2. Inspect and Replace Oil

Sub-steps:
1. Remove the oil filler cap and check the oil level.
2. If oil is low or dirty, drain the old oil using an oil drain pan.
3. Replace with manufacturer-recommended oil (5W-30 synthetic oil).
4. Replace the oil filter using an oil filter wrench.

3. Valve Adjustment (if applicable)

Sub-steps:
1. Remove the valve cover by unscrewing the bolts (use a torque wrench set to manufacturer specifications).
2. Inspect the rocker arms and lifters for wear; replace any damaged components.
3. Adjust the valve clearance according to the specifications provided in the service manual.
4. Reinstall the valve cover with a new gasket ensuring proper seals.

4. Timing Chain/Belt Inspection

Sub-steps:
1. Remove any components obstructing access to the timing chain/belt (such as the engine cover).
2. Check for proper tension and alignment of the timing chain/belt; replace if worn or misaligned.
3. Reinstall all components securely.

5. Reassemble and Test

Sub-steps:
1. Reconnect the battery.
2. Start the engine and listen for any remaining noise.
