Solution

1. Preparation

Gather necessary tools and safety equipment.
Ensure the vehicle is parked on a flat surface and the engine is cool.
Disconnect the battery to prevent electrical shorts.

2. Oil Change (if low or contaminated)

Sub-steps:
1. Place an oil pan under the oil pan to catch the old oil.
2. Remove the oil drain plug and allow the oil to fully drain.
3. Replace the oil filter using an oil filter wrench.
4. Install a new oil filter and tighten it to the manufacturer's specifications (typically hand-tight plus 1/4 turn).
5. Reinstall the oil drain plug and tighten to specifications (usually around 25 Nm).
6. Refill the engine with the appropriate type and amount of oil (consult owner's manual, typically 0W-20 or 5W-30).

3. Inspect Engine Components

Sub-steps:
1. Remove the valve cover by unscrewing the bolts (torque to the manufacturer's specifications when reinstalling).
2. Inspect the rocker arms and valve lifters for wear or damage.
3. If the timing chain is accessible, check for proper tension and any signs of wear.
4. Reassemble the valve cover after inspection, ensuring a proper seal with a new gasket.

4. Repair or Replace Faulty Components

Sub-steps:
1. If any worn rocker arms or lifters are found, replace them accordingly.
2. If the timing chain is identified as faulty, replace it along with tensioners.
3. For faulty injectors, replace with OEM or quality aftermarket parts.
