    broken bleeder valve

    I was going to change my brake fluid today. After soaking the bleeder valvse in PB blaster the first one sheared off. I stopped there. There is nothing sticking out to try to get some vice grips on to work out either. I know I will have to replace the cylinder, but was wanting to replace the...

    Transmission mount nut size

    I tried searching/googling but couldn't come up with anything. Does anyone have the nut size for the transmission mount? I believe it is a metric nut. These are the nuts for the four bolts that attach the mount to the crossmember. This is for a 2000 4.0L 4x4, non-offset mount. I am going...

    Stolen cat converter w/Cali emissions

    **As a disclaimer, I will replace the cat converter** Bad two weeks for the XJ. Had the stereo stolen two weeks ago, went out of town for the holiday and there was a hail storm when I was gone so my hood looks like a golf ball. Then I tried to start it up and it scared the $h!t out of me...

    Still running rough with poor MPG

    Backstory: bought a 2000 XJ with a cracked head, replaced that with a remaned 7120 head from a 91-95 4.0 HO. The guy that did the swap bored out the 2000 exhaust manifold to match the bigger exhaust ports on the 7120 head. It seemed to run ok before the swap, from what I recall. The Jeep...

    Poor gas mileage and rough running

    weird idle with video

    Just had the head changed on my 2000 XJ. My idle was rough before and it's the same after. i was hoping it would be an manifold leak or something but it's the same. Here is a video. It sounds like something is opening up and the engine revs a little higher then settles back down, but the...

    7120 head swap exhaust question

    I am going to have my cracked 0331 head replaced with a 7120 HO head. I bought a new exhaust manifold since the one from my 2000 will not line up. The problem I forsee is I have the Cali emissions package on my XJ, which is the two precats with the four 02 sensors. Can I have the precat 02...

    Chicago area engine rebuild

    I have the dreaded 0331 head crack in my 2000 XJ, 100800k miles. I believe the bearings are shot too, have the low oil pressure when it comes up to operating temp. Needing a used motor to swap in and someone to do it as I live in a condo with no access to a garage, etc. Anyone have any leads...
