coolwind57 Posted October 24, 2017 Share Posted October 24, 2017 Was wanting to replace my oil filter nipple with the non-metric nipple today. Pulled the filter off to find a very long tube coming up from the old metric nipple. I did get the Mopar 3/4X 16 SAE nipple earlier, so I was expecting a like-looking metric nipple. Am I missing something here...should I be concerned about losing the elongated pipe nipple and going with the much shorter SAE nipple--especially since I plan on using the very-much-taller 6.93" WIX 51773 oil filter? Check that sucker out below. I'm off to buy a (very) deep well socket to get this sucker off now, I suppose. I think I read somewhere the old one is a 22mm.

HOrnbrod Posted October 24, 2017 Share Posted October 24, 2017 The adapter nipple replaces the existing pipe nipple. http://www.jeepforum.com/forum/f11/using-larger-oil-filter-renix-1124272/ EDIT: Renix question: The 91 and up HO filter "lays down" horizontally and points to the rear so there is always a quantity of oil left in the filter when shutdown. The Renix filter is straight up, so in the case of a filter w/o an anti-drain valve or a leaky one, all the oil would drain out causing dry startups. Not good, si?

Cool, I kinda assumed this was the case, but was a bit concerned about the length of the old pipe nipple and its functional relationship with my much taller WIX 51173 oil filter. You horizontal filter guys probably can't fit the 51173 filter can you? This sucker is massive! Just did my first oil change. To the fill mark, it took 7 quarts!

schardein Posted October 25, 2017 Share Posted October 25, 2017 Both my 91 XJ and MJ have filters that point straight up. I know this because I write the date/mileage on the bottom when I change my oil. And, since I have replaced my A/C system with 96 style hoses that use a different routing, now they interfere slightly with the filter, so I plan to lay them horizontal next oil change. Do we know if the change was a mid-year thing versus all HOs came that way? Link to comment Share on other sites More sharing options...

Just did my first oil change. To the fill mark, it took 7 quarts! The 6.93" filter size like the 51173 would fit but when changing the filter and sliding it off rearward it would come very close to the positive terminal on the starter. So I play it safe and have always used the 5.178" size like the Wix 51515. Link to comment Share on other sites More sharing options...
Minuit Posted October 25, 2017 Share Posted October 25, 2017 My 91 also points the filter to the sky. Will probably change that once I do the 96 AC conversion. Super convenient to change, worthless as far as filling it up goes. Link to comment Share on other sites More sharing options...

You're thinking that even as oil pressure begins as the engine starts, that the filter will not fill up completely? Link to comment Share on other sites More sharing options...
Minuit Posted October 25, 2017 Share Posted October 25, 2017 I like to pre-fill my filters if possible. The 4.0 in my '91 takes a couple of seconds to show oil pressure after a filter change. Link to comment Share on other sites More sharing options...
cruiser54 Posted October 27, 2017 Share Posted October 27, 2017 Works fine. Use Wix filters available at Napa and O'Reilly's. 1085 standard. 1515 extra CAPACITY. Link to comment Share on other sites More sharing options...
TheDude Posted October 28, 2017 Share Posted October 28, 2017 Best bet is to use a 7/8s wrench and use a pry bar against it. I'm a mechanic for a living and none of my sockets were long enough. Sent from my iPhone using Tapatalk Link to comment Share on other sites More sharing options...
coolwind57 Posted November 2, 2017 Author Share Posted November 2, 2017 I found a long 22mm impact socket that worked well. Definitely required a cheater bar. Link to comment Share on other sites More sharing options...
