Sounds like your lifters. Hydraulics might be getting a bit weak. But, I have never heard a ticking 4.0 or 2.5 that I didn't love

Seriously, probably nothing to be concerned about. Even my new 4.2 had a lifter tick.

Mine has the same "tick" and it is caused by the lifters as Falatude said.

My '94 ticked for all of the 30 or 40k I had it. I adjusted the valves a couple of times to no avail. Always ran strong, though.

I wouldn't worry about it as long as it is moving. I pulled my oil pan when I got my 89 yj last year and found parts or the number 2 and 3 piston skirts in the bottom of it. I have put 20 thousand miles on it since then and it is still ticking. Doesn't burn oil or kock, Just has a slight vibration from the off balance of the rotation. I will drive it till it blows up but in the mean time it runs 75 miles an hour on the highway and takes me into the woods and out as needed.

Yeah its a lifter not building compression. Almost every Jeep owner I know has had that happen to them, but its nothing to worry about. It annoyed me for awhile and I even went as far as to change all my lifters. It quieted down for awhile, but its back again. Kind of a badge of honor really.

too stop the lifter noise in my 95 YJ I put a pint of automatic tranny flude in the oil pan, ran it for 100 miles and then changed the oil, tick is gone, for now but it will be back.

In an older motor with over 200,000 miles on it, and smoked through the vales and rings, I put a can of restore in the oil each time I changed the oil, it stoped smokeing and had little more power, I drove it that way for over 5000 mile before I sold it and it's still out there and still running on the same motor.

Got the restore at what use to be Sucks for the 4 cylinder, this can is for a 8 cylinder you can allso get it for the 6 cylinde.
