Hi Randy, * * The correct numbers for your wagon's Fram oil filters:http://www.billhughes.com/temp/87WagFilter.jpg * * * * God Bless America, Bill O|||||||O * * * * mailto:BillHug...

In the course of changing oil on my 1987 Grand Wagoneer, I discovered that I could not get the new proper oil filter to thread onto the mount. *After a dozen attempts and a meteoric rise in blood pressure, I gave up. *After cogitating on it, I looked at the OLD filter, a POS FRAM filter, and called the parts house for a cross-check of the filter number. *The OLD filter was the wrong filter for an AMC 360. But now it's the only one that will thread on. Apparently, I will now need to replace the oil filter mount, insofar as the threads must be stripped to accommodate the wrong filter specification, but have not done this before on any of my Wagoneer, and so: *How difficult is it, and how difficult will it be to find the correct part? *Is there any other way of doing this, i.e., re-die the threads, etc. All advice will be appreciated. |
new PH25 temporarily until I can get the filter mount threaded part
that will enable me to restore back to the proper filter spec.

100% stock huh? *I understand your point/reservation if that FRAM oil filter was not for any Jeep 360 engine, I thought it was. *sorry. My '79 and '82 Jeep Wagoneer 360 engines used the same large size oil filter while my '88 used a small one stock for a different thread pitch like my XJ. I preferred using the larger ones but I did not change the oil filter pipe fitting. *I think you can find some larger oil filters if you wish to use them. There seems to be basically 3 different types of oil filters depending on the year. 1966-1983 *AC PF24) 1981-1986 *(AC PF46) 1987-1990 *(AC PF970C) I have NO idea what was on the 1991 360 engine. I usually find that some auto parts places lists parts that just aren't correct for my Jeeps, like air filters, oil filters, U-Joints, etc. I have to use what fits and what Jeep put on it. *;-) Good luck with your new ride! *;-) -- later, dave AKA vwdoc1 "DougW" <I.only.read.use...

different part numbers, coupled with the tendancy to move away from
the stock and OEM parts. I learned through this fiasco about the
thread coding on the filter, and a lot more than I ever knew there was
to know about the differences in thread specifications.
I am going to take down the AC Delco number for the 87 AMC360 and
hopefully by the end of the day, be able to fit that one.

to fit this filter. How best to tell, given that there are no records
to indicate that this was done? I have VIN No. but no engine number.
Thanks!

The more I think about your theory of an older-model engine, the more
it makes sense. However, in the course of looking into this, I have
discovered that the only year for which the particular filter was
specified, was 1982. How likely do you think it is that a 1982
vintage AMC360 would have been put into a 1987? One clue to the
necessity of an engine change is that the only adverse data on the
CARFAX report was an engine compartment fire back in 1998.
Is there the possibility that a particular long-block (i.e. a 1982
model) replacement AMC 360 would have required this smaller oil filter
in order to provide clearance from the engine mount?
Another clue: At first I was suspicious that some IDIOT had simply
installed the wrong filter, forcing it on, but after investigating, I
doubt that, because, 1. Any year but 1986 and '87 is an SAE thread,
whereas the '86 and '87 are metric, and; 2. The so-called "incorrect"
filter that I ultimately installed went on smoothly and tightened
normally and does not leak--something I would not have expected had
the threaded mount tube been stripped while forcing the "wrong" filter
on.
Any additional thoughts on this will be very greatly appreciated.

Hi Randal, * * You may at least verifier the engine's cubic inches, by a look atthe drivers side motor mount, like this 401:http://www.billhughes.com/temp/AMCengineblock401dsside.jpgIt could be a 304 instead of your 360. * * * * God Bless America, Bill O|||||||O * * * * mailto:BillHug...

number on the block on the left-side either in front of or behind the
engine mount. I do not know what this means.
