Trailblazer engine tick

Okay, first things first. Where exactly does the sound seem to be coming from? Top end I'll assume? Front? The Timing kit. Along the entirety of the Head? Most likely Lifter tick. From near the Intake Mani? Injectors.
If you can find one cheap, go get a mechanic's stethoscope. I think Harbor Freight has them cheap. Otherwise, place the tip of a screwdriver on the suspect areas, and put the handle to your ear. Works well as a readily available 'scope. I'd need more information to be able to give you a better idea of what to look for though, so get cracking. lol.
That said, if it's from the bottom, it could be a whole bee's nest of things. But most of these will not begin to show as a tick.
Edit:
Noice!

so, unplug fan solenoid and see if the noise goes away

Disconnected the plug on the shroud, and it still ticks. Is the fan supposed to spin also while its unplugged?
I have seen a few things on the early 4.2's.
the valve guides had issues on some of these, but usually crop up as other problems.
I had one I had to tear down & found a lifter galley plug in front of head pushed it's way out of it's bore.
That lost pressure up top & ticked like crazy.
Made sure all the spark plugs are tight? Seen a many weekend DIY'r throw plugs in & leave them loose. They can make noise too.

the salesman emailed me thanking ne fir buying the car. I emailed him back what was wrong and he said he'd talk to the used car manager.
I called Chevy this morning and the first thing that he said was fan clutch relay.
I suppose it could sound more of knocking rather than a tick since it does sound like a diesel and diesels knock.

Pretty sure the return policy is at the discretion of the dealership. The state doesn't have any policy like that, as stated in this doc. I recently used this when buying my car to prove to the dealer the bullshit fees they wanted to charge me are not state required.
