Solution

1. Preparation

Tools Required: OBD-II scanner, mechanic's stethoscope, socket set, torque wrench, engine oil.
Ensure the vehicle is parked on a level surface, and the engine is cool before starting work.
Disconnect the battery to prevent electrical shorts.

2. Check Engine Oil

Check the oil level using the dipstick.
If low, add the recommended engine oil (Porsche recommends using synthetic oil 0W-40).
If the oil is dirty or contains debris, proceed to drain and replace it.

3. Remove Valve Covers

Tools Required: Socket set.
Remove the bolts securing the valve covers using the socket set.
Carefully lift off the valve covers and inspect the rocker arms and valve lifters for wear or damage.

4. Inspect Timing Chain

Check the timing chain tensioner for proper operation.
If the tensioner is faulty, replace it according to the manufacturer's specifications.
Ensure the timing chain is properly aligned and not excessively worn.

5. Reassemble and Refill

Reinstall the valve covers, ensuring to torque the bolts to the manufacturer's specified torque settings (typically around 10-15 Nm).
Refill the engine with the correct oil if it was drained.
Reconnect the battery and clear any diagnostic codes.
