For those of you who have searched long and hard on this forum for info regarding the o-rings on the oil filter adapter housing on your 87-91 XJ/MJ, here are the part numbers you need.
You can only get these from a dealer, and they do not come all three in a kit like the later model (92-newer) do. I am not positive of the year cutoff of when they switched, but if your oil filter adapter housing is held on by a 5/8" Hex bolt, then you'll need these o-rings.
Part # 33002970 is .80" and goes on the shaft
Part # 33002971 is 1.30" and seals the bolt to the housing
Part # 33002972 is 2.48" and seals the housing to the block
It will run you about $10 from the dealer.
I also mounted the housing so it is horizontal, like the later models are mounted. This is easy to do, all you have to do is make sure the filter/housing have the clearance needed. I had to move my charcoal filter, but that was it. I used just a little bit of permatex on the o-rings just to garantee a good seal when I bolted it back on the block.
I searched for this o-ring info and checked out lots of write-ups, but could not find it after an hour of digging. I found lots of info on this subject with my search, but it all pertained to the later model XJ/MJ's (94-newer). If you have any questions about this, don't hesitate to ask.
