The blue glow is a feature, not a bug

If you own an older Jeep, sooner or later you're going to have to replace your cracked exhaust manifold. I've been putting this off for awhile. Like years actually. I couldn't take the noise, the performance, or the lovely mileage so I broke down and bought the parts and did the fix a day ago because my mechanic quoted me 440 bucks for the fix and im unemployed and broke.

Its not a hard fix, just label all bolts, or take photos so you remember where everything goes, thats probably the most important thing. During the fix you have to remove your power steering pump, airbox, and intake manifold to get the exhaust manifold out. The hardest part is getting at the lower intake manifold bolts. A wobble extension worked great for this, and a set of Great Neck flex wrenches for everything else. All in all it took me about 4 hours and 8 beers.

First things noticed was how quiet the XJ is now. It no longer sounds like a lawnmower. Smoother idling, shifts better, my mileage is once again acceptable, and it sounds pretty good on acceleration to boot.

Here be the pics
Everything removed you can now take off the exhaust manifold/header unit. All bolts are 14mm for the manifold systems.


As you can see, I had a pretty bad crack. It was all the way around.


This is the new one. Its made by Rugged Ridge, and had a raw steel finish. I primed and painted it with high temp paint. The top has held up so far, but at the exhaust flange gasket the paints flaking off already. Here's the link to Quadratec. It comes with everything you need. I suggest buying that spray on copper gasket stuff though and spraying both sides of the gasket.


And everything back together.


Edit:

That is a beautiful XJ. Thankfully mine hasn't cracked its exhaust manifold yet. However my old XJ with its 2.5l had cracked its exhaust manifold twice.

I put swaybar disconnects on this weekend, and I was looking at them exclaiming "Why are they at such a goddamn terrible angle, THAT'S STUPID".

I put the studs on the axle end(bottom) backwards or outboards instead of inboards, amazing once I switched them around they were easy to connect and disconnect and not tight as gently caress, and at a stupid angle.

I blame hot shop and cold beer.

Everyone, say hi to Renix. Renix, say hi to everyone. :tipshat:



As mentioned previously, Renix has been waiting for a new gas tank and some fuel injectors for quite a while now. I think these pictures make it pretty obvious as to why:





So, I painted the gas tank:



Then, I put in the fuel injectors, and the gas tank:



And here's where poo poo gets lame. I forgot to take a picture of the installed gas tank, and upon taking a test drive I found that I had improperly installed one of my fuel injectors and it was spraying gas all over the intake (and exhaust!).

Next week I need to put a muffler on it, so that's when I'm going to take apart injectors again and see what I did wrong. I thought that I saw a piece of an injector sitting on the intake, but when i went to grab it, it fell with out hitting the ground, so I'll see what condition the #2 injector is in when I pull it apart. Hopefully that the issue and I can get it replaced by the company.

I'll give this a shot, it's mostly third hand information so it may be a total flop.

I've got a friend with an '03 Jeep Wrangler. The original I4 in it blew up so they put in a new one. That's where the problems started. Engine went in fine went to start it and the typical hard starting/bad idle/eventual dying of a mistimed engine. Retime it? Same thing. They used the old ECU so perhaps there's some sort of ECU reset that needs done? Any ideas or suggestions would be appreciated!

Have you tried disconnecting the battery completely and then turning the key? After you do this hook the battery back up and try starting it. If thats a no go, try pulling codes.

Just got a P0700 code on my 2003 WJ Limited. The barely noticeable difference is when I try moving the shifter, it's kinda harder to push. Though if I press the brake pedal a bit harder, nothing seems to be wrong when shifting from D into R and vice versa. Everything else seems to be fine. Is this a sign of impending doom for the transmission or what? Should I have the dealer look at this right now, or can it wait?

You'll need to have the TCM scanned.

quote:

P0700 (M)


Check Transmission DTC's


This code indicates that the EATX (Transmission controller) has an active fault and has illuminated the MIL via a BUS message. The specific fault must be acquired from the EATX via a DRBIII tool. (Input or Output Speed Sensor failures often cause this code and are a common failure part on WJ Grand Cherokees).

Jesus christ. Took my jeep in to a shop to have the steering pump replaced with a new one I've had laying around. Shop tells me the jeep is idling weird because of a "loose intake gasket." I ask them to tighten it down and replace the pump, apparently that's $650 worth of work?

While the intake bolts can be a certified pain in the rear end to get to, I don't see how they could have charged that much for labor.

I'm a masochist, so I thought I'd buy a second Jeep to supplement my '05 Rubicon.

