I suspect one of the rollers on one of my lifters is just starting to go bad. I get an intermittent very light ticking at idle that comes and goes not near this bad. It’s not a low end knock/squeak and it’s not a sparking noise for coils/wires. I’m hoping if I tear into it asap and stop driving it I can catch it before it ruins the camshaft. Has 230k miles and never had lifters done yet, 2015 Tahoe LT. Most noticeable at cold start idle, changes with engine speed but goes away as the engine gets to say 1400+ rpm. Other times it goes away on its own at idle so I’m guessing it’s bound to be the roller going bad on one of them
Phoenix has some electrical issues right now that I replaced the tail lights because I had it on warranty and the driver side tail lightI replaced some fuses, and that really messes things up. My tail lights driver's side doesn't work. My mirror turn signal doesn't work

That sounds likely. It could also have broken exhaust manifold bolts cause a tick noise when cold.

Thanks!

Dang sounds like you need some diag. What kind of car?
it turns up my replacement LED tail lights has a broken circuit in it so I'm going to put my old OEM ones back in today
@danielb-c9100 LEDs seem to cause a lot of trouble on cars these days.
typical GM😂
