Subject: Re: Rocker help by CFI-EFI on 2009/3/26 15:57:25 I have never heard of a noisy rocker being a rocker problem. It is always a loose valve adjustment. If the noise really is coming from a worn or defective rocker arm, don't run that engine any more than necessary. If the rocker arm is so bad that it makes that much noise I would be afraid it is ready to break or come apart sending shrapnel and small parts through out your engine. Adjusting the preload of the lifters with the engine running provides the most dramatic indication of zero lash. This can be convenient when you are setting the preload to near zero for minimum pump up. Near zero preload is NOT a good idea for a DD. The fact that yours makes noise indicate that you didn't miss zero lash and tighten them too much. At this point, I think I would simply tighten the noisy lifers with the engine running to assure you had found and corrected the problem. RACE ON!!! |
