Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to avoid electrical issues while working.

2. Identify and Fix Oil Filter Leak

Tools Required: Oil filter wrench, new oil filter, oil catch pan
Remove the oil filter using the oil filter wrench.
Inspect the rubber O-ring on the old filter for damage, which may have caused the leak.
Apply a thin coat of new engine oil to the O-ring of the new filter.
Install the new oil filter, tightening it by hand until snug, then add an additional 3/4 turn.

3. Address Valve Cover Gasket Leak

Tools Required: Socket set, torque wrench, gasket scraper, new valve cover gasket
Remove the bolts securing the valve cover using the socket set and carefully lift the cover off.
Use the gasket scraper to clean the mating surfaces, ensuring no old gasket material remains.
Place the new valve cover gasket onto the cover, aligning it properly.
Reinstall the valve cover and torque the bolts to manufacturer specifications (typically around 10-15 lb-ft).

4. Tighten Oil Drain Plug

Tools Required: Socket set, torque wrench
Inspect the oil drain plug for tightness.
If loose, tighten the oil drain plug to the manufacturer’s torque specification (usually around 15-20 lb-ft).
If the plug is damaged or the washer is worn, replace the plug and washer.
