fiatslug87 Posted December 21, 2020 Share Posted December 21, 2020 OK, I was changing the oil and filter in my ’88 4.0L today, one would think the easiest thing to do, right? I had two WIX 51626 filters (was going to change the '89 also), both would not thread on, they seemed slightly big, I could feel the threads pass each other. I checked the IDs, ~0.735 for the old Fram PH3985 (I know, I know) and ~0.747 for the two WIX. I then went to NAPA, got a 1626 Gold series (made by WIX) same thing, so I got a cheap STP S3985 from Autozone, same thing too big, WTF?? The old Fram spins back on so nothing is wrong with the mount, my ’89 has a WIX 51626 and my ’90 has the NAPA Gold 1626. I guess its par for 2020. So now I'm in a holding pattern until I get one that fits. Anyone else have issues with oil filters lately? Link to comment Share on other sites More sharing options...
jdog Posted December 21, 2020 Share Posted December 21, 2020 is it possible that someone swapped to a later oil filter adapter? from what i see the later one uses a 3/4-16 filter, i had changed it on my cherokee and had the same issue with a loose filter, then realized it requires the 1085 napa filter Link to comment Share on other sites More sharing options...
fiatslug87 Posted December 21, 2020 Author Share Posted December 21, 2020 Don't the later ones use at torx attachment? This has a hex head and I've had it since 2006 and have never had this problem before, and the Fram PH3985 fits. Link to comment Share on other sites More sharing options...
jdog Posted December 21, 2020 Share Posted December 21, 2020 that was the same with me, the 3985 would fit, but nothing else would, can't remember if the bolt/torx interchange or not, its been a while.it might be worth a shot to try the other filter style just to see Link to comment Share on other sites More sharing options...
fiatslug87 Posted December 21, 2020 Author Share Posted December 21, 2020 Thanks, I'll try the 1085 tomorrow. I hope it's as "simple" as that. Link to comment Share on other sites More sharing options...

fiatslug87 Posted December 21, 2020 Author Share Posted December 21, 2020 jdog is the MAN! I owe you a few , that was it, still don't understand why the Fram 3985 fits but the STP 3985 does not. Now I need to find a Renix housing so I don't need two different filters. OK, I'm ready for that dancing banana! Link to comment Share on other sites More sharing options...

fiatslug87 Posted December 22, 2020 Author Share Posted December 22, 2020 And the reason people swap from Renix to HO threads is to use a larger filter??? Link to comment Share on other sites More sharing options...
jdog Posted December 22, 2020 Share Posted December 22, 2020 one of the reasons, other was i believe was filter availability. or p/o found and performed cruisers tips http://cruiser54.com/?p=257 Link to comment Share on other sites More sharing options...

Limited availabilty a pain for you? 20mm threads? We don’t need mumblemeter threads on our oil filters. Here’s a simple mod that allows you to use the very popular SAE threaded oil filters which are more readily available. The old standard 3/4″ SAE thread. You can purchase a new oil filter nipple from the dealer for under $10 and never be bothered again. Part number 53007563AB. It’s the one on the left. Or, grab one off a 91 and later XJ at the junkyard. Be forewarned though. You need a 7/8 wrench to remove a Renix nipple, but a 15/16 wrench for the later style. And just in case you need to replace your oil filter adapter o-rings, here’s a handy guide.

fiatslug87 Posted December 22, 2020 Author Share Posted December 22, 2020 Yes, I have three Renix MJs, two have Renix fittings, the other apparently an HO fitting, I'll just grab a Renix one from the JY. This way I don't need to remember which truck is not year matched, will only need to keep one filter type on hand and I've never had an issue with filter availability for the Renix filters.
