Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to prevent electrical issues.

2. Addressing Oil Filter and Drain Plug Leaks

Tools Required: Oil filter wrench, socket set, oil catch pan
Sub-steps:
1. Place the oil catch pan under the oil drain plug.
2. Remove the oil drain plug and allow the old oil to drain completely.
3. Replace the drain plug and torque to 25 Nm (18 lb-ft).
4. Remove the oil filter using the oil filter wrench.
5. Apply a thin layer of new oil to the rubber gasket of the new oil filter.
6. Install the new oil filter and tighten by hand until snug.

Tools Required: Socket set, torque wrench, gasket scraper
Sub-steps:
1. Remove any engine covers obstructing access to the valve cover.
2. Disconnect any electrical connectors as necessary.
3. Remove the valve cover bolts using a socket wrench and lift the valve cover off.
4. Clean the mating surfaces with a gasket scraper.
5. Install the new valve cover gasket and position the valve cover back onto the engine.
6. Torque the valve cover bolts to 10 Nm (7.4 lb-ft) in a crisscross pattern.

4. Inspecting and Replacing Seals

Tools Required: Seal puller, socket set, torque wrench
Sub-steps:
1. Depending on the location of the leak, access the front or rear crankshaft seal.
2. Use a seal puller to remove the old seal.
3. Clean the area and install the new seal, ensuring it is seated evenly.
4. Reassemble any components that were removed to access the seals.
