  1. XJ Cherokee Technical Forum
    Recently purchased a 2000 XJ w/ 112,000 miles and after 2 weeks, a couple bad idles, and a code read (Cylinder 3 issues) I changed the spark plugs. A couple days later and misfire I noticed low coolant. I'm not very knowledgeable with engines, so I read up on the 0331 head and felt a little dumb...

    Is this block garbage/warranty? I was about to bolt on the head/gasket and found these cracks in the webbing between where the push rods go, where the webbing connects the side of the block to the cylinder. I'm wondering if the machine shop didn't say anything because it's not a big deal, or if...
  3. XJ Cherokee Technical Forum
    I just recently picked up a 2000 Cherokee Sport 4.0 for free. However, there are issues with the engine. It starts up fine, but after only a few minutes the engine starts to overheat. The guy who owned it before me just recently took it on a trip from NJ to Maine and told me he had to make...

    Has anyone used or heard about this Blue Devil stuff? Supposed to be a permanent fix to engine leaks. http://store.gobluedevil.com/head-gasket-sealer-38386/ BACKSTORY: I might have a blown head gasket or cracked engine head (coolant possibly leaking as indicated by stinky sweet exhaust and...
  5. XJ Cherokee Technical Forum
    So the cylinder head finally went out on my '00 XJ. With as much work and cost that it is, I'm also a little bit relieved because now it can be off my mind and I won't have to worry about it again once I have it fixed. I also decided that I was going to replace a lot of pieces and parts while I...
  6. XJ Cherokee Technical Forum
    My '99 XJ 4.0 has a cracked 0331 head. I've seen much debate on what to do about this. Many say the newer 0331 heads are cast better and don't crack as easy. HOWEVER, many argue these newer remanufactured heads haven't accumulated enough miles to reach the breaking point. These folks say you...
  7. XJ Cherokee Technical Forum
    When you buy a Cherokee, make sure you inspect the coolant. People are filling their Jeeps with stop leak to cover cracked heads/head gaskets. This will run you anywhere from $400-$1,500 if one of both are bad. It will mess with your heater core, and just leave a heap load of work for you...
  8. YJ Wrangler Technical Forum
    Not sure if this is the best place to put this but I'm new here. My jeep had a leak in the exhaust manifold, which my dad attempted to fix after I left for college. It turned out that the manifold was cracked, so he bought a new one and took the old one off to replace it. Unfortunately, he...

    I bought this engine off of a guy on craigslist, and once I took one of the heads off I noticed that the block was cracked along the coolant passages.:( Any of you guys think that there may be any possibility of getting this repaired or is the block junk now?
  10. TJ Wrangler Technical Forum
    Hey guys a few weeks ago my exhaust got really loud and upon further inspection I found I had a cracked exhaust manifold. It is the two piece style so it is a little rarer than the one piece style but evidently it happens. Sa as a result I decided to be a little cheap (wait this become...
  11. TJ Wrangler Technical Forum
    I know that the 2.5L are known to have problems with cracked manifolds. I have already replaced the manifold once, which was about a month and half ago, and now I think it is cracked again or has a blown gasket. To tell you the whole story in a few sentences, I took the Jeep to Silver lake sand...

  13. TJ Wrangler Technical Forum
    The story: 2000 4.0 with cracked head drove it for years. Had engine rebuilt at 74,717 miles. Mech could not understand the head thing or why he could not fit the coils to an old head he rebuilt or why he could not find a used 2000 head. I went to Clearwater Cylinder Head and bought NEW head...
  14. ZJ Grand Cherokee Forum
    Just finished checking out a few other (and pretty old) threads on this issue and didn't find any perfect answers besides completely replacing the parts which seems too costly for a simple cosmetic defect. Here's my plan. My idea for the front door arm rests is to cut the area to a rectangle to...

    I have a 96 Jeep Sport 4x4 with the I6. My girlfriend drove it for about 5-10 miles with it over heating because the upper radiator hose was split. Anyways I was hoping I'd just have to take off the block and change the gasket, lo and behold the 2nd piston is missing a chunk. The wall doesn't...
  16. XJ Cherokee Technical Forum
    Should I buy a new remanufactured one or have the old one machined? If you've bought a remanufactured one any recommendations? Thanks in advance.
