Solution

1. Preparation

Tools Required: OBD-II scanner, mechanic's stethoscope, socket set, torque wrench, oil filter wrench.
Ensure the vehicle is on a level surface and the engine is cool.
Disconnect the battery to prevent any electrical issues during the repair process.

2. Change Engine Oil and Filter

Lift the vehicle using a jack and secure with jack stands.
Remove the oil drain plug and let the old oil drain completely into a suitable container.
Replace the oil filter using an oil filter wrench.
Install a new oil filter, ensuring the rubber O-ring is lubricated with new oil.
Reinstall the oil drain plug and torque to manufacturer specifications.
Refill the engine with the recommended type and amount of oil.

3. Inspect and Adjust Valve Lash

Remove the valve cover by loosening the bolts with a socket set.
Inspect the condition of the valve cover gasket and replace if necessary.
Use a feeler gauge to measure the valve lash and adjust it as needed according to the specifications in the service manual.
Reinstall the valve cover, ensuring a proper seal, and torque bolts to specifications.

4. Inspect Timing Chain/Belt

If the ticking persists, remove any necessary components to access the timing chain/belt cover.
Inspect the timing chain/belt for wear, tension, and alignment.
Replace the timing chain/belt and tensioner if any signs of wear or damage are present.
Reassemble all components and ensure everything is torqued to specifications.
