My Z decided to start making a ticking noise when leaving a store one day. It’s never made loud valvetrain noise ever. It wasn’t on a cold start and it’s not at idle like some other posts have said. I’ve tried to research as much as I could before posting this.

The noise: it isn’t a loud rumble, it’s not a “knock” it’s more of a rhythmic loud-ish tick between 2200-4000 rpms on on throttle and stops ticking when the throttle has been let off completely no matter the rpms. I can hold the rpms steady and the noise happens.

There was 5W-30 synthetic oil in the engine unfortunately I was not running ester oil. I switched immediately to redline, and it’s been about 500 miles since the switch. The noise hasn’t gotten worse or better. I’m going to post a video of the noise soon. Power is the same and no vibrations.
