Default Re: Noise in my new 29 a engin

I don't know if anybody mentioned it but it could be a loose timing gear--loose on the cam. I once had a knock that was driving me crazy and even though I was sure the timing gear was tight when I checked it I found it loose. When I tightened it and center punched the nut to make sure it wouldn't loosen the knock was gone. And in my case it only knocked after the engine had warmed.
