Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a level surface and the engine is cool.
Wear safety gloves and goggles.

2. Locate the Source of the Leak

Use a flashlight to inspect under the vehicle and identify the leaking area.
Clean the suspected area with a degreaser to ensure a clear view of the leak source.

3. Replace Gaskets or Seals

Oil Filter:
- Remove the old oil filter using an oil filter wrench.
- Apply a thin layer of new oil on the rubber gasket of the new filter.
- Install the new oil filter, tightening it to hand-tight plus a quarter turn.
Valve Cover Gasket:
- Remove the valve cover bolts using a socket set.
- Lift the valve cover off and remove the old gasket.
- Clean the mating surfaces with a gasket scraper.
- Install the new gasket, ensuring it seats properly, and reinstall the valve cover.
Oil Pan Gasket:
- Drain the engine oil using an oil catch pan.
- Remove the oil pan bolts and gently pry the oil pan off.
- Remove the old gasket material from the oil pan and engine block.
- Install a new gasket and reattach the oil pan, torquing bolts to the manufacturer’s specifications (typically 7-9 ft-lbs).

4. Refill Engine Oil

Refill the engine with the appropriate type and amount of oil (typically 5W-20 for the Camry).
Start the engine and run it for a few minutes, checking for leaks around the replaced components.
