Message I've noticed this for a few weeks now, and stupidly didn't think anything of it until now. There is a very consistent ticking noise coming from my engine. It sounds almost identical to a ticking clock or stopwatch. It's at a consistent interval, not incredibly loud, and only audible when the car is sitting at a stop or whatever.

The idle is very stable and consistent, sits at about 900rpm. The car feels and drives fine. From searching around it seems like maybe lifter tick? I have no idea what engine knock sounds like, and looking up videos online is not helpful for this. Anyone have any thoughts or suggestions on this? Is this dangerous? Thanks!
