Solution

1. Preparation

Ensure Safety: Park the vehicle on a level surface and engage the parking brake.
Gather Tools:
- Oil catch pan
- Socket set
- Torque wrench
- Clean rags
- Engine degreaser (if necessary)

2. Addressing the Oil Filter

Remove the Oil Filter:
- Use the socket set to loosen and remove the filter.
- Allow any remaining oil to drain into the catch pan.
Install New Oil Filter:
- Apply a small amount of new oil to the rubber seal of the new filter.
- Thread the new filter by hand until snug, then tighten according to the manufacturer's specifications (usually hand-tight plus a quarter turn).

3. Replacing Gaskets

Remove Affected Components (if necessary):
- Remove the components obstructing access to the leaking gaskets, such as the valve cover or oil pan.
Clean the Surface:
- Use a clean rag and engine degreaser to remove old gasket material and oil residue from mating surfaces.
Install New Gaskets:
- Place new gaskets onto the cleaned surfaces, ensuring correct alignment.
- Reinstall the removed components, tightening bolts to the manufacturer's torque specifications.

4. Test for Leaks

Refill Engine Oil: Add the appropriate amount and type of new oil to the engine.
Start the Engine: Allow the engine to run for a few minutes while checking for leaks around the repaired areas.
Recheck Oil Level: After the engine has run, check the oil level and top up if necessary.
