Thanks MudderChuck!! Your assessment was right on...the line from the MAP to the throttle body was so old it was brittle and apparently a slight bump during o ring install made it crack. Got the part at the dealer, installed in about 30 seconds and she's running like a top! In fact, even better...

Hi All, I have an 87 XJ 4.0L fuel injected. Was running and idling fine until... Noticed a significant gas leak from an injector on Saturday. Replaced all the O rings and still had a leak from the top of the injector, so 86 bucks and an hour later, the injector is replaced. Now, the idle is...

Also, can someone please give me instructions on removing the ignition lock cylinder? I have instructions about replacing the switch only. The dealer says when I buy a new ignition lock cylinder from them (they can get it on monday at the earliest) it comes with this piece and the 2 closest...

Thanks for the ideas Mudderchuck -- the battery & cables were new about a week & 1/2 ago, and there was no click at the solenoid, it was the sound of electricity, but not getting to that part of the circuit, which is what lead me to the ignition or the neutral safety. Fantastic idea about the...

Hi, I have an 87 XJ 4.0L FI with 113k on it. had to replace the alternator this summer because oil blew into it from my leak. I am putting in a quart every 1000 miles or so and I'm not terribly worried about it. Put in a new battery a week and 1/2 ago, beacuse old one was getting weak. Had 2...

The transmissions are the same.......computer.......didn't even think of something like that! I have been driving pre 1980 vehicles for soooo long that the thought had never occurred to me. Something more to think about than just the swap. Thanks for the input, I definitely need all the help I...

Okay, I am considering my options here & saw a motor for a decent price out of a '92. Same inline 6 etc. Question: Will this bolt right into my 87? Is there anything I need to know, ie; electrical clips change from the 87 to the 92 (like 4 prong to 6 prong or whatever) or ??? Any advice from...

New Moderator I asked these questions in my XJ woes thread, but no replies to this part of the post, so I thought perhaps it might work better in its own thread. Now here's my dilemma, this is a great Jeep and I love it. The mechanic noticed a leak at the rear main seal & the oil adaptor(?)...

1076497 Hi, Thanks for the welcome! It's an inline 6 4.0L. It's not the fan shroud, its like a fish pan that is under the vehicle and bends up a bit. The mechanic said its trapping the oil and then it is being pulled up and blown out through the fan. So the oil is migrating forward, getting...

1076500 Oh, and I forgot to mention...... The XJ runs great! Flew through a tough emissions, has no blow by and lots of power. Thought I should add that, just in case it will help![addsig]

1077465 <<Now here's my dilemma, this is a great Jeep and I love it. The mechanic also noticed a leak at the oil adaptor(?) but it's not terrible, again typical. He's afraid that if I fix the rear main that it will happen again because there is a valley worn from the crank. Can I replace the...

1076494 Hi All! I'm new here, though I have been reading the posts since I bought my XJ 6 months ago. I noticed an oil leak start about 3 weeks ago, lo and behold it's the rear main seal. Not a huge surprise, but I figure not too serious since the XJ only has 109K miles on it. Took it to the...
