2. Change Engine Oil

Sub-steps:
1. Remove the oil drain plug and drain the old oil into a suitable container.
2. Replace the oil filter using an appropriate oil filter wrench.
3. Install a new oil filter, ensuring the rubber gasket is lubricated with fresh oil.
4. Reinstall the oil drain plug and torque to manufacturer specifications (typically around 30 lb-ft).
5. Fill the engine with the appropriate type and amount of engine oil (5W-20 for most models).

3. Inspect and Replace Valvetrain Components (if necessary)

Sub-steps:
1. Remove the engine cover by unscrewing the retaining bolts.
2. Inspect the rocker arms and valves for wear or damage. Replace any worn components.
3. Reassemble the rocker arms and torque to manufacturer specifications.
4. Replace the engine cover and secure it with the bolts.

4. Repair Exhaust Leaks (if found)

Sub-steps:
1. Remove any components obstructing access to the exhaust manifold, if necessary.
2. Replace any damaged gaskets or hardware on the exhaust manifold.
3. Tighten all bolts to the specified torque settings.
4. Reassemble any removed components.

5. Replace Timing Chain/Belt Tensioner (if needed)

Sub-steps:
1. Remove the timing cover by unscrewing the retaining bolts.
2. Inspect the timing chain/belt and tensioner for wear.
3. Replace the tensioner with a new one, ensuring it is properly aligned.
4. Reinstall the timing cover and secure it with bolts.
