Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a flat surface and the engine is cool.

2. Oil Change (if low or dirty)

Drain old oil:
- Place a drain pan under the oil pan.
- Remove the oil drain plug using a socket wrench and allow the oil to drain completely.
Replace oil filter:
- Use an oil filter wrench to remove the old oil filter.
- Lubricate the rubber gasket of the new filter with fresh oil and install it.
Refill engine oil:
- Reinstall the drain plug and tighten to the manufacturer's torque specification (typically around 20-25 ft-lbs).
- Fill the engine with the recommended oil type (5W-30 synthetic recommended).
- Start the engine and check for leaks and proper oil pressure.

3. Timing Chain/Belt Inspection

Remove engine covers:
- Use a socket set to remove the bolts securing the engine cover.
Inspect timing components:
- Remove the timing cover if needed to inspect the timing chain/belt for wear.
- Replace any damaged components as necessary.

4. Valvetrain Component Inspection

Remove valve cover:
- Use a socket set to remove the bolts securing the valve cover.
Inspect lifters and pushrods:
- Check for any signs of wear or damage.
- Replace any faulty components.
