my Volkswagen Golf Eighth Generation (2020-present) is leaking oil, what should I inspect

Solution

1. Preparation

• Gather necessary tools and parts.
• Park the vehicle on a level surface and allow the engine to cool.
• Disconnect the battery to prevent any electrical issues.

2. Inspect and Replace Gaskets

• Valve Cover Gasket Replacement:

  • Remove the engine cover if present.
  • Unbolt the valve cover, carefully lifting it to avoid damaging the gasket.
  • Clean the mating surfaces on the engine and valve cover.
  • Install a new valve cover gasket and reassemble the valve cover, tightening bolts to manufacturer’s specifications (typically 10-15 Nm).

• Oil Pan Gasket Replacement:

  • Raise the vehicle using a jack and secure it with jack stands.
  • Drain the engine oil and remove the oil pan bolts.
  • Carefully pry off the oil pan and clean the mating surfaces.
  • Install a new oil pan gasket, ensuring proper alignment, and reattach the oil pan, tightening bolts to manufacturer’s specifications (typically 10-15 Nm).

3. Replace Oil Filter

• Remove the old oil filter using an oil filter wrench.
• Apply a thin layer of oil to the rubber O-ring of the new oil filter.
• Install the new oil filter hand-tight and then tighten it according to the manufacturer's specifications.

4. Refill Engine Oil

• Refill the engine with the appropriate type and amount of oil (check the owner's manual; typically, 5W-30 synthetic oil is recommended).
• Start the engine and let it idle for a few minutes while checking for leaks.

5. Clean Up

• Dispose of old oil and oil filters according to local regulations.
• Clean any oil spills with degreaser.
