Hey guys, I've been noticing a tapping sound anything over 2000rpm. I'm certain it's not detonation. My timing is at 10* and I'm running nothing less than 91 octane with 39psi.
Now day before yesterday, my dad and I set the base timing from 25* to 10* (Wow, I had no idea), to prep for the JMS chip. The chip is not currently installed. The sound, however, was occurring before we adjusted the timing.
I never heard detonation with that much advanced, but could have something been damaged? Or could it simply be a rocker hitting the valve cover?
Any ideas? Things to check for? Thanks.
