2. Fix Oil Filter Leak

Step 1: Remove the oil filter using an oil filter wrench.
Step 2: Inspect the rubber O-ring on the old filter for damage.
Step 3: Apply a thin layer of new oil to the O-ring on the new filter.
Step 4: Install the new oil filter by hand, tightening it according to specifications (typically hand-tight plus a quarter turn).

3. Tighten or Replace Drain Plug

Step 1: Place an oil catch pan underneath the oil pan.
Step 2: Using a wrench, check the tightness of the oil drain plug and tighten if loose.
Step 3: If the drain plug is damaged, remove it and replace with a new plug, ensuring to use a new washer if required.

4. Repair Valve Cover Gasket

Step 1: Remove any components obstructing access to the valve cover.
Step 2: Unscrew the valve cover bolts and lift off the valve cover.
Step 3: Remove the old gasket and clean the mating surfaces thoroughly.
Step 4: Place a new gasket in position and reinstall the valve cover, tightening bolts to the recommended torque specification.

5. Inspect and Replace Seals

Step 1: If leaks persist, identify which seals need replacement (front/rear main seal).
Step 2: Remove any components blocking access to the seals.
Step 3: Carefully remove the old seal using a seal puller.
Step 4: Lubricate the new seal with engine oil and install it, ensuring it sits flush in its housing.
