Replace the oil filter with a new one.
Refill the engine with fresh oil that meets the manufacturer’s specifications.

3. Inspect and Replace VVT Oil Control Valve

Tools Required: Socket set, wrench set, torque wrench.
Locate the VVT oil control valve (usually near the camshaft).
Remove the electrical connector from the valve.
Unbolt and take out the old VVT oil control valve.
Install the new VVT oil control valve, making sure to torque the bolts to the manufacturer's specifications.

4. Check and Adjust Timing Chain/Belt

Tools Required: Timing tool set, torque wrench, socket set.
Remove any necessary engine covers to access the timing chain/belt.
Verify alignment of the timing marks according to the manufacturer's specifications.
If misaligned, adjust the timing chain/belt as needed.
