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 for safety.

2. Addressing Oil Leaks

Tools Required: Socket set, torque wrench, oil catch pan.
Locate the source of the leak (e.g., valve cover gasket, oil filter).
Remove any components blocking access to the leaking area if necessary.
If the valve cover gasket is leaking:
1. Remove the valve cover bolts using the socket set.
2. Carefully lift off the valve cover and remove the old gasket.
3. Clean the mating surfaces with a gasket scraper and solvent.
4. Install a new gasket and reassemble the valve cover, tightening bolts to manufacturer's torque specifications.
If the oil filter is leaking:
1. Remove the old oil filter using an oil filter wrench.
2. Apply a thin layer of new oil to the rubber gasket of the new filter.
3. Install the new filter, hand-tightening it securely.

3. Oil Change

Tools Required: Oil catch pan, funnel, socket set, oil filter wrench.
Drain the old oil:
1. Position the oil catch pan under the oil pan.
2. Remove the oil drain plug using a socket set and allow oil to fully drain.
Replace the oil filter (if not done earlier).
Reinstall the oil drain plug and tighten to the proper torque.
Add new engine oil according to manufacturer specifications using a funnel.
