Solution

1. Preparation

Gather necessary tools and parts. Ensure the vehicle is on a level surface.
Tools Required: Jack and jack stands, socket set, torque wrench, oil catch pan, rags, OBD-II scanner.
Safety Warnings: Allow the engine to cool completely before starting work. Wear gloves and safety goggles.

2. Addressing Leaks from the Oil Filter

Remove the oil filter using an oil filter wrench.
Inspect the rubber O-ring on the old filter for damage. If it's damaged, replace the filter with a new one.
Clean the mounting surface on the engine block to remove old oil and debris.
Apply a small amount of new engine oil to the O-ring of the new filter.
Install the new filter by hand until snug, then tighten it slightly with the wrench (do not overtighten).

3. Replacing Front Crankshaft Seal

Remove any components obstructing access to the front crankshaft seal (e.g., accessory belts, pulleys).
Use a socket set to remove the crankshaft pulley.
Carefully pry out the old crankshaft seal using a seal puller or a flat-head screwdriver.
Clean the seal bore in the engine with a rag.
Apply a small amount of engine oil to the new seal’s lip.
Press the new seal into place using a seal installation tool or a suitable socket (ensure it is seated evenly).
Reinstall the crankshaft pulley and torque it to the manufacturer’s specifications.

4. Replacing Valve Cover Gasket

Remove any components blocking access to the valve cover (e.g., ignition coils, wiring harness).
Unbolt the valve cover using a socket set and lift it off carefully.
Remove the old valve cover gasket and clean the surfaces of the valve cover and cylinder head.
Place the new gasket onto the valve cover.
Reinstall the valve cover and bolt it down to the manufacturer's torque specifications.
