Hi all.
Just found the group and am inquiring for a friend. He has recently had his engine rebuilt. When he got it back from the shop, it had, and still does, a lot of top end noise. At first we thought it might be the valve/rocker clearance was not set right but being a DOHC, there isn't any clearance there. We also didn't have the means to pull the engine so we couldn't check to make sure everything was torqued right. After a closer listen to the engine, it soulds like it could be a connecting rod. It sounds like a loud tapping noise. Any suggestions? Any info. would be greatly appreciated.
Thanks in advance, Brad
