anyone else had this issue? Any ideas what it might be I’m thinking injector but it goes away when I’m driving.
Ticking noise while driving
- Thread starter Spencer Smith
- Start date
So I guess the video isn’t ganna load or work but there’s a ticking noise that happens on idle an comes an goes when I’m driving. It’s a very rapid ticking. I checked the manifold an exhaust no cracks or leaks. I’m kinda thinking an injector but want to see if someone else has had the same issue an what it is before replacing all the injectors
I fixed the video for you.
That noise is lifter tick, it has nothing to do with the injectors at all. The 4.0 engines are notorious for this lifter tick noise. Many of us have it and just live with it. I believe the only actual solution is to rebuild the cylinder head with new lifters.
As long as you can deal with the occasional noise though, it's nothing to worry about.

Yeah that tick is very annoying an I don’t like me vehicle sounding like a lemon lol Do you have a website or preferred shop that you recommend to get the parts from?

My 06 LJ will sound like that on a cold morning once and a while until the manifold heats up a bit.

I bought my 04 a few months ago and it did the same thing. A lot of people here (including me) are 'skeptical' when it comes to oil additives, but I've put Rislone in mine at both oil changes and the ticking, while still there, is considerably quieter. Probably not a permanent solution, but it helps .
Good point, that totally slipped my mind. Usually the lifters only do it on start up (though sometimes they can do it even while running), but in your case it likely is an exhaust manifold crack, since this is very common on the 4.0.
Several ways, but I like spraying water and dish soap around the exhast manifold and see if/where bubbles from.
I've been searching all over the internet for this exact noise. It's only when I'm after 2000 rpms. It does However get better once the engine is completely warmed up. Thanks chris!
Mine has a ticking sound when I am driving or I press on the gas what can that be help mine is a 2002

Most "lifter tick" on the Jeep inline 4 and 6's is actually piston slap (that can be minor or major) and/or cracked pistons that lead to skirt failure like you see above. Every once in a while the noise can also be traced to the wrist pins which eventually leads to throwing the rod through the block. I just replaced all my pistons due to bad piston slap. None of my pistons skirts were cracked yet, but I had visual aluminum transfer to the #2 and #5 cylinder walls.
I just went the route of replacing lifters and pushrods but the tic was still there. Purposely did not drive the thing much in case it was something worse. Pulled the pan and the rod bearings where fairly worn on #3. So out came the engine. Had a cracked piston skirt on #3 so I am rebuilding it right now. I just bored the cylinders and honed them yesterday. Going back together today. I would be very careful with the dreaded tic because you could end up with a rod thru the block or one you have to sleeve.
