What You Need to Know
- Inspect the valve cover for visible wet spots or oil droplets to identify the source of the leak.
- Apply RTV sealant as a temporary fix for minor leaks, ensuring proper application to avoid further damage.

- Use a spark plug socket to remove and replace spark plugs, and clean mating surfaces with brake parts cleaner.
Identifying the Leaking Valve Cover
Check your Nissan X-Trail’s valve cover for signs of oil leakage, as it’s often the first indicator of a failing valve cover gasket.
When inspecting the valve cover, look for visible wet spots or oil droplets around the cover and surrounding areas. These leak symptoms can indicate that the gasket is no longer doing its job, allowing oil to escape.
A burning oil smell is another sign of a leak, and if you notice it, you should investigate further.
During your gasket inspection, also keep an eye out for a check engine light, which can be triggered by misfires caused by oil contamination in the spark plug tubes.
If you find oil in the spark plug tubes, it’s essential to replace the valve cover gasket promptly to avoid further damage to the ignition coils and spark plugs.
