Solution

1. Preparation

Ensure the vehicle is parked on a level surface and the engine is cool.
Gather all necessary tools and parts.
Disconnect the battery to prevent any electrical issues.

2. Inspect and Replace Gaskets/Seals

Valve Cover Gasket Replacement
- Remove the engine cover if applicable.
- Unbolt the valve cover carefully using a socket set.
- Remove the old gasket, clean the mating surfaces with a scraper, and install the new gasket.
- Reinstall the valve cover and torque to manufacturer specifications (typically around 10-15 Nm).
Oil Filter Replacement
- Using an oil filter wrench, remove the old oil filter.
- Apply a small amount of new oil to the rubber O-ring of the new filter.
- Install the new oil filter, hand-tightening it securely.
Oil Pan Gasket Replacement (if necessary)
- Drain the engine oil using an oil drain pan.
- Remove the oil pan by unbolting it.
- Clean the oil pan and engine block surfaces thoroughly.
- Install a new oil pan gasket and reattach the oil pan, torquing bolts to manufacturer specifications (typically around 8-10 Nm).

3. Refill Engine Oil

Refill the engine with the correct type and amount of oil as specified in the owner's manual (typically 5W-30 or 0W-40 synthetic oil).
Check the oil level with the dipstick to ensure it is at the correct level.
