my Skoda Octavia NFL (2020-Present) has an oil leak under the engine, what should I do?

Solution

1. Preparation

• Gather tools and parts required for the repair.
• Park the vehicle on a level surface and ensure the engine is cool.
• Disconnect the battery for safety.

2. Identify the Source of the Leak

• Inspect the oil filter for correct installation and tightness. If loose, tighten it to manufacturer specifications.
• Check the oil drain plug. If it is leaking, tighten it or replace the washer.
• Examine the valve cover gasket. If oil is leaking from here, it may need to be replaced.

3. Replace the Oil Filter (if necessary)

• Tools Required: Oil filter wrench, oil catch pan.
• Remove the old oil filter using the oil filter wrench.
• Apply a thin layer of new oil to the rubber gasket of the new filter.
• Install the new oil filter and tighten according to specifications (typically hand-tight plus a quarter turn).

4. Replace the Oil Drain Plug Washer (if necessary)

• Tools Required: Socket set.
• Use a socket to remove the oil drain plug.
• Replace the old washer with a new one.
• Reinstall the drain plug and tighten to manufacturer specifications (typically 25 Nm).

5. Replace Valve Cover Gasket (if necessary)

• Tools Required: Socket set, gasket scraper, torque wrench.
• Remove any components obstructing access to the valve cover.
• Unbolt the valve cover using a socket set.
• Carefully remove the old gasket and clean the surface with a gasket scraper.
• Install the new gasket and reassemble the valve cover, tightening bolts to manufacturer specifications (typically in a crisscross pattern to 10 Nm).
