Solution

1. Preparation

Tools Required: Socket set, torque wrench, oil catch pan, rags, engine degreaser, jack and jack stands.
Safely lift the vehicle using jack stands to access the undercarriage.
Ensure the engine is cool before beginning any work.

2. Inspect and Clean

Use engine degreaser to clean the area around the suspected leak. This will help in identifying the source of the leak more clearly.
Allow the degreaser to sit for a few minutes, then rinse with water and dry the area.

3. Replace Gaskets or Seals

Oil Pan Gasket:
1. Drain the engine oil into a catch pan.
2. Remove the oil pan bolts using a socket set.
3. Carefully detach the oil pan and replace the old gasket with a new one, ensuring it is properly aligned.
4. Reinstall the oil pan and torque the bolts to manufacturer specifications (usually around 10-15 ft-lbs).
Valve Cover Gasket:
1. Remove the air intake duct and any components blocking access to the valve cover.
2. Unscrew the valve cover bolts and gently lift off the cover.
3. Remove the old gasket and clean the mating surfaces.
4. Install the new gasket and reattach the valve cover, torquing the bolts to the specified value (typically 7-10 ft-lbs).

4. Test Components

Check the oil filter:
1. Ensure the oil filter is securely tightened; if it’s leaky, replace it with a new filter.
2. Lubricate the rubber gasket on the new filter with a bit of oil before installation.
Inspect the oil pressure sending unit:
1. If leaking, remove the sending unit and replace it with a new one.
2. Ensure it is properly torqued to avoid future leaks.

5. Refill and Finish

Refill the engine with the appropriate oil type and quantity as specified in the owner's manual.
Start the engine and let it run briefly while checking for any signs of leaks.
Recheck the oil level with the dipstick and top off if necessary.
