Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a flat surface and the engine is cool.
Disconnect the battery to ensure safety during repairs.

2. Addressing the Oil Filter

Tools Required: Wrench, oil filter wrench, oil catch pan
Remove the old oil filter using the oil filter wrench.
Apply a thin layer of new oil to the rubber seal of the new oil filter.
Install the new oil filter and tighten it according to manufacturer specifications (usually hand-tight plus 3/4 turn).

3. Replacing the Valve Cover Gasket

Tools Required: Socket set, torque wrench, gasket scraper
Remove any components obstructing access to the valve cover (e.g., air intake duct).
Unscrew the valve cover bolts and carefully lift off the valve cover.
Remove the old gasket and clean the surfaces with a gasket scraper.
Place the new valve cover gasket in position and reassemble the valve cover, tightening bolts to the specified torque (typically 7-10 ft-lbs).

4. Inspecting and Replacing Seals

Tools Required: Socket set, pry bar, seal puller
For the front main seal, remove the crankshaft pulley and timing cover as necessary.
Use the seal puller to extract the old seal and clean the sealing surface.
Install the new front main seal, ensuring it is seated properly.
Repeat the process for the rear main seal, which may require removing the transmission.
