Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the negative battery terminal for safety.

2. Check and Change Engine Oil

Tools Required: Wrench set, oil filter wrench, oil catch pan.
Remove the oil drain plug and drain the old oil into the catch pan.
Replace the oil filter using the oil filter wrench.
Reinstall the drain plug and refill the engine with fresh oil to the manufacturer's specifications.

3. Adjust Valve Clearance

Tools Required: Feeler gauge, socket set, torque wrench.
Remove the valve cover to access the valve train.
Use the feeler gauge to measure the gap between the rocker arm and the valve stem.
Adjust the gap by loosening the lock nut and turning the adjuster screw to the correct specifications.
Reinstall the valve cover with a new gasket, ensuring proper torque.

4. Inspect Timing Belt/Chain

Tools Required: Socket set, torque wrench.
Remove any components obstructing access to the timing belt/chain, such as the engine cover.
Check for signs of wear or damage on the timing belt/chain.
If necessary, replace the timing belt/chain per the manufacturer's service intervals.
