Solution

1. Preparation

Gather tools and materials: socket set, torque wrench, engine degreaser, rags, replacement gaskets or seals as necessary.
Ensure the vehicle is parked on a level surface and the engine is cool.

2. Clean the Engine

Use engine degreaser to clean the front of the engine.
Rinse with water and allow to dry, making it easier to spot the source of the leak.

3. Replace Oil Filter (if leaking)

Remove the old oil filter using an oil filter wrench.
Lubricate the rubber gasket on the new oil filter with fresh oil.
Install the new oil filter and tighten it to manufacturer specifications (usually hand-tight plus a quarter turn).

4. Replace Gaskets/Seals

For Valve Cover Gasket:

Remove the valve cover by unscrewing the retaining bolts using a socket set.
Carefully lift off the valve cover and scrape off the old gasket material.
Place the new gasket onto the valve cover and re-install it, tightening the bolts to the specified torque (usually around 7-10 ft-lbs).

For Front Crankshaft Seal:

Remove any components obstructing access to the crankshaft seal.
Using a seal puller, remove the old crankshaft seal.
Install the new crankshaft seal, ensuring it is seated evenly and flush.

5. Refill Oil

Check the oil level and refill with the recommended oil type if low.
Start the engine and let it run for a few minutes while observing for any new leaks.
