Cracked exhaust manifold or bad gasket? Is the CEL on? Has your mileage changed?

Could be a crack in the exhaust manifold. When cold the crack can open and cuase the ticking, onc e it heats up and expands it closes enough so you don't hear it. It could also be a lifter. I had a lifter tick in the 4.2 pretty bad. it took 5 mins to clear up. I ran some ATF in the oil just before an oil change to flush out any gunk in the lifters and did the oil change. I changed the oil again a few weeks later and the lifter tick was gone. That was 2yrs ago.Never came back...

im not sure about all the specifics in all honesty... but i have the same thing happen to my 97 tj with a 4.0... i let my dad(a mechanic of 20 years) look at it, and he said that its nothing to worry about.. the tick wasnt actually in the engine. there is this sensor on the right side of the engine that is kinda circular and you could hear it coming from that, and if you put your hand on it you could feel it pulsing every time there was a tick.. this could be it. anyways.. he said that there is absolutely nothing to worry about, it just gets noisy sometimes.

A poorly tuned engine, or a component that needs replacement can make other things not work right and possibly lead to an unusual noise. Clogged fuel injector, bad fuel, all can attribute to strange noises. So, basically it is probably a good idea to first establish that your spark plugs, wires, rotor, cap, air filter, throttle body, fuel injectors, etc are all in good working order. poor plug wires can have a bad affect, some seem the think they last forever, they don't. Nor do coils, they last a long time, but do build up resistance eventually. Run some high quality fuel injector cleaner in you gas, and try to use better quality fuel such a mobil or chevron gas, gas such as am/pm gas is not a good thing imo. Ok, well, all of this may or may not pertain to the problem, but just make sure everything is in check here b4 you look elsewhere.

I have the whole "lifter-like tick" when I accelerate for the first 30 seconds of driving in my 4 banger after it has set for a while

In my experience on my 4 cyl engine, I could not hear the timing chain slapping around on acceleration. It was only at low idle, then I could hear it.

Your TJ has a bunch of emissions stuff for the ODBII. That heartbeat you hear is a valve in the evap system. YJ's don't have them.

I also get this ticking noise, increases in tempo when I hit the gas, slows when I let off. Difference is from yours is that the ticking only happens after the car is fully warmed up! wtf!
