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 any electrical issues during repair.

2. Address Oil Leaks

Sub-steps:
1. Remove any components obstructing access to the source of the leak (e.g., engine covers, air intake).
2. Clean the affected area with a degreaser to identify the source of the leak more easily.
3. Replace any worn or damaged gaskets and seals (e.g., valve cover gasket, oil pan gasket).
4. Reassemble any removed components and ensure all fasteners are tightened to manufacturer specifications.

3. Replace Oil Filter (if needed)

Sub-steps:
1. Place an oil catch pan under the oil filter.
2. Remove the old oil filter using an oil filter wrench, allowing any remaining oil to drain into the pan.
3. Apply a thin layer of new engine oil to the rubber O-ring on the new filter.
4. Install the new oil filter by hand until snug, then tighten an additional 3/4 turn.

4. Add Engine Oil

Sub-steps:
1. If low on oil, refill the engine with the correct type and grade of oil specified in the owner's manual.
2. Use a funnel to prevent spills while pouring oil into the engine.
3. Start the engine and allow it to run for a few minutes, then check the oil level again and add more if necessary.

5. Final Check

Sub-steps:
1. Inspect the engine for any new signs of leaking oil after repairs.
2. Ensure there are no visible smoke or burning oil smells while the engine is running.
