Anyone got a write-up on a 4.0? I need to either replace a head gasket or a head.

I've got a Haynes manual for a Cherokee. I am sure it would be the same for any 4.0. You can borrow it if you like. If you can get a Chilton's manual, they are a lot better than the Haynes.

Thanks, but I have a FSM for it. Just wanting to hear from those who have done it and may have some tips to make the job easier.

I,ve rebuilt a 4.0 for a comanche I used to have, Shouldnt be too hard of a job. Could be done in a day. I have a felpro Head gasket and valve cover gasket I would sell cheap if ya need them.

Save them for me and PM me a price including shipping. I will know what I need once I get into it, but either way, if I tear into it I will need those if they will fit.

tom, i have done a few. if you do it by your self, its easier to remove the intake and exhaust, all brackets and then head. if you have strong help i have left the intake and exhaust on and removed the whole assymble. it is harder and very heavy but was able to change head gasket in bout 4 hours from start to leaving for a trail ride. it ain't bad. good luck and have fun.

Thanks for the info. I am not sure what bolts to pull. Looks like the power steering pump and alternator are attached to the head. Looks to me like the intake and exhaust manifolds will have to be removed too. In case it is not just a gasket, I will have to take teh head off and take it to be magnafluxed for a test for cracks.
Tom, when you pull a head, you never know what you are getting into until you pull the head and have a professional machine shop take a look see at it. Sometimes the intake or exhaust manifold bolts will break or strip out, sometimes there are valves that need attention, etc.,. Just keep this in mind and don't pull head thinking you will put it back together in one day as it may or may not work out as you plan. Once you pull head, you want to take care of whatever issues there are as there is no point in replacing a head gasket just to drop a valve a week later. :eek: You will want to clean & inspect the head bolts carefully, I did a head on a vehicle that had already had head gasket replaced and blown again. Upon close inspection, I found a crack in a head bolt, that was the bolt removed from the exact location gasket had blown..... Head bolts were a Dealer item only and took a week to get a set and they weren't cheap, but that vehicle never blew another head gasket that I know of.

Don is right. I would find a 4.0 head and have it reworked before I ever started. Then you looking at just a swap and that can be done in a day.

Check with autozone. I am pretty sure you can exchange your head in on a rebuilt one. A friend of mine went that route.

WHY do they put bolts so you can not get to them!!!! What a pain!!!! The lower bolts for the intake/exhaust manifold are almost impossible to get to. I have to drop the exhaust, and the 3 bolts that connect the exhaust pipe to the cat converter are off-sized, siezed, stripped, and will take an air chissel to cut off! I still don't have the dang head off yet!!! This is no fun!
The only good news is I talked with 2 good mechanics that know the engine and they think it is just the head gasket. I will still have the head magnafluxed ($12) and milled ($48 and recommended when replacing the head gasket). If that is all I have to invest in this project then I guess the frustration will be worth it vursus buying a rebuilt head at around $400.
More to come....And NO, I am not taking any darn pictures (I would probably just get more frustrated and throw the camera and break it!).

Hey don, I sorted through my gaskets and I have the head gasket your looking for, but the valve cover gasket and intake/exhaust gasket I have is for the older HO.
The part number on the head gasket is 9076 PT-1 (felpro).
Sounds like your having a hard enough time with this project as it is, so I'll just go ahead and give ya the gasket free, I'll never use it anyway. Let me know when ya want to pick it up.

This is actualy for me, Tom, but I thank you for offering it for free!!!! I can get it Mon or Tue. Denise can meet you to pick it up. I still need the intake/exhust manifold gaskets, but those are only about $14 from Autozone.
Just PM me when you are available for us to get them, or you can drop it off at Yankeetown Elementary School for Denise, Or we can arrange to pick it up at your home if you give us directions and just set it outside.
Thanks so much! We are strapped with finances adn this helps us out a lot!!!

Exactly right. A blown head gasket usually is more of just a symptom of something wrong than being the actual problem.

Hey Vern, we haven't talked in a while. It is going slow. I am back to work now, a lot from home, and that has kept me busy.
I had to buy an air chissel to take off the exhuast bolts just before the Cat. I am hoping today to get the last 3 bolts off the exhuast and intake manifolds, remove the head, remove the rocker arms from the head, then take it in to be magnafluxed. If the head has no cracks, they will mill it, then I am ready to reinstall. More of a project than I thought it would be, especially out in the cold! When it is all said and done and assuming the head is OK, it will be about a $150 job instead of a $700 job by doing it myself. Guess that is worth a few skinned knuckles ;)

I dont understand why so many of you are obsesed with pictures, itnt it enough of a PITA to change a head gasket, and now he has to take pictures too? Seriously have none of you seen a picture of an engine without a head before? They pretty much all look the same! Just my 2 cents, go ahead and ridicule me now.

How many times have we seen a broken axle shaft? They all look alike.
How many times have we seen a lot of the stuff we see pics of?
Really doesn't matter as the rule is; no pics = it didn't happen.

