My wife can't figure out why I spend so long in the bathroom.
Mostly the easy-to-get-to wires under the hood. Going to try the more obscure "poke em with a stick" ones today. We also tried jostling the XJ back and forth to no effect. It does seem electrical, the way it just suddenly cuts. I just took the Jeep around the block, and go figure there is no sign of this problem when it's cold. Going to warm it up and try again.

Does this sound like a bad driveshaft u-joint to anyone?
Pulled the front shaft to isolate the noise. Comes on under load in lower gears. Light throttle cruising, it isn't there. U-joint at the differential was replaced within the last 6 months. I have a AA SYE, so I'm thinking it's one of the u-joints at the double cardan joint. For what it's worth, the transfer case was freshly topped off with fluid.

There's the coolant leak
I've been losing coolant very slowly, and worried about a head gasket leak because the PO had removed the thermostat and hard wired the aux fan to run all the time. After I fixed that stuff, I never came close to overheating, and there's no sign of oil in the coolant or vice versa, or leaks at the hoses, or white smoke at the tailpipe. Today I found it... drivers side, back of the engine, low... can't see exactly where it's coming from, but is head gasket a good guess for a leak like this?

No, I don't lick fish.
That, or a freeze plug. Either way, you're looking at removing the head. Not a disaster though, just follow the FSM and you'll be fine.

i need to replace my transmission lines because they started leaking. from what i understand i can cut the metal lines, flare them and use 5/16" rubber trans lines to plug into the radiator with a couple fittings? anything else? i didn't look into getting new lines since that would probably cost a lot more (edit: just checked rockauto, about 35$ per line, so yeah if i could save the money it'd be great, as long as it doesn't leak again!).

I've done this many times on other vehicles with no problem. Unless these transmissions develop unusually high pressure you should be OK. Use good-quality clamps.

Alrighty folks. Idk what kind of sorcery this is. But I was workin on my jeep today, and with the engine running if I pull the dip stick out and put it back in the engine cuts off.
It does it as soon as I put it back in and I can start it back up and do it over and over. It does it every time. If I slowly put the dip stick back in it doesn't.
Anybody heard of this or know why this would happen? lol

Also. It doesn't do it when I pull it out. Only when I put it back in.

Been considering that.... but all across this forum you read dire warnings about it. Folks say it'll kill your water pump and/or radiator. But I have been thinking about it.... you think a little bit is safe & possibly effective?

When I had a coolant leak it was the freeze plug or rear of engine block. Coolant would leak from bell housing.

Oh God don't. You'll create more work for yourself in the end. Seriously, pulling the head and replacing the gasket is NOT that hard. Time consuming, yes. But seriously it's not that hard.
