Solution

1. Preparation

Gather tools and materials needed for repair.
Tools Required: Socket set, torque wrench, oil filter wrench, rags, engine degreaser.
Ensure the vehicle is parked on a level surface and the engine is cool.

2. Replace Valve Cover Gasket

Disconnect the negative battery terminal.
Remove any components obstructing access to the valve cover (e.g., air intake duct).
Unscrew and remove the valve cover bolts using the socket set.
Carefully lift the valve cover off, ensuring no debris falls into the engine.
Remove the old gasket and clean the mating surfaces with a degreaser.
Place the new valve cover gasket onto the valve cover.
Reinstall the valve cover and torque the bolts to the manufacturer's specifications (typically around 7.5 ft-lbs).
Reconnect any components that were removed.

3. Replace Front Main Seal

Remove the crankshaft pulley using the socket set.
Remove the timing cover by unscrewing the bolts and gently prying it away.
Carefully remove the old front main seal using a seal puller or a flat tool.
Install the new front main seal, ensuring it is seated evenly.
Reinstall the timing cover and crankshaft pulley, torquing to specifications.
Refill engine oil if necessary and reconnect the battery terminal.
