What is that weird ticking noise I hear coming from the engine area/under the car when I start my car up in the moring. It last for about 5 minutes I think, I am not 100% sure where it is coming from and I am not 100% sure the cold is what effects it.
I have a 2004 Grand Cherokee Laredo 4.0l so its fairly new. So what do you guys think that ticking noise could be?
I have same WJ... Mine started doing the same thing this winter... I was told its lifter noise. Nothin really to worry about, just the valves clickin because of lack of oil when its cold. Try switching to a lighter weight oil might help it some. I am runnin 10w-30 Mobil1 I think 5w-30 would be better.

I've got the same thing. I'm pretty sure it's a cracked exhaust manifold though. It used to only be there when the engine was cold, now it starts very loud when the engine is cold, and continues, only more quietly, when it warms up.
I wanted to know what it was once so I started the jeep and opened the hood. It sounded like it was coming from the bottom of the drivers side of the engine (I have the V8). The sound is directly proportional to engine revs, so I think I have a cracked manifold. I'm gonna have the stealership take a look at her soon though.

had four jeeps with the 4.0L. one grand cherokeee and 3 wranglers. both my current GC and my dad's 04 wrangler made this noise on start up. my dads jeep did it year round on cold starts. my GC only does it on sub 40 degree mornings.. just always figured it was a "jeep thing"
