Well if you're lifted enough that the slip yoke doesn't have much spline engagement, yes, sticking a longer factory DS would get you a bit more in. Depends on your setup though. If you can get one CHEAP it might be a nice hold-over until you can throw an SYE and double-cardan shaft in.

Longer driveshaft works fine but you need to be careful about the length. A D35 shaft is a little longer than a D44 and C8.25 and can be enough for a small lift if you have either of those axles. A driveshaft from a manual trans will add another couple of inches.
Another option is use a longer slip yoke. I found this long one on a YJ at the junkyard, some people have had them on XJs too, no idea what the origin is. It has longer ears which adds overall length and also helps articulation with steeper angle. I ran it for quite a while before installing the SYE, never had an issue.

I have 4"s of lift. I never experienced vibes (that i noticed) and my U joints haven't trashed yet so I'm assuming i'm fine. I have a d35 by the way, '88 XJ. Don't have any pictures of my driveline angles, just thought it was a neat point in the differences in length.

Any specific fuse thatd cause my front overhead lights to never turn off and kill my driverside foot light? If its just busted wiring I am going to ignore it.
Any authoritative source proving: all XJ 4.0 HO 190hp engines are the same?
Hi, does anyone know of a somehow authoritative source to convince vehicle-registration-tax-people that all XJ 4.0 HO 190hp engines are the same? ...from 1991 to 1999?
I am struggling to prove that my 1991 XJ is emission-wise the same thing as the 1996 and newer models that have at least EuroII emission stamps. I guess anything from a manufacturer or an association would do...
Thanks for any suggestions!

The other thing is that there is a difference in emissions performance and compliance between OBD-I and OBD-II models. For example, most (if not all) of the OBD-I XJs do not have downstream O2 sensors. Also being OBD-I, the modern "plug it in and check monitors" style of testing does not work.
What is it you're trying to accomplish? Get an entire vehicle registered and tested or have an engine swap certified?

Basic electrical question:
I want a three position switch to run two lights as follows:
Position 1: Light 1 on
Position 2: Both lights on
Position 3: Light 2 on
What am I looking for in electronics terminology so I can find it? Relay/amperage isn't an issue here; just the switching aspect.

2000 Cylinder Head
First off, I want to say thanks to everyone on this forum. If it weren't for this group of people, i would have surely pushed my jeep off a cliff in frustration on more than one occasion .
I recently discovered a big crack in my poorly put together homebrew cold air intake and noticed that there was a whole mess of junk in my throttle body and intake manifold (mostly oily, also due to a clogged ccv/pcv). I kept digging deeper, cleaning out the sludge, one thing led to another, and now I have my cylinder head off and siting on the work bench.
It is a 2000 XJ Sport 5-speed with the dreaded 0331 Cylinder head. I'm wondering if it's worth putting back on or if i should just bite the bullet now when it's already off and replace it with a new beefier one. How likely is it that this is going to crack on me any time soon?
I've never had any notable coolant loss, there's no cross contamination between coolant and oil, the head gasket was completely intact, and there are no visible cracks in the cylinder head. It has been overheated before and it's warped maybe a couple thousandths in the middle. If I didnt replace it, I would get it machined and Lap the valves, I just don't want to put money and effort into a flawed part if it's going crack on me in the near future
The Cherokee has about 125,000 miles and i plan on keeping it for as long as i can.
Thanks for any and all advice!!

It wouldn't be a bad idea to swap the head out of you can swing it. I'm not saying that your current head will crack soon if you don't, but it would be good peace of mind. If you have the head decked and do the head gasket on your current head im sure it would last a long time. That's going to be up to you.
