Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat surface and the engine is cool.
Disconnect the battery for safety.

2. Address Oil Pan Leak

Sub-step 1: Drain the engine oil using a wrench to remove the drain plug. Allow oil to fully drain into a catch pan.
Sub-step 2: Remove the oil pan by unscrewing the bolts with a socket set. Carefully lower the pan to avoid damaging the gasket.
Sub-step 3: Inspect the oil pan for cracks or damage. If damaged, replace with a new oil pan.
Sub-step 4: Clean the mating surface on the engine block and the oil pan with a solvent.
Sub-step 5: Install a new oil pan gasket, then reattach the oil pan and tighten bolts to manufacturer-recommended torque specifications.

3. Replace Valve Cover Gasket

Sub-step 1: Remove any covers or components obstructing access to the valve cover.
Sub-step 2: Unscrew the valve cover bolts using a socket set and gently lift the valve cover.
Sub-step 3: Remove the old gasket and clean the mating surfaces.
Sub-step 4: Place a new valve cover gasket and reattach the valve cover, tightening bolts to manufacturer specifications.

4. Replace Faulty Oil Filter

Sub-step 1: Use an oil filter wrench to remove the old oil filter.
Sub-step 2: Apply a light coat of new engine oil to the rubber gasket of the new oil filter.
Sub-step 3: Install the new oil filter by hand until snug, then tighten according to the manufacturer's specifications.

5. Final Assembly

Sub-step 1: Refill the engine with new oil through the oil filler cap, ensuring the correct oil type is used.
Sub-step 2: Reconnect the battery and start the engine, allowing it to run for a few minutes.
Sub-step 3: Check for leaks around the oil pan, valve cover, and oil filter.
