Looking for some help installing the camshaft. 1977 Jeep CJ7 with a 304. I had the cam polished and the lifters in order. While the camshaft was out at the machine shop, the box holding the lifters fell and lost all order of the lifters. I know installing them out of order isn't a good thing...

2015 3.6L V6 Overland @ 103,000 miles Began hearing a slight ticking noise under the hood for a month or so. Today had the P0304 (cylinder 4 misfire) error code. From what I can read, it looks like this is common on theses engines and is often times the rocker arms getting worn out (starting...

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...

Hi all, So I am rebuilding my 02 WJ 4.0. I bought new cam bearings, due to scoring them when pulling the cam. :frown2: My current understanding; The #1 bearing has a oil channel that appears to feed oil to the thrust plate. I learned older 4.0 had a thrust spring that pushed the cam back...

Hi folks, I had my 4.0l straight six stroked to 4.6l. Now I am wondering wether I could gain some more torque, espacially in low revs, by using another cam shaft. Does anyone have a recommendation on this? regards Brummi

Hello, I purchased a 2000 Jeep XJ 4.0L last week, it has 160,000mi. I bought it with the check engine light on, miss fire on cylinder two. Ignition Coil Rail, Spark Plugs & Injector replaced. Still miss firing, I found a TSB on this for the valves to become sticky from carbon causing misfires...

I'm hoping someone can give me a little insight into reasons for a cam gear failure when the old distributor gear doesn't look all that bad. I recently picked up this 79 CJ7 through a small car lot that was selling it as sort of a favor to friend of a friend kind of thing so I don't have any...

I have a 96 Cherokee country. 4.0 straight 6. Automatic. The beginning of this year I enjoyed that stalling out issues of the crankshaft sensor, until I replaced it, along with the distributor and a new fuel filter. I had the transmission rebuilt also and a couple weeks ago replaced a freeze...

So my jeep was misfiring badl at 3000+ rpms, replaced my distributor cam/crank sensors. Took apart the front end to check timing chain it was fine, took a scope into the cam gears they weren't abnormally worn...so I was completely stumped, took it to a local shop here and they told me the...

2005 TJ (2.4 litre) with major oil leak - Originally thought it was coming from crank seal, but on further inspection, it's running out from upper timing belt cover. I'm assuming cam-shaft seal(s). Has anyone attempted this repair? If so, any pointers? If it's not the cam seal, any other...

I drive a 93 cherokee country, 4.0 I6, AT, ~130k. This is a daily driver. Starts great, performs well for about the first 20 minutes of any drive. Then the engine will either bump, momentarily, stall then recover, or stall completely without any electronic loss or reset. The bumps and momentary...

I've read a lot of stuff about clicky/tappy lifters and rockers in wranglers. I pulled them out of my 2.5L to take a look at them because i recently had a big clicking noise appear. The lifters are a just starting to get concave, so ... new lifters and camshaft soon. (I could actually look down...

This coming weekend, I'm installing a completely rebuilt '98, 4.0L head (with Port/Polish) on my '87 4.2L block (no idea how many miles are on this since it was a replacement for the original 4.2L in my '91 YJ). I've done everything by the book thus far (new everything for the head, exhaust...

I have an 89 YJ 4.2 6cyl. I have been reading a lot on here about replacing the stock 4.2 carb with a Weber 2 barrel, however there is not much about aftermarket intakes except maybe putting a 4.0 intake on my 4.2. My question is do y'all think it would be better to go with an aftermarket Weber...
