A while back I noticed noise coming from my engine when the car was idle. It sounded like a "marble in a can" like Peterson said. Once I was driving the car the sound was not there anymore and when I hit the brakes and the car was idle again the sound came back.
Peterson said it was the timing chain and the upper guide making the noise. I purchased the valve cover gaskets and decided to remove the upper timing chain guide.
It was very easy. I just drove the car for about 5 miles came back to the house and checked the car for oil leaks and of course the engine noise. To my surprise the "marble in a can" noise is gone, and the engine sounds smooth and no oil leaks.
I was surprised because Peterson said that at the most just expect the noise to go down a little bit but not completely. Pleasant surprise !!!!!
Thanks to Peterson for his help
