mine ticks as well...just got it 2 days ago, 220 on the odo....

I notice the ticking OFF boost........right at acceleration......lasts only a couple of seconds....


does not do it at idle...only under load


its ONLY at low rpms (maybe I just cant hear it otherwise....).......





My xterra ticks when it needs an oil change.........Im going to just change it next week kat about 500 or so....figure it cant hurt..
