When was the last time you cleaned up, and changed out your PCV system? Search the threads if you need to find more info on this. Our cars do not have a traditional PCV valve.

You should replace it, not clean it. Visit FCP for the kit.

You should also replace the gasket on the filler cap AFTER checking the PCV system. They get brittle and will fit loose after a while. That is not a bad thing because if the crank case pressure increases because of a clogged PCV system, it is better to blow off that pressure from the filler cap than damage a crank seal.
