Oil Filter Variance

#1

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.

Looks like it is just a threaded nipple. I'd take the thing off (takes a
deep socket), clean it up and have a look at what's wrong. You can often
clean up the threads without TOO much grief.

Ah, do you mean threaded into the mount? I have not been able to see
all the way down to the base of the filter thread, so was not aware of
that. If you can turn the filter thread out, then I could use a die
to rethread it--or replace just the threaded shaft, not the entire
mount. Many thanks!

The picture in the parts book shows a larger diameter threaded end that
fits the oil filter, a hex center, and a smaller diameter threaded end.
I don't do the V-8 AMC engines so this is from the book only. (Not that
I wouldn't mind owning a CJ-5 with a 360 and side pipes!!)

That's what I'm looking at, leading me to think that the threaded part
can be removed and replaced without having to replace the entire
filter mount. How hard that threaded center will be to find, I have
no idea.

USE WHAT FITS!!!
What is wrong with that? Don't fight the system unless you want that '87 to
be perfectly stock.
I have seen many oil filter listings that were WRONG especially for our
Jeeps!!!

Get a filter for a 1979 360 engine if the oil filter pipe threads are not
damaged.
I used Purolator filters and liked them although I did get one that had an
oversized fitting on it so it did not even thread on, it slipped over. It
was wrong!

Well, first of all, I DO want the Jeep to be completely 100 percent
stock, and second, the filter capacities are different. Third, as it
stands, the only filter I can get to fit on it is a FRAM filter, which
ordinarily I wouldn't in any case. However, on the positive side, the
parts illustration indicates that the threaded stem of the filter
mount can be removed, and therefore replaced, which will happen
tomorrow.

If you do a lot of towing or heavy off-roading they make an oil
cooler adapter. Google will pull up quite a few.

Hi Randy,
The correct numbers for your wagon's Fram oil filters:

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! ;-)