Still unknown. I will take the head in Monday to get it magnafluxed. Not sure if the head gasket has a crack in it, but for $14, it will be money well-spent to get it magnafluxed. Don't want to have to do this again!!!
The antifreeze you see in the cylinders is what poured out of the head upon removal. I soaked it out with some rags and coated the cylinders with WD40 to prevent rust and pitting.
Once I get the head back MON or TUE, the fun starts in putting it all back together and hoping it runs with no problems - let's just hope the head is OK!!
Hmmm, now, about all those spare parts and bolts...are they REALLY NEEDED? :p

Agreed, no time like the present. I will drain the rest of the oil, get a couple of filters, put regular oil in along with 1 quart of transmission fluid, heat it up, drain it again, swap filters, repeat, refill with regular oil, run it just a short time, then go back with another filter and synthethic. Transmission fluid is a great cleaning detergent.

OK, I can not find the pattern to tighten the head bolts in the FSM!!!! I found they should be 100 Fbs but not the order to tighten them. Don suggested to just start at around 35 FSM (foot lbs) and work from the inside out, alternating sides, then go back to like 70 FBS, then the same pattern to get to the final 100 FBS. So 3 stages of tightening. Any other opinions are welcomed! Tom

Be careful with some of this information as he is doing a 4.0L head on a 258 cid. Even so, there is some good information here.
New set of Cylinder Head Bolts are $16.75 from Mopar Performance without any discount. (Part #: 4529204)
NOTE: Never reuse cylinder head bolts.
1. Coat stud bolt #11 with Loctite 592 sealant or equivalent.
2. Tighten all bolts to 22 ft/lbs following sequence.
3. Tighten all bolts to 45 ft/lbs following sequence.
4. Recheck all bolts at 45 ft/lbs following sequence.
5. Tighten all bolts to 110 ft/lbs, except #11 at 100 ft/lbs.
Torque Sequence http://www.monsterslayer.com/pages/jeep/40Head/40Head5.jpgFront
http://www.monsterslayer.com/pages/jeep/40Head/40Head6.jpg
NOTE: All the manuals recommend using this pattern.
Torque Rocker Arm Assemblies to 19 ft/lbs.
Torque Spark Plugs to 27 ft/lbs
Torque Valve Cover bolts to 70 in/lbs
16. What torque specification should I use on the Intake and Exhaust Manifold?
Torque the Intake/Exhaust Manifold to 23 ft/lbs.

Bolts 1, 10 and 11 are Studs with nuts.
Be sure to torque and retorque your exhaust manifold. A leaky exhaust manifold will cause the problems with O2 and the computer on the MPI Kit and may cause pinging. You’ll want to retorque your exhaust manifold after about 500 miles of driving.
NOTE: The factory manifold cup washers for a 4.0 are larger that those of a 4.2 setup. The larger cupped washers may be required in some installations to bridge your new manifold combination.
good luck torqueing some of those intake/exhaust manifold bolts! I just did them by feel. LOL

UPDATE: Well, the Jeep runs, but has an exhuast manifold leak (you can hear it and it is blowing sparks of burnt carbon our the top of the manifold).
There is no way to get a socket and torque wrench on the bolts that I know of. I used a boxed-end-to-boxed-end wrench and hammered on it with my hand to tighten the bolts. The lower bolts on the manifold could need tightening more (could be blowing the burned carbon deposits and deflecting them upwards), but what sucks is the hard-to-install exhaust popes on the manifolds would need to come back off in order to tighten those bolts more :(
I just seem to not be able to win with this project!!!! Any ideas welcomed!

I had to change an exhaust manifold gasket on a comanche once, and I was able to get a torque wrench on it with an extension, but I dont remember how long it was though. It was very tight quarters and it seemed to take forever to get them torqued, but it never leaked. Yours probably has a couple cats built into the manifold that will prevent you from doing this though.
Good to hear it runs again though!!!

OK, I know this thread is getting old, but I wanted to offer an update...
After all the weather delays, my uncle and I got the exhaust and intake manifold on this time without leaks. Now the rest should be easy right? WRONG!!!!
Got the exhaust on the manifolds, but getting the resto of the exhuast onto the part that connects to the CAT and back is impossible!!!! The bolts are frozen (cut them off with an air chisel), decided we need it off all the way to drill them out so dropped the transfer case skid, one bolt on the muffler spun on the pressed in bolt!!!
We need a torch to clear this up!!!!
I am calling a muffler shop tomorrow to see what they would charge to just cut the bolts off.
I am so close to driving it again!!!! Frustrating!!!!!

OK folks, after reinstalling the head, still seeing some antifreeze in the head under the valve cover, my neighbor put a pressure tester on the radiator with the valve cover off. The head definately has a leak and I can't find a replacement at the salvage yard. I had the head magnafluxed and it did not catch the leak!!!! It clearly is leaking from the inner wall beside the rocker arm assembly perch between cylinders 4 and 5. Anyone have one?

The head definately has a leak and I can't find a replacement at the salvage yard. I had the head magnafluxed and it did not catch the leak!!!!

I don't have a head for you Tom. However, you need to find a new Machine Shop.

Don, give me yours, you don't ever wheel your Jeep anyways! :p
there are many jeeps a liberty pull-apart, I don't know if that's a worthwhile pursuit, but just a thought... the price list says they are 25 bucks...

Whatever you buy, get it magnafluxed... this advice didn't work last time, but I sure wouldn't skip this important step.

At this point I'd just buy a refurbished head with a warantee
do the autozone heads come as a assembly? or just heads?

Liberty has 2 biz's one where they keep a warehouse, and one where they keep a yard, I don't know what years work for you but they have many xj's and zj, etc with the 4.0 sitting there... I only know because I get ALOT of axle shafts there (Dang d30!)....
