Hi, wondering if there is a fix I could do to stop the rattle/tinging of these spring loaded valves or what ever they are called. They are part of the AFM (active fuel management), they engage when engine does not need all 8 cylinders and disengage when they are needed. Thing is when not engaged they rattle/tingle and very annoying, can hear it inside the car even with the top up. Can these be removed or something or will it cause major problems down the road? It seems they weren't tight enough and then rattle, I was thinking about putting something there to make it tight. Like a piece of high temp rubber?
Anybody have ideas? It's not a warranty issue or recall as its part of the L99 cars.
