Just switch out the valve cover gasket in the Trax. Sounds better however, now we have a fume smell.

So, after re checking the engine. We noticed that the oil cap that came with the new valve over gasket was missing, glad I kept the original one. After researching I found that there's a "neck" on the original oil cap unlike the new one.
