Solution

1. Preparation

Gather tools and materials: oil catch pan, socket set, ratchet, torque wrench, new oil filter, new oil (Porsche-approved type), rags, and O-ring.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to ensure safety while working on electrical components.

2. Drain Oil

Place the oil catch pan under the oil pan.
Remove the oil drain plug using the socket set and allow the oil to fully drain into the pan.
Replace the drain plug and tighten to manufacturer specifications (typically around 25 Nm).

3. Replace Oil Filter

Locate the oil filter and remove it using an oil filter wrench.
Before installing the new filter, apply a small amount of new oil to the O-ring of the new filter to ensure a proper seal.
Install the new oil filter and tighten it by hand until snug, then give it an additional 3/4 turn.

4. Inspect and Replace Gaskets (if needed)

If leaks were found in gaskets during diagnostics, remove the affected components (e.g., valve cover).
Replace old gaskets with new ones, ensuring the surfaces are clean and free from debris.
Torque the components back to manufacturer specifications.

5. Refill Engine Oil

Pour the appropriate amount of new oil into the engine through the oil filler cap.
Start the engine and let it idle for a few minutes, checking for leaks around the oil filter and drain plug.

6. Final Inspection

After the engine has run for a few minutes, turn it off and check the oil level with the dipstick.
Add oil if necessary to reach the proper level.
