  1. YJ Wrangler Technical Forum
    Long time listener, first time caller. I'll try to make this short. I have a 1995 2.5L 5 speed manual. Rebuilt the entire engine due to a blown piston skirt. Had about 215,000 on it. I also added a 2.5inch lift running 31x10.50. Started up and ran fine the other day after a 4 year sit while I...

    1979 Jeep cj5 with the 258 in it. Bought the jeep not running and bought a brand new engine for it. Installed the engine and it ram awesome for about 50 miles until it didn’t. Wouldn’t start up at all, but turned over. Compression test results starting with cyl 1 we’re as follows: 0, 20, 90...
  3. Jeep CJ Forum
    So I got my 304 running good at idle and it’s drives smooth. The only problem I am having right now is backfire out the carb and bogging when I do a hard acceleration from idle. I’ve boiled it down to timing and I’m wondering what the timing on a stock 304 is, initial and total? I’ve had it at...
  4. YJ Wrangler Technical Forum
    So long story short, I bought another YJ about a year ago because I'm an idiot because I was itching to tinker on something. Ever since I bought it it has had what I can only describe as a "clatter" that never seemed to be that big of a deal and still doesn't. Seems to run and drive just fine...

    Hi All I have a 2000 WJ that threw a piston through the block back in March. I bought an ATK stroker to swap in, have it installed, troubleshooted a few issues, and cant seem to find my way around this one. With the new engine I replaced the crank sensor, cam postion sensor, oil pump drive, oil...
  6. ZJ Grand Cherokee Forum
    Now I did it. Will not start, no compression. Ok, for the long version. I was having low compression on cylinder 1. So I decided to change out the head because I believed it was a valve issue. I had a donor head resurfaced. When I took it all apart it appeared the head /valves were not the...
  7. Jeep CJ Forum
    So, I have been crawling through the forum and I had a issue with my jeep having a strong strong fuel smell. So I read up that it can happen with clogged jets on the Carter BBD. So I took it off, cleaned it up and rebuilt it. The strong smell went away, but I still have a light fuel smell. I am...
  8. YJ Wrangler Technical Forum
    Working on a new YJ (1995 4cyl automatic) that wasn't running when I bought it. Previous owners said it ran but really rough, and it was due to the distributor being 180deg off. I popped off the valve cover, set to TDC (double checking the #1 valves were correct), reinstalled the distributor...

    My dad, my brother, and I have been restoring our 1991 2.5L 4 cyl YJ as a family project. We've spent the past few months troubleshooting a rough running engine with sputtering and power loss and we could use some help. We tried to fix it by replacing parts and installing new sensors. Now the...

    Hi everyone, I'm not new to Jeeps, but new to this forum. I recently replaced my timing chains/gears on a 2005 Jeep GCL 4.7l. It was a relatively easy job and I've done several of these on other cars and motorcycles. The issue I'm having is that the two marked links on the secondary chains...
  11. Jeep CJ Forum
    I have a 1984 CJ7 with a fresh rebuilt 258 4.2. .030 pistons, new exhaust valves, new springs, new cam (OE), new lifter, new timing chain set, D.U.I ignition, new Live Wires, and a new weber 38 carb. I am running the stock fuel filter and new mechanical fuel pump. I have one hose from the...

    Backstory: My brother had a nice automatic YJ, he had an exhaust leak, the heat ignited some oil, it caught on fire, he put it out almost immediately with an extinguisher. All the fire damage has been fixed and it was started after the repairs were made(barely started but it started) but the...
  13. Jeep CJ Forum
    I recently purchased a 1981 Cj7 with a 258 and the original Carter BBD. I think the distributor and the ignition and electrical system are stock, but the PO removed the original air cleaner assembly and it currently has only a 4" open air filter on top of the carb. He also took the EGR out of...

    Ok so i have a 98 xj and i recently rebuilt the engine. DNJ full rebuild kit, header, high flow cat, and flowmaster 40. Now that the engine is back in it runs horrible, when i start it it feels like it has a race cam in it and runs extremely rich. the tach bounces around and if i try to rev it...
  15. XJ Cherokee Technical Forum
    This is only my second post to this forum, so please bear with me. Had to get a remanufactured engine. Only way to get 3 year 100,000 mile warranty was to go thru certified dealer, and to big a job for me. First engine they got, the dealer said there were ignition timing issues, and had to...
  16. YJ Wrangler Technical Forum
    There's the "thud" sound of muffled pop corn coming out of the exhaust. The RPM not idling evenly (I know it's a hair of a difference but I know that's not right) And finally The rattle noise that comes on from 2000rpm~3000rpm rev. I don't know if this is normal. The thud from my research shows...
  17. KJ Liberty Forum
    I have an '02 3.7. It started rattling, so took off valve covers to find out the passenger side timing chain was bouncing and hitting the upper nylon guide causing the noise. So, I tore down the front and took off the timing cover to find the tensioner had basically fallen apart - the...

    So I have been having a leak in my 97 ZJ for a couple months now. I have changed the water pump, upper and lower rad hoses, and the thermostat and housing and it still leaks when the engine cools down. My next best guess is the timing cover gasket is blown. What I don't know is if I need any...
  19. YJ Wrangler Technical Forum
    Completed a 4.0 head swap on my 1989. Everything is hooked up, the computer isn't throwing any codes out besides 12 and 41. It's not turning over, besides popping once every few cranks. spark plugs are all wet when I pull them so the injectors are working. Grounding the plugs on the battery...
