Solution

1. Preparation

Tools Required: Socket set, torque wrench, mechanic’s stethoscope, OBD-II scanner, oil filter wrench.
Safety Warnings: Ensure the engine is cool before starting any work to prevent burns.

2. Change Engine Oil and Filter

Sub-steps:
1. Raise the vehicle with jack stands and secure it.
2. Remove the engine oil drain plug with a socket and let the oil drain completely into a pan.
3. Replace the oil filter using an oil filter wrench.
4. Install a new drain plug with proper torque specifications (usually around 20 lb-ft).
5. Fill the engine with the manufacturer-recommended oil type and amount (check the owner’s manual).

3. Adjust Valve Clearance (if applicable)

Sub-steps:
1. Remove the valve cover by unscrewing it and disconnecting any attached components.
2. Use a feeler gauge to check the valve clearance for each valve.
3. Adjust the clearance using appropriate shims or adjusting screws, following manufacturer specifications.
4. Reinstall the valve cover with a new gasket to prevent leaks.

4. Inspect and Replace Lifters (if necessary)

Sub-steps:
1. If lifters are suspected, remove the rocker arms and valve cover.
2. Inspect each lifter for wear or damage.
3. Replace any faulty lifters with new ones, ensuring they are properly seated.
4. Reassemble components in the reverse order, ensuring all fasteners are torqued to specifications.
