My car doesn't seem to tick all the time (but lately it has been ticking more often than not). When I hear ticking, I either hear it at idle (when fully warm), or around 1400-1500RPM (not noticeable at all around 1200-1300RPM, or anywhere above 1500RPM). The tick sounds like it could be coming from anywhere (most noticeable when I open my driver side door, sounds like coming from the bottom of the car). But when I open the hood it also sounds like it's coming from there too.

The car still runs strong with no SES light. No driveability issues, and no additional vibrations from the ticking. The engine oil has always been changed no more than 2000 miles each interval with Mobil 1 5w30, with 31500 miles on it now (magnetic drain plug didn't have any heavy metal chunks, just the normal metallic particle covering the tip of the plug).

Do all LT1's experience ticking? I had the car since new and it seems that I always had some kind of ticking (actually had the lifters replaced at 3500 miles because the dealer thought that was making the noise).
