Last couple times I've taken my car to get an oil change at the Nissan dealership and they said I need to replace my Valve cover gasket.
So what should I check to confirm and is there such a thing as a minor leak that would not danger my car. I've been driving it for months now with no lack of performance nor oil pressure.

 

Maybe do a little research on here and you'll find it's a pretty common problem.

 

With a name like pussologist what do you expect? You probably need new valve covers and not just the gasket. Good luck Dr
