Solution

1. Preparation

Gather required tools and parts.
Disconnect the battery to ensure safety during work.

2. Check and Change Engine Oil

Sub-steps:
- Locate the oil drain plug and place a drain pan underneath.
- Remove the drain plug and allow the old oil to completely drain.
- Replace the drain plug and tighten to the manufacturer’s torque specification.
- Remove the old oil filter using an oil filter wrench.
- Install a new oil filter, applying a thin layer of new oil to the gasket before installing.
- Refill the engine with the correct type and amount of engine oil as specified in the owner’s manual.

3. Inspect and Adjust Valvetrain Components

Sub-steps:
- Remove the engine cover to access the valvetrain.
- Inspect the rocker arms, pushrods, and springs for signs of wear or damage.
- Adjust the valve clearance if necessary, following the specifications in the repair manual.
- Reassemble the engine cover securely.

4. Repair or Replace Components

If the noise persists after oil change and valve adjustments:
- Identify specific components causing the noise (e.g., lifters, timing chain).
- Replace faulty components following manufacturer guidelines for installation and torque specifications.
