how to check for oil leaks in my Volkswagen Golf MK7 (2015-2019)

Solution

1. Preparation

• Gather necessary tools and parts.
• Ensure the vehicle is parked on a level surface and the engine is cool.
• Disconnect the battery to ensure safety.

2. Clean the Area

• Clean the engine and surrounding areas using a degreaser to remove old oil residues.
• Rinse and allow to dry completely.

3. Inspect and Replace Gaskets and Seals

• Inspect: Visually check the valve cover gasket, oil pan gasket, and rear main seal.
• Replace:
  • Remove any components blocking access to the gasket or seal.
  • Unscrew the old gasket or seal and clean the mating surface.
  • Apply a thin layer of gasket maker if required.
  • Install the new gasket or seal, ensuring proper alignment.
  • Torque bolts to the manufacturer’s specifications (consult service manual for specific torque values).

4. Check and Tighten Oil Filter and Drain Plug

• Check: Ensure the oil filter is properly seated and not leaking.
• Tighten: Use an oil filter wrench to tighten the oil filter if it is loose.
• Drain Plug: Use a socket set to check the tightness of the drain plug, ensuring it is secure but not overtightened.

5. Refill Oil and Test

• Refill engine oil to the specified level using the correct oil type as per the manufacturer’s specifications.
• Start the engine and let it idle for a few minutes while checking for leaks.
