Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Change Engine Oil and Filter

Sub-steps:
1. Remove the oil drain plug using a socket set and allow old oil to drain into a suitable container.
2. Replace the oil filter using an oil filter wrench; lubricate the new filter's rubber seal with fresh oil before installation.
3. Reinstall the oil drain plug and torque to manufacturer's specification (generally around 25 Nm).
4. Fill the engine with the appropriate type and amount of oil (e.g., 5W-30 synthetic oil).

3. Inspect and Replace Hydraulic Lifters (if necessary)

Sub-steps:
1. Remove the engine cover to access the cylinder head.
2. Identify and remove any components obstructing access to the lifters (e.g., intake manifold).
3. Carefully remove the old hydraulic lifters using a specialized puller.
4. Install new hydraulic lifters, ensuring they are correctly seated.
5. Reassemble all components in the reverse order, ensuring proper torque settings.

4. Inspect Timing Chain/Belt (if applicable)

Sub-steps:
1. Remove any components necessary to access the timing chain/belt (e.g., front cover).
2. Inspect the timing chain/belt for wear, looseness, or damage.
3. If necessary, replace the timing chain/belt and tensioner according to the manufacturer’s specifications.
4. Reassemble all removed components, ensuring correct torque settings.
