Changed OFA O ring

I changed the oil filter adapter O ring this weekend. Usually I can put a standard length wrench on almost any size bolt and break it free. You can imagine my surprise when I reached up with my right hand and gave my 12mm wrench hell (on the T-60 bit knocked out of the socket) and nothing happened. My shoulder/neck is still sore. From below is not the way to do this on a lifted XJ.

I welded that wrench to a length of steel and slipped a pipe over the steel. Broke the wrench.

Undeterred, I retrieved a 'better' wrench from my tool bag. I was able to put the wrench on the bit from above, and the offset in the wrench made it simple to get to. I slipped my high lift handle over the wrench and broke it free.

It backed out by hand after a few more turns with the wrench. The stock O ring was not broken but was very hard. Changed it and seems that no more leaky.

Moral of the story? This is easy to get to with a 12mm wrench that has some offset, the T-60 bit knocked out of its socket, and a cheater.

And once again, the most useful tool in the world:

Nice. I need to change mine again, it is leaking like crazy. Hopefully since I did this a few years ago it won't be as hard to get off this time.

I bought four O rings so I could change it again if needed. Did you change the inner rings on the bolt, or just the big one?

I changed them all about three or four years ago. The replacements must have not been the same quality as the originals, or I didn't get it torqued back correctly since it is leaking again. My rear main is leaking, oil filter adapter o-rings are leaking and the oil pan is leaking. I have been putting it off until the weather got better and I had the money to replace all of these and the header and exhaust. Hopefully in a few weeks I can get all this done.

that's where snapon and matco come in handy... much better quality than 'china' brand or craftsman...

I did all three a few years back too, they've held up well, but I need to do the VC and rear main now.

The craftsman has a little set screw holding the torx end to the socket body, so you can just pop it right out & back in no sweat. Comes in a kit though, that's hella expensive.
