The tick I can say, is not an exhust sound as it's coming from the other side of the engine (intake side). It also is below the valve train. I didn't spend much time due to frustration, but it sounded like is was in the area around the oil pump.
I haven't taken it on the highway. I'm a bit weary to run it more than necessary so as not to cause any damage.

95+ 2.3L engines have a oil pump that's driven directly off of the timing belt, unlike the older ones that had a conventional shaft driven off of the distributor or stub shaft.
I can't recall hearing anyone throwing a rod on a STOCK 2.3L engine. The bottom ends are just tough as nails. I'd attribute it more to valvetrain noise or an injector tick.

Geez, the only thing not mentioned yet is the injectors. Noid lights cost less than $10 per set to check the pulse from the ECM. Or you can take them out and check that they are clean. A shop can run cleaner thru them if they are clogged for about $75, depending on your local rates.
You can also use your ejumacated finger to feel the pulse as each injector is energized. Missing pulses could be telling.

I'm in the process of changing my timing belt. I never had any problems out of my truck before this. Now, I'm certain I'm off a tooth. Idk where tho, I've tried setting it forward a tooth, I've tried setting it back a tooth and I am stumped. Sorry if I'm hijacking part of your thread chelmer, but I have to ask you.....
My truck cranks, I am yet to drive it, it idles normal, but when I give it any throttle, the RPMs will dip and then they'll go up. Does this sound like a timing issue? Maybe it's the CPS. Coil packs? Someone, pls help me... I've spent way too much time on this and I've gotten too good at pulling the front of my motor off.
Btw, it's a 1999 2.5L L4.

Was just trying to see if I could apply any of this information without taking up too much time from anyone else posting to my meager problems.
I must say, it's fixed now!
I finally got someone to help me. My brother was driving the truck when the belt went, though I can't blame him for it, he never managed to even come out and offer to help me fix it. I ended up undertaking the task all alone and then my dad managed to get off work before I went to work, so we got it knocked out quickly. It runs like a champ now.

I haven't had any time to get back to mine....but curious what you found to be the problem natebaker?One thought I did have on mine though, my next step is to check the injectors; although it smells rich when it's running so I don't expect that'll be my problem?

Timing was off. Off by a tooth. I had a little hesitation on my throttle, but that was due to not having the radiator hooked up and the engine never came up to temperature, so it was still running rich bc it was in the 'cold start' mode. Everything is great now.

Just another thought...on our '06 Econovan at work...couple months ago two injectors went bad on it...so when you gave it some gas...it would try to die before going...and that didn't matter if it was hot or cold.

Problem Solved
It's been awhile since posting on this issue as I haven't had time to work on it.
Anyhow, the problem is now solved and the truck is running better than it ever has since I've owned it.
The problem was a VERY STUPID one on my part. The timing marks on the cam and oil pump are actually a little triangle and diamond. These marks were covered by dirt and what I thought were the timing marks really aren't. These little dimples (or whatever you want to call them) apparently don't have anything to do with lining up the timing.
Figured I'd go ahead and expose my dumb mistake here in hopes that maybe somebody can benefit someday.
Thanks to all who provided input, it was very much appreciated.
