Using a larger oil filter on a Renix

[1990JEEPXJ]

well as many renix owners know, there arent much in the way of oil filters out there. at least not the the extent that there are for the HO 4.0's. but there is a way to be able to use tons more oil filters, including the same ones HO 4.0's use. the reasons for doing this are more options for oil filters, and larger oil filters which is always a good thing. so i will go over how this is done, its very simple

here are the parts:
new filter- Purolator premium L30001, old filter, new adapter

first you obviously remove the old oil filter.

heres the adapter. any dealer stocks this part and it's around $7.

you will also need to remove the housing as well with a 16mm wrench

after you remove the housing, you will need to remove the threaded adapter inside the old housing and replace it with the new one.
but in order to remove the old adapter, which is a few inches long, you will need a crescent wrench to remove the old one, but chances are that it is stuck in there pretty good. so i had to cut off the unthreaded portion of it in order to get a 22mm socket on the adapter. i recommend wiping down the housing before you cut it.

once you cut that off you can remove the adapter with the wrench. you will need to use compressed air, brake cleaner or something to blow out the metal shavings in the housing. and after that you can install the new threaded adapter, either side works as they are both the same. i had to use a crescent wrench to tighten this one as i didnt have the right size socket. but be careful not to nick the sealing surface that the filter will be against.

this is also the perfect time to replace the housing o-rings, also a common dealer item.

after you replace the old o-rings you can install the housing and new larger filter.

and here is a list of what oil filters you can now use on your renix:

Nice write-up. Can I use the Amsoil EaO15 without changing to the new adaptor? Eventually, I'm going to install an oil by-pass system.
