Mine was a T60 which I could only get in a 1/2" drive socket. That wouldn't come close to fitting so I heated the socket and got the torx bit out of the socket. I then put it in the fastener and used a 1/2" wrench to turn it. Took about 3 minutes once I figured that out! YMMV if you wrecked the treads. Weld some bar stock to it, get it out and then weld a nut on it!!
Edit, yeah I looked at my socket and it's a T55!

 

I thought it was a T55 anyway. Mine is a 90 and that is what I used to get mine off. I went to the later style oil filter housing so I can use the larger filters.

 

If you cant get it off yet and still want to try something, like I mentioned above use the "right stuff" gasket maker/silicone. Its better then standard RTV since it has a paper base to it which makes it great for using as a gasket instead of a gasket.

 

I hate to see your problems as I had to do the same myself and just finished it... I looked for the o-ring to replace it but all I got in reply is that 'we don't offer that' or 'we have to order that part' What a waste of time! I decided to poke and prod around to find something to use and found the oil filter that came off of my friends s-10 4x4 when I helped him change it, and was surprised to find that it was almost perfect in size! It is still holding up great and didn't cost me a thing! I had the torx for it already from having to take the fender bolts out before... Yes, mine was the t-60 and I really have to say that they could have come up with a better amount of space for it but leave it to braniacs to replace a simple bolt!!! Anyway, good luck with it!

 

This bolt problem reminds me of the stupid inverted torx bolts that hold the bell housing to the motor on the top in back. I had to grind them off to swap motors, I of course put standard bolts back in place.

 

They used the same bolts to hold some of the transfer cases together also.... VERY AGRAVATING TO GET OUT!!! I had never dealt with them until I did my first t-case overhaul in my friends backyard, didn't count on those!

 

OK..Here`s my latest plan...I`m sure I`ll get a few warning posts about metal filings in the engine but I`m hoping since the adapter tilts downward and there will be a flow of oil that way and I`m using a very thin bladed hack that there should be no metal finding it`s way up stream thru the thick oil.

First step is to go to the local junkyard and obtain a new (used) filter adapter. I`d suggest getting one off a Grand Cherokee as they have easy access to these things..This is the adpater I got last weekend for $10:



Here is a view of the adapter with the big bolt removed:



Now here is my plan..I intend to cut across the adapter stuck on my Jeep about the point of the redline and only as far across as it goes:



As you can see from the following image cutting in this spot and only that far across will remove the thicker head of the bolt. Once this is cut the top of the bolt will just pull off and once that is off the adapter itself will simply pull off the engine block leaving a good portion of the bolt sticking out with the large hole in it. From that point it is simply a matter of putting another high grade bolt thru the hole in the adapter bolt and putting a pipe on it and turning it off or using a small pipe wrench on it..I would imagine without the adapter and it`s gaskets around it and the resistance of the bolt head the bolt will turn easier..In any event with the adapter itself gone I will have a lot of room to get at the remaining bolt.

 

Question, Have you tried to turn the whole unit itself? That may loosen the bolt, or you can turn that and the bolt at the same time. I would try that first.

Put a fatty screwdriver or chunk of solid bar in the hole where the oil filter screws in and pull down.

 

I don't think you'll be able to do that. The few that I have changed for customers ended up having a dowel in the aluminum part of the housing. That will effectively stop rotation.


My vote is to weld a nut to the end and just remove/replace it.

Yes that`s the case on mine...It`s like whoever designed it tried to think of all the ways you`d try to remove it and blocked them

 

Definitely impossible to turn the whole thing, they do have some type of dowel in them, I would guess so that it couldn't turn when it is not supposed to.

 

the adapter nut on my first xj had marks from a pipe wrench on it. I don't know how the PO did it. Must be possible some how.

 

All you really gotta do is go ask a guy who can weld to weld a nut to a bolt (or weld it urself). It will costs...what....$10-$20. Just tack the damn thing to the head and it's done. 5 minute fix. no headache, no waiting, no heavy thinking....

or if you are really good with a dremel in tight spots you can shave sides onto the head of the bolt to use a socket on it.

 

what helped me was I did my motor mounts at the same time. pop off your motor mount on that side and lift up your motor. it will give you plenty of room to work more efficiently. HTH

 

Thats weird, cause mine spins like a cheap set of rims, haha