It's a 1972 Commando C104 with a 258 and a 3-speed. I'm not familiar with these at all, but it seems to have a spring over lift to fit 30x9.5R15s. It has no power brakes, no power steering, no power windows, no power locks, and no power. I have yet to drive a vehicle that even remotely compares in fun factor. Forgive my lovely cellphone picture.

If your Jeep didn't come wired for a hardtop, you'll need to buy the correct wiring harness for the top; otherwise, the rear wiper and defroster are useless.

So I have a WJ, and recently I had an oil change dude tell me that my rear mail seal is juuuuust beginning to seep out just a tiny bit of oil. It wasn't enough to actualy "drip" and my engine still was 100% full of oil after about 4000 miles so it's in its infancy now.

I did want to ask you guys though, how long do these things usually take to get to the point where it needs replacing? My WJ is unique in that it actually has the 4.0L I6 engine that's so famous in Jeep circles and I seem to recall people mentioning this issue with older Cherokees. My WJ is pushing 95K miles right now.

Jeeps are self lubricating, ignore it. My WJ had a slight (but dripping) leak when I got it at 89k, it went away after about 15k, is at 140 now and still fine.

I have a 4.0 as well, with the same slight rear seal leak. I have yet to replace mine because of :effort:, but my understanding is that the rear seal is a two-piece seal that you can change just by removing the oil pan. I even found a guide with some pictures: http://www.jeepin.com/features/rearmain/

But yeah, you should only have to worry if something's not leaking. As long as it's leaking, it still has fluid.

$2,500 engine rebuild and a six month wait to get a good nickel-plated timing cover and oil filter adapter from Bulltear because your found the rear main bearings wiped to copper.

Seriously, be careful with the AMC v8. I love the engine, but if they've been running low oil pressure for long they'll eat the main bearings, starting from back to front. Oil pressure is often low because of several factors.

Number one is the oil pump cavity itself is made of aluminum. There are two gears that spin inside the cavity, transporting oil around the outside of the gears along the pump cavity face. That face gets scored up easily, being that it's made of aluminum. Once scored, oil pressure is lost.

Another source of lost oil pressure is the oil filter adapter. The gears also ride along the face of the oil filter adapter, it's also made of aluminum.

Another problem with the oiling system is again in the oil filter adapter. The filter adapter has a faulty oil filter bypass, which can allow poo poo into the oil pump, which scores the walls of the oil pump cavity.

The final problem is that the motor just doesn't oil the rear main bearings very well. Oil doesn't get back there.

First fix is a nickel-plated timing cover from bulltear.com. Oh, did I forget to mention the oil pump is cast into the timing cover? Ok well the oil pump cavity is cast into the timing cover. Anyway the guy is meticulous, but very slow. Expect to wait and wait and wait for your timing cover. There is only one manufacturer of timing covers these days and they're often poorly made. This guy at bulltear gets them, inspects them, corrects them if needed/possible and then nickel-plates them for durability.

Second fix is a nickel-plated oil filter adapter again from bulltear. You can order this together with a timing cover. I also highly suggest their "HRC" oil pump gears, they fix a problem with the oil pump gears that causes them to flex under load, which also causes scoring of the oil pump cavity.

The final problem can be remedied with a mod one can perform only during a rebuild. I've done it on my 401 during it's rebuild. It involves tapping two holes in the lifter vally and a line run from one to the other. This transports high pressure oil from the front of the engine to the rear.

Guhhhhh I think my eyes went crossed! It really is a love/hate/love relationship with old Jeeps isn't it? I'm guessing no "improvements" were made to any of these old V8 engines during Chrysler's (brief) stewardship of the Wagoneer?

Honestly it almost makes me want to pick up a restored Wagoneer second-hand from somewhere like Wagonmaster.com or somewhere similar. Seeing as how I'm moving to San Antonio, TX in a few months and Wagonmaster is located in nearby Kerrville, I guess that's not an impossible scenario. Some of those Wagoneers are even converted to have fuel injection.

Rear mains will always do this, like everyone's saying. Ive replaced one on a friends XJ, and its something id never want to do again (for free anyways). I have 155k on my XJ and it will drip once in awhile, but its nothing that concerns me. Also be sure that it is your rear main. Some times the valve cover will leak from the rear and drip down, giving the appearance of a rear main thats leaking.

Seriously though, its one of the biggest pains in the rear end to replace.

Sounds like a power steering pump or other hydraulic issue.

When you turn the wheel to full stop it triggers a bypass so your power steering pump doesn't lock up (I believe it's a positive displacement pump).

I generally avoid every turning the wheel to full stop and holding it unless it can't be helped. I turn it all the way then back off a smidge.

Or I could be retarded and full of poo poo. I haven't look at one in 10+ years.
