnect the battery to prevent electrical issues.

2. Address Oil Leaks

Drain Engine Oil:
1. Position the oil catch pan under the oil pan.
2. Remove the drain plug using the appropriate wrench and allow oil to drain completely.
Replace Oil Filter:
1. Use an oil filter wrench to remove the old oil filter.
2. Apply a small amount of new oil to the rubber gasket of the new filter.
3. Install the new oil filter by hand, tightening it according to manufacturer's specifications.
Inspect and Replace Gaskets:
1. Locate the valve cover gasket and inspect for cracks or wear.
2. Remove the valve cover by unscrewing the bolts and gently lifting it off.
3. Clean the mating surfaces with a gasket scraper.
4. Install a new valve cover gasket and reattach the cover, tightening bolts to the specified torque.

3. Refill Engine Oil

Use a funnel to refill the engine with the correct type and amount of oil as specified in the owner’s manual.
Replace the drain plug securely.

4. Check for Additional Issues

Inspect exhaust components for any signs of burning oil and ensure there are no obstructions.
If necessary, repair or replace any damaged components.
