VEHICLE: 2001 XJ Sport 4.0
I start the jeep in the morning to take the kids to school. It's cold out (20-30 degrees). I'm used to the whistle the engine makes. Drive about 1/4 mile at around 2k RPM's in 2H (~30 MPH) and I start hearing more of a whining sound, kinda like a gears whining sound. It does it for about 10-20 seconds then goes away. Started doing it about a week ago.
Maybe the oil/fluid is still cold or low?
I posted this on Jeepforum.com and still waiting on some responses. Figured I'd post here too...
TITLE: Identify sound please
Installed my CB a while back (still want to make some mods to it.) I don't really use it much but I was wondering are off roaders still mostly using channel 4 or is that a thing of the past?
JPFrog tends to use Channel 16 (4 x 4). If part of a large trail ride, each group will choose a channel for the day. Helps when different clubs already run on preferred channels.Installed my CB a while back (still want to make some mods to it.)

Attention XJ owners:
I'm looking for someone to give me some pointers. I am planning on buying my coworker's 2000 Sport, 4dr, 4.0L. I've read several "buying guides" on jeep forums, but I'd like firsthand knowledge. It would also be nice to get a good estimate of what to pay. My current car is a manual 96 BMW 328is. It will be great to have a two reliable cars on both ends of the autosports spectrum v
Keep in mind, the 2000 and 2001 are know for cracking heads....some crack and some don't, just a roll of the dice. I also think they went low pinion on the front axle as well.
The jeep has 116k on it. Is there any way to tell if its got the early build "0331" head on it? I'm sure she'd let me pull the valve cover or test the oil prior to the sale.

It's stamped on the head, no need to remove valve cover to identify it.
Chances are likely it will have the 0331 head unless you lucked into an xj with a redesigned head or an 0331 head that been taken care of. Not allowing the jeep to overheat is the best preventive to a cracked 0331 head, but even then, some crack and some don't.
