Knocking in Timing Cover
There is a knocing in the timing chain cover of my 2 yea old 427 bbc. We figured out that the cam was walking out and the cam button is hitting the cover. Where do I go from here to stop this noise? Any suggestion??
Welcome to CHR. I think that you need to hook up your vacuum advance. At part throttle when cruising you have less air and fuel in each cylinder, and the air-fuel mixture is not as densely packed...
