2012 1500, 5.7 Engine Tick

[RAM0359]

75K miles - 5.7 Engine tick just started on startup and goes away after about 10-15 seconds. In southern NC where it doesn't get that cold but temps just started getting cooler by about 10-12 degrees. From reading posts, sounds like broken manifold bolts. I will check those. Does the sound stop because the manifold metal expands when it warms?

Try capturing a video of it

Yeah video, and no it happens because the bolts are bad. If the cadence changes after an oil change it is likely lifters, but it is very possible at 70k those bolts are bad.
