- Carefully lift off the cover and set it aside.
Inspect Valve Cover Gasket:
- Check for any oil seepage around the edges of the valve cover.
- If leaking, remove the valve cover by loosening the bolts in a crisscross pattern.
- Replace the valve cover gasket with a new one.
- Torque specification: Tighten bolts to manufacturer-recommended torque values.
Inspect Oil Pan Gasket:
- If leaks are found at the oil pan, drain the oil using an oil catch pan.
- Remove the oil pan by loosening the bolts; clean the mating surfaces.
- Replace the oil pan gasket with a new one and reinstall the pan.
- Torque specification: Follow the recommended torque values.

3. Replace PCV Valve (if necessary)
