Solution

1. Preparation

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

2. Address Oil Filter Leak

Remove the Oil Filter
- Use an oil filter wrench to remove the old oil filter.
- Ensure the old gasket comes off with the filter.
Install the New Oil Filter
- Apply a thin layer of fresh oil to the new filter gasket.
- Install the new oil filter by hand until snug, then tighten an additional 3/4 turn.

3. Repair Oil Pan Gasket

Drain Engine Oil
- Place a drain pan under the oil pan.
- Remove the oil drain plug and allow the oil to fully drain.
Remove the Oil Pan
- Unscrew the bolts securing the oil pan using a socket set.
- Carefully pry the oil pan loose; avoid damaging the mating surfaces.
Replace the Gasket
- Clean the oil pan and engine mating surfaces thoroughly.
- Place a new oil pan gasket on the cleaned surface.
Reinstall the Oil Pan
- Align the oil pan over the gasket and secure it with bolts.
- Torque the bolts to the manufacturer’s specifications (usually around 10-12 ft-lbs).
Refill Engine Oil
- Replace the oil drain plug.
- Refill the engine with the appropriate type and amount of oil as specified in the owner’s manual.

4. Inspect and Replace Seals (if necessary)

Remove Harmful Components
- If either crankshaft seal is leaking, remove the necessary components to access the seal (may include the timing belt or cover).
Replace Crankshaft Seal
- Carefully pry out the old seal using a seal puller.
- Install the new seal, ensuring it is seated evenly.
Reassemble Components
- Reinstall any components that were removed during the seal replacement.
