Sub-step 1: Tighten or replace the oil filter if it is loose or damaged.
Sub-step 2: If the valve cover gasket is leaking, remove the valve cover by loosening the bolts, then replace the gasket with a new one.
Sub-step 3: Check the oil drain plug; if leaking, use a new washer and tighten to the manufacturer’s torque specification (typically around 20-25 ft-lbs).

3. Cleaning

Sub-step 1: Clean any spilled oil from the engine and surrounding areas using degreaser and rags.
Sub-step 2: Inspect and clean the exhaust system if oil residue is present.

4. Refill and Test

Sub-step 1: If oil was lost, refill the engine with the recommended oil type (typically 5W-30 for many models).
Sub-step 2: Start the engine and monitor for leaks and unusual noises.
