My 95 started to after the second oil change in a new motor. I was running Q-horse power and a K&N oil filter. The next day I changed my oil to a different full syn and put a Wix filter on. I have never herd it since. But my 95 and 99 have a leak in the exoste manifold and I hate that!

Mine has 163360 miles and it does not knock, but it does have a slightly cracked manifold. I still get between 20-23 mpg.

My 98 knocks a bit at idle. Always has. Bought it at 200,000 KM'S now has 265,000 KM'S.

Only when I forget to unlock the door. Bad puns aside, nope. My engine sounds mint. It idles better now that I have properly gapped plugs in there too.

My 99s 4.0 started knocking a couple hours after i bought it back in fall 2007. I was HotRodding her around that night, but Ive HotRodded All my Jeeps, and none of them have had any Knocks,...Yet! Ive put 5,000+ miles on her since then.
