Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface.
Allow the engine to cool if recently operated.

2. Addressing Leaks

Valve Cover Gasket Replacement:
- Remove engine cover if applicable.
- Unscrew the valve cover bolts using a socket set (torque specification: 7.5 ft-lbs).
- Gently lift the valve cover and clean the mating surface.
- Replace the old gasket with a new one, ensuring it is seated properly.
- Reinstall the valve cover and tighten bolts to the specified torque.
Oil Filter Replacement:
- Place an oil drain pan under the oil filter.
- Use an oil filter wrench to remove the old filter.
- Apply a thin layer of new oil to the gasket of the new filter.
- Install the new filter by hand until snug, then tighten an additional 3/4 turn.
Oil Pan Repair:
- If leaks are found at the oil pan, drain the oil into a suitable container.
- Remove the oil pan bolts and gently detach the pan.
- Clean the mating surface of the engine and the pan.
- Replace the gasket or sealant as necessary, then reinstall the oil pan, tightening bolts to manufacturer's specifications.

3. Refill Oil

Refill the engine with new oil as per manufacturer specifications (5W-20 for most Corolla models).
Check for proper oil levels using the dipstick.
