I am having a ticking sound coming from under the hood. It does not happen when the motor is cold but it starts to appear as it gets warmer and is constant at operating temps. I initially thought it was in need of a valve lash but I used my stethoscope to listen in and it doesn't appear to be coming from the valve train. I also checked the lash on the side it's coming from and everything appears to be okay. It is definitely coming from the drivers side and I can hear it better from atop the engine rather than underneath. That might be just because it's not as noisy under the hood.
I have a 489 with a comp mag 294s, solid mech lifters. The motor has about 5000 miles on it and I relashed 6 months ago. I maybe have 1000 miles on it since then and am due to change the oil. I have Shell Rotella T 20-50 in there now. How far out of lash in thousandths would it take to cause a tick? Any suggestions.
