Solution

1. Preparation

• Gather tools and parts required for the repair.

2. Disconnect the electrical connector from the VVT oil control valve.
3. Remove the mounting bolts using a socket set.
4. Carefully pull the valve out of its housing.

2. Replace the oil filter using an oil filter wrench.
3. Install a new oil filter and tighten it to manufacturer specifications.
4. Reinstall the oil drain plug and torque it to the specified value (typically 25-30 ft-lbs).
5. Refill the engine with the manufacturer-recommended oil type (usually 0W-20 for Corolla) and check the level.

4. Inspect Timing Chain/Belt

1. Remove any components obstructing access to the timing chain/belt cover.
2. Visually inspect the timing chain/belt for wear and alignment.
