Here is a video of a clicking/ticking noise i have on my 1995 XJ 4.0L. I cant seem to figure out where its coming from. Please help me figure this out! I am trying to get this XJ tip-top before I start my build.

Hmmm Sounds like Lifters, but when you got closer to he tranny/rear engine it sounded louder.

That is why i am somewhat worried. It is definately louder underneath, at the rear of the engine, next to the tranny. Maybe its time to pressure wash under there and put her up on craigslist.

Yeahh it could be that #6 rod bearing is bout to go out. Not good. But i would keep on Diagonosing it, have you tried getting close to the lifters and hearing it? or does it sound louder in person on the bottom by the tranny?

Or it could be that the torque converter to flexplate bolts are loose if it's an auto trans.

Its to loud for it to be the Torque bolts. I stand by my opinion, its either lifters or #6 rod bearings.

It is definatrly louder in person near the tranny. I am not a mechanic by any means, but after watching a lot of videos online regarding lifters, I am somewhat sure it is not the lifters. I have also searched this forum a lot trying to diagnose this sound. How do I check the torque converter to flexplate bolts? I have basic tools and no mechanical experience other than brakes, oil changes, tune-ups, and belt changes. I am willing to get dirty if the job can be done in the driveway.

Loose torque converter bolts sound just like a rod knock. Which is easier to check (20 minutes max) and very likely to be the problem?

To the OP:
Where the engine meets the trans there is a 1/4 moon shaped tin/aluminum plate. Remove it and shine a light up in there. You will see one of four bolts with a 15mm head on it. See if it's loose. If it is, remove it, add LocTite 242 to the threads and reinstall it tightly. Rotate the engine around and do the next one the same way until you've done all four bolts.

Well if that is it, then let me know, so that i can go back and study 5 more years of auto tech.

Never took auto tech. Just speaking from experience of 12 years as Service Manager and Shop Foreman at a Jeep dealership when these were new.
Still own and work on them regularly. Bought myself a Cherokee that sounded like it had a rod knock. Tightened up the bolts and we're still driving it.

Thats good, well hope he gets his problem fixed.

That's been my hope right from the start.

Can anyone post a link to a picture or a video that will show me how to find the torque converter to flexplate bolts? It very well may not be the problem, but it is worth a shot since I can do it in my driveway. If it is a rod bearing, I will be unable to fix that myself since I don't have many tools or the experience necessary.

Did you read Post #8? Get under the Jeep and have a look.

Is this the Flexplate Inspection Cover you are talking about. Sorry if I sound dumb, but I am not very mechanically inclined.
