Solution

1. Preparation

• Gather tools and materials needed for the repair.
• Disconnect the negative battery terminal to prevent electrical shorts.
• Allow the engine to cool before beginning work.

2. Inspect and Change Engine Oil

• Sub-steps:
  1. Remove the oil drain plug using a socket set and drain the old oil into a pan.
  2. Replace the oil filter using an oil filter wrench.
  3. Install the drain plug and torque it to the manufacturer’s specification (usually 27 ft-lbs).
  4. Refill the engine with the appropriate type and amount of oil (typically 0W-20 for Toyota engines).
  5. Start the engine and allow it to run for a few minutes while checking for leaks.

3. Check and Replace VVT Oil Control Valve (if necessary)

• Sub-steps:
  1. Locate the VVT oil control valve (usually on the cylinder head).
  2. Disconnect the electrical connector from the valve.
  3. Remove the mounting bolts and carefully take out the valve.
  4. Install the new VVT oil control valve, ensuring it is properly seated.
  5. Reconnect the electrical connector and torque the mounting bolts to specification.

4. Inspect and Replace Timing Chain/Belt (if necessary)

• Sub-steps:
  1. Remove any components obstructing access to the timing cover (e.g., intake manifold).
  2. Remove the timing cover bolts and gently pry off the cover.
  3. Inspect the timing chain/belt for wear or damage; replace if necessary.
  4. Align the timing marks according to the service manual and install the new chain/belt.
