6. Fill the engine with the recommended oil type (check owner’s manual for specifications).

3. Valve Adjustment (if applicable)

Sub-steps:
1. Remove the valve cover by loosening the bolts with a socket wrench.
2. Inspect the valvetrain components for wear or damage.
3. Measure the valve clearance using a feeler gauge and adjust if necessary by loosening the adjustment screws and repositioning them.
4. Reinstall the valve cover with a new gasket, ensuring proper torque specifications are followed.

4. Timing Chain/Belt Inspection

Sub-steps:
1. Remove any components obstructing access to the timing chain/belt (such as the timing cover).
2. Inspect the timing chain/belt for wear, tension, and alignment.
3. If wear is present, replace the timing chain/belt according to manufacturer specifications.
