Solution

1. Preparation

Tools Required: OBD-II scanner, mechanic's stethoscope, socket set, torque wrench, compression tester.
Ensure the engine is cool before starting work. Disconnect the battery to avoid electrical hazards.

2. Change Engine Oil

Drain Old Oil: Remove the oil drain plug and allow the old oil to fully drain into a suitable container.
Replace Oil Filter: Use an oil filter wrench to remove the old filter. Lubricate the rubber gasket of the new filter with fresh oil, then install it securely.
Add New Oil: Reinstall the drain plug and fill the engine with the manufacturer-recommended oil type and quantity.
Check for Leaks: Start the engine and monitor for any oil leaks around the filter and drain plug.

3. Tighten Loose Components

Inspect Fasteners: Use a socket set to check and tighten all bolts and fasteners on the engine, particularly those related to the exhaust manifold and heat shields.
Re-check Accessory Mounts: Ensure all accessory mounts (like the alternator and power steering pump) are secure.

4. Inspect and Adjust Valve Train

Remove Valve Cover: Use a socket set to carefully remove the valve cover and inspect the rocker arms and pushrods for damage or excessive wear.
Adjust Valve Clearance: If applicable, adjust the valve clearance according to the manufacturer specifications.
Reinstall Valve Cover: Clean the mating surfaces and apply a new gasket, then reinstall the valve cover with the correct torque specifications.

5. Perform Compression Test (if needed)

Remove Spark Plugs: Disconnect the ignition coil or spark plug wires and use a socket set to remove the spark plugs.
Insert Compression Tester: Insert the compression tester into the first cylinder and crank the engine for several revolutions.
Record Results: Repeat for all cylinders and compare readings to manufacturer specifications. Address any low compression issues if found.
