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 prevent any electrical issues during repair.

2. Inspect and Replace Gaskets

Inspect Valve Cover Gasket:
- Remove any engine covers if present.
- Check for oil seeping from the valve cover gasket.
Replace Gasket:
- Remove the valve cover bolts using a socket set.
- Carefully lift the valve cover off and remove the old gasket.
- Clean the mating surfaces with a solvent and a clean rag.
- Place a new gasket onto the valve cover and reassemble.

3. Check and Replace Oil Filter

Inspect Oil Filter:
- Locate the oil filter and check for any oil leaks around it.
Replace Oil Filter:
- Use an oil filter wrench to remove the old filter.
- Apply a thin layer of oil to the rubber gasket of the new filter.
- Install the new filter by hand until snug (do not overtighten).

4. Address Oil Pan Issues

Inspect Oil Pan:
- Check the oil pan for leaks or damage.
Replace Oil Pan Gasket if Necessary:
- Drain the engine oil using an oil drain pan.
- Remove the oil pan bolts and gently pry the oil pan away from the engine.
- Clean both surfaces and install a new gasket.
- Reattach the oil pan and refill with new engine oil.
