91coMANche

My trucks not getting any 97+ body parts because that would make it something it is not, a 97+. So do the older mirrors just screw in and do the plastic triangles pry off?

What year manual XJ front door regulators would work on my comanche?

Do the XJ mirrors just bolt in? Do the little black plastic triangles snap off where the mirrors should go?

I've seen cracked manifolds cause ticking but that usually goes away when the engine warms up.

Mine has a rubber gasket and then a frame that sits 3/4" to 1" outside the sheetmetal. I don't think its factory. It doesn't bother me but it doesn't seem factory.

Ah so that is factory. Mine is not factory. I guess I should find one before I get her painted soon. I'll be pulling the back window anyway.

My truck has a rear slider window but it sits outside the sheetmetal by about 3/4". I am not sure if it is factor or aftermarket. Does anyone have a picture of a factory rear window they wouldn't mind sharing with me?

Thank you for your service and keeping us safe :USAflag: I wish I could help you off the top of my head but I cannot. I have a 91 and when I get a chance I will look at the hoses and post back. I also have a Haynes manual that may describe how the later part you have installs. Come on guys, somebody has to be able to help out off the top of their head what direction the heater hoses go. :USAflag:

I want to take the mirrors that bolt to the sheetmetal off and install standard XJ mirrors that adjust from the outside. Thoughts? How about these? http://cgi.ebay.com/ebaymotors/84-94-JE ... 2971wt_995

I was totally wrong. I looked late at night :oops: and mistook the electronic speed output sensor as the slave cylinder. I in fact have an internal slave. My head says "91" on it so I assume the block and crank match along with the transmission. I will probably be getting a 97/98 engine and either buying or making a pilot bushing on a lathe.

I wish I still had the board but the previous owner took it all out when it started sagging. I wonder if I can still get factory board... I'll check out ebay for the SMS guy.

Yeah, the head is off and the number 2 piston is nasty. Number 2 is so scored it would take a decent overbore to fix. The rest are pretty scored. They are tough as nails so long as you don't drive it without water for an extended period. To his defense the previous owner didn't seem like an avid jeeper or even seem like he knew much about automobiles. The thought about the external slave just hit me so now I want to figure out what year my transmission is...frankly i'd love to know what year the engine is...the head didn't have 12 point bolt heads which means someones either been in there before...

It ran and revved but the previous owner only ran and revved it for a couple seconds because it had no water... When I put water in it to prepare to drive it home the actual problem showed its face. Thats when the hard starting and steam got crazy. The number 2 piston is destroyed and has around .125" of gap with the wall (piston can rock in the bore). Engine is toast - end of story. Now I am curious to find out what year my transmission is...perhaps its a later year...are they date coded?

I'll snap a picture and post it up but I am pretty sure I saw a long black plastic slave-cylinder hanging off the transmission. Would this fact change anything with my pilot bushing predicament? It could mean either the person put on later model bellhousing or later model transmission?

I need a headliner (nothing now).

Now I'm about to throw a wrench into the gears...if my 91 has an external slave cylinder then does that possibly mean that the transmission isn't a 1991 transmission? Is there a date stamp on the transmission or anything that I can check? I would be ecstatic if it turns out to be a 92+ AX-15. I guess I could also find a 92+ AX-15 with my replacement engine...

Thanks! And I assume what you meant in your last sentence was ....but using the one closer to the end of the crank should be fine." So If I use the bigger one I posted up what would be the downside? I have read of some people having trouble with mating the engine to the transmission when using the one I posted up. Would I just be able to take some material off of it with a grinder? I am really unclear on what role this bushing plays.

This is the pilot bushing that I am told to use: http://advanceadapters.com/product/2590/716120.html Will my stock intake and exhaust all line up with the 97/98 head ports? What about crank position sensor and such? Do I literally just thread in everything from the 1991 engine into the later 97/98 and just reuse those old sensors?

Thanks! So I found this on Dino Savva's site in regard to what I can do to put a newer engine to my 1991 AX-15: '89.5-'91 AX15: "OEM pilot bearing 33004041 for '87-'91 4.0 engine or stroker Advance Adapters pilot bushing 716120 for '92-'06 4.0 engine" Now I don't know anyone that has bought this Advanced Adapters pilot bushing but it seems like that is all I need to make it work.

Previous owner drove it without water and a blown headgasket for a good while. All 6 cylinders scored and likely bent rods from hydrolocking. Stock engine is getting pulled and none of the longblock will be recycled. Getting a complete replacement and then trying to bolt on my 1991 accessories, intake, and exhaust. Any idea if the engines I mentioned could be used?

The 91 I have is blown out (see other thread). I want to replace it with another 4.0. I can find lots of 4.0's newer than 1991. Other than the pilot bushing, will a later engine from a manual or automatic bolt into my 91 AX-15? Will the engine from say a 96-98 ZJ work? 97-98 TJ? 97-98 XJ? Does auto or manual matter? I want to keep using my 1991 fuel system and intake/exhaust manifold.

So my truck is a 1991. According to this page: http://www.jeep4.0performance.4mg.com/tech_specs.html if I get a 92+ 4.0 I need an advanced adapters pilot bearing to use with my 1991 AX-15. Is that correct? Here is the exact quote: "'89.5-'91 AX15: OEM pilot bearing 33004041 for '87-'91 4.0 engine or stroker Advance Adapters pilot bushing 716120 for '92-'06 4.0 engine" Is that right? There was a change that prevents stock parts from being run?

Head is fine!!! Piston is wobbly in cylinder and the previous owner obviously overheated it after the hole in the radiator and then hydrolocked it just driving it and topping it off with water and keeping it running while burning water up. The bottom end is toast. Need to do a replacement. BIG QUESTION: Will any 91-99 4.0 long block bolt in with my accessories and 2wd AX-15?

For sure not trying to cut corners on this AMC icon. I assume the factory gasket is 100% blown and I would assume the has issues. I may have a fresh head later today to bolt on but I'm not sure. Not having white oil gives me motivation but who knows what ill find. If I need to replace a motor I'm not sure whether I'd redo the stocker or get a used one. So any head gasket replacement tips?

ZJ front clip on an MJ? :huh???:
