Question 3.2 engine noise

My 2016 Cherokee 3.2L with 35k miles has a tapping/ticking noise under the hood for about a second or two when cold starting. Sounds like oil drained from lifters maybe?
Is this common or should I get it looked at?

Yep, my 2014 does it to (sadly). There are no lifters to make noise though.

Yes, there are lifters in the Pentastar engines. Like any lifter, they can indeed make noise.

I always called them cam followers so to not confuse between older and newer XJ's

Question

Odd, the XJ 4.0 had traditional “lifters” which actually touch (follow) the camshaft. The Pentastar engines in the KL have lifters which are not in contact with (do not follow) the cam. It can be seen in the center of the photo below. Maybe I am misunderstanding you.

I usually referred to lifters, like in the XJ, OHV, where the lifter rides on the cam, and uses the pushrod to activate the rocker arm.

Force of habit I never used the word lifter when talking about overhead cam engines.

(I'm also primarily a Ford guy, so my terminology can be different. I once brought rear end parts for my Bronco, called them "spider gears" and the parts guys thought I was on something.)
