Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and ensure the engine is cool.
Disconnect the negative battery terminal to prevent electrical issues.

2. Inspect and Replace the Oil Filter

Sub-steps:
- Use an oil filter wrench to remove the old oil filter.
- Lubricate the gasket of the new oil filter with a small amount of fresh oil.
- Install the new oil filter, hand-tightening it to secure.
Tools Required: Oil filter wrench, clean rag.

3. Replace Valve Cover Gasket

Sub-steps:
- Remove any components obstructing access to the valve cover (like intake hoses).
- Unscrew the valve cover bolts using a socket set.
- Carefully lift off the valve cover, ensuring the old gasket comes off with it.
- Clean the mating surfaces on both the cylinder head and valve cover.
- Place a new gasket onto the valve cover, then reinstall the cover and torque bolts to manufacturer specifications (typically around 7-10 ft-lbs).
Tools Required: Socket set, torque wrench, gasket scraper.

4. Replace Front/Rear Main Seals (if necessary)

Sub-steps:
- For the front main seal, remove the crankshaft pulley using a puller if needed.
- Carefully pry out the old seal and install the new seal using a seal installer tool.
- For the rear main seal, the transmission must be removed. Support the vehicle securely, disconnect the driveshaft, and remove the transmission to access the seal.
- Replace the old seal in the same manner as the front seal and reassemble.
Tools Required: Puller set, seal installer tool, transmission jack.
