2000 Jeep Wrangler 4.0 - Need Cyl Head by elbbirp
Jul 01, 2009 (7:37 pm)

This may be too basic of a question for this forum, but I'm in the process of replacing a cracked cylinder head, and decided to remove the oil pan first and check some bearings to see if they have been damaged by running with coolant in the oil. On my 2000 the exhaust wraps around the rear shallow part of the oil pan, so I proceeded to take the exhaust pipe connections loose from the exhaust manifold. This is where I'm stuck. I'm by no means a mechanic, but turned quite a few wrenches in my younger days, but it has been awhile. The exhaust pipe flanges are held on with 2 bolts that thread into 2 nuts on the back side of the flange. The nuts are some sort of flange nuts with a plate welded to the nut. The plate contacts the exhaust manifold when you turn the bolt, holding the nut stationary in order to remove the bolt. The problem I'm having is that after getting the bolts loose, the nut can ride up to a spot where the plate is free of the exhaust manifold, and turns freely when you try to loosen the bolt further. The spot welds on the nut prevent getting any sort of good bite on the nut with a wrench. Has anyone had the same problem? Do you have any secrets to disassembly, other than cutting torch?
Thanks.

I trust your word on these kinds of things and if you think a reman unit will work for my needs, then I'll trust it.
 
Ah, you're trying to put me on the spot!
 
1: Any of the choices even a standard TJ unit, if properly built, will give responsive steering with no central dead spot
2: For a small improvement in performance and minimal cost the reman Dakota SP box is probably the best short term value.
3: The PSC would be my choice because it's overbuilt for a standard or minimally modified Jeep, and I'll be keeping mine forever.
 
However, my choices may not be the best for you, and it would also be possible to get a perfect reman from Advance and bad unit from PSC (and vice versa), so there's no perfect solution..
 
If you have five minutes to spare take a look at this AMG promo to see the kind of loads and stresses the PSC box is expected to withstand.

I don't remember having that problem but can't you either push or pull the nut/flange assembly back down to the point where the flange will catch again and allow you to continue undoing the bolt?
Alternatively, is it possible to jamb the nut with a screwdriver/chisel/small rodent?
Just about anything would work as long as it's not your finger.
Final option is to cut the bolts and spring for a pair of new ones. You should be able to salvage the nuts after removal.
 
Have fun removing the pan, it's a fiddly job. It'll be easier if you raise the engine by releasing the mounts and inserting a couple of small wood blocks to support it.

Not trying to put you on the spot. Your posts show you know your stuff.
 
Any more information on the Dakota SP box? Define short term value.
 
I plan to keep this thing for a while longer, even with the mileage it currently has.
 
Any plans to get rid of your H1? Would love to see more pics of it. My wife is still wanting one of those originals. She wants to run over people.

I think heavier duty and different valving than the standard Durango box. However, do bear in mind that when you read a post about how someone replaced their original box with a Durango one and it gave a fantastic improvement, that's usually because the original box was knackered and an OE replacement would probably have given the same result.
You often see similar posts relating to spark plugs, air filters, brake pads etc. Replace a worn out original with almost anything new and you'll see the same result.
 
In regard to short term value I was just comparing it in price and anticipated longevity to the PSC unit.
 
I plan to keep the H1 as long as the Jeep, i.e. until I'm too feeble to maintain and drive it any more.
 
Here's a pic after playing in some Florida mud.

You, sir, SUCK!
 
Looks like fun.
 
I went and looked at my linkages which I KNEW to be good, but checked anyway. I found something. My driver side tie rod end was WAY loose. Cotter pin was still there, so I'm thinking I never tightened it down completely. D'OH!!!
 
I tightened it down well, repinned it and am currently driving it. In the process I re-centered the steering wheel too. Had a fellow Jeep owner drive it and get his impressions (without me saying anything - just asked opinion of steering), and he said it drives just like his. I think I'll hold off on my steering box replacement and keep kicking myself for not checking the links sooner.

Oh it is, though not so much the next day when you have to clean it.

Well, rather than kick yourself maybe you need to re-evaluate the way you check the steering joints.
By far the easiest is to have a helper smoothly rotate the steering wheel half a turn from side to side (with the engine running, parking brake on, and the vehicle on a hard surface), while you lay at the front and study each joint through the full range of movement. Any wear or loosness will be very evident.
 
Also, you might want to check to see if you've over adjusted the steering box in your previous effort to eliminate the play that turned out to be the loose joint.

Yeah, cleaning isn't so much fun, but it does give you time to look things over.
 
Your method for checking linkages is exactly how I did it this weekend to find the problem. I THOUGHT I did that before, but apparently I missed something. Believe me, a LONG, DETAILED mental note was made.
 
The adjustments I made on the steering box were done before I put the new tie rod on. It returns to center just like it should and there is no binding in the steering, so while the gears ARE wearing, the box seems to feel about right at this time. If it starts getting sloppy again, a steering linkage check will again occur, along with tightening any loose ones, recheck, then likely a new box.

My jeep is making this clatter, I belive its valve related, but before I tear into it want to see if its experanced by other...mainly at idle, and not the injectors , sure they make a click but not that type..
I have 94000 original miles, use good oil, all gets change on regular basis, carries about 44 lbs pressure at idle, no miss, no shake just sounds like a diesel engine..
