the y-pipe bolts are horrible and don't cheap out on the gasket set. If you buy a cheaper set, i gurantee the lower intake gasket will leak, buy the better set. In my opinion with that many miles i would rather just buy a used motor. I replaced my wifes 94 4.0L for $400. You'll have close to that in a good head job, between gaskets and machine shop, and with that many miles on that 4.0L you can pretty much count on a cracked head or two. And after you seal up the top end and make it fresh again how's the lower end gonna handle it?

I did head gasket on my 93, had a bad valve on drivers side back cyl. and the center cyl. on pass side had a chunk of valve missing. I never had an overheating problem but both heads ended up being cracked and the cracks were not even in the combustion chambers of the bad cyl's.
Just my $.02

Have you done a compression check yet, or have you put a air hold fitting in the spark plug hole and see where the air is going? I am thinking with it missing that bad and only 1 cylinder not changing rpm when plug is pulled and no antifreeze smoking heavily out the exhaust it might not be a head gasket.
Stuck injector sounds like a good possibility. Possibly a cracked spark plug? Maybe worn camshaft or bent or broken pushrod/rockerarm? I just hate to see you pull a head and it not be the problem.

(but maybe i didnt notice it) so i am not forshure that that it didnt overheat i also see some oil on that side of the block looked to be coming from the head gasket.



this is a reason why i think that it is a head gasket and once i get the head off ill find out more as in if it has a whole in the piston or cracked rings or stuck valve
the way i see it i know the head gasket is bad soo i mine as well work on that and hope for the best

Watch for the bolts that hold the exhaust manifold to the head the like the top ones like to break off. Be sure to spend the money to have the head checked out and resurfaced at a machine shop, and unless you have soem seriously leaking valves do not do a valve job, that will save some stress on your rings.
