Lately I've been noticing valve or VVEL noise that's louder than usual. I can hear it inside the car while the engine is idling (warm). I'm not sure if it's VVEL, valves, or just the larger injectors. The noise is very mechanical, and it's louder on the passenger side. Other than that, the car seems fine. Every once in awhile startup is a bit rough, but doesn't make any valve slapping noise. __________________
