Solution

1. Preparation

Gather tools and parts required for the repair.
Disconnect the battery to ensure safety while working on electrical components.

2. Identify and Replace Gaskets/Seals

Locate the source of the leak: Based on diagnostic steps, identify whether the leak is from the valve cover gasket, oil pan gasket, or oil seals.
For valve cover gasket:
- Remove any components obstructing access to the valve cover (e.g., air intake ducts).
- Unbolt the valve cover carefully.
- Remove the old gasket and clean the mating surfaces.
- Install a new gasket and reassemble the valve cover, torqueing bolts to manufacturer specifications (typically around 7-9 ft-lbs).
For oil pan gasket:
- Raise the vehicle and secure it on jack stands.
- Drain the engine oil by removing the oil pan drain plug.
- Unbolt the oil pan and carefully remove it.
- Clean the oil pan surface and install a new gasket.
- Reinstall the oil pan, ensuring bolts are torqued to specifications (typically around 12-15 ft-lbs).
For oil seals:
- Remove components as necessary to access the front or rear main seal.
- Use a seal puller to remove the old seals.
- Install new seals, ensuring they are seated properly.

3. Refill Engine Oil

After replacing gaskets or seals, refill the engine with the appropriate oil type (refer to owner’s manual for specifications).
Start the engine and check for leaks around the repaired areas.
