I've had this jeep for a little over a year now.
2000 Wrangler TJ 2.5L Teraflex Lift, Auto Trans. running 33's.
When I first bought it, it was fine, no ticking or knocking or anything, ran fine.
Until I changed the oil.
At first it was not much of a knock, more like a ticking. I was told that a lot of
Jeeps get it, but over the next few weeks it got a lot louder. I took it to a few shops in which I've been told its everything from a sticky lifter to an exhaust leak.
It's a knock now.
The knock only comes around when it is cold or when accelerating, and you could barely hear it at all once everything has been warmed up and on the move. I've had the lifters changed out, new rod bearings, new distributor cap, new wires, plugs and used injector cleaners. flushed out the thing a few times with sea foam. I'm running a little thicker oil in it and some lucas oil so the noise isn't as noticeable. I think using the thicker oil has caused a little bit of a leak in the rear seal? Noise seems to be getting a little louder. Power has always been an issue (even for a 4banger) a few of my friends have had them too and all of them has more power than mine.
Just wondering if anybody has any ideas on what to do next?
