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.
Disconnect the negative terminal of the battery for safety.

2. Fixing Oil Leak from Oil Filter

Remove the Oil Filter:
- Use an oil filter wrench to unscrew the filter.
- Be prepared for oil spillage; have a drain pan ready.
Inspect and Replace:
- Check the rubber O-ring on the filter for damage.
- Apply a thin layer of new engine oil to the new filter’s O-ring before installation.
- Install the new oil filter by hand, tightening it according to manufacturer specifications (usually 3/4 to 1 full turn after the O-ring makes contact).

3. Repairing Oil Pan Leak

Drain Engine Oil:
- Place a drain pan under the oil pan and remove the oil drain plug using a socket wrench.
- Allow the oil to completely drain out.
Remove Oil Pan:
- Remove any bolts securing the oil pan using a socket set.
- Gently tap the oil pan with a rubber mallet if it is stuck, then carefully remove it.
Clean Surfaces:
- Scrape off the old gasket material from both the oil pan and the engine block using a gasket scraper.
- Clean the surfaces with a solvent to remove any residual oil.
Install New Gasket:
- Place a new gasket on the oil pan or apply a suitable gasket maker if recommended.
- Reinstall the oil pan by aligning it properly and tightening the bolts to the manufacturer’s torque specifications.
Refill Engine Oil:
- Reinstall the oil drain plug and refill the engine with the appropriate type and amount of oil.

4. Final Checks

Reconnect the negative battery terminal.
Start the engine and let it idle, checking for any leaks around the repaired areas.
Dispose of the old oil and filter properly.
