Hi,

I'm going to add a filter canister to my tractor. . . the one I've chosen is the orange can, black topped Fram from 50's chevys.
It used to take a Fram C4 cartridge (cotton waste) but now the big fat one in my Chev Van is named the C-4. Anyway . . . a fit will be available.

What I'm wondering is, is there a plug in the 134 block whereby I can return the filtered oil to the pan.

I've installed several and have run return lines to valve covers (but with pipe direction of the stream so it went right down a push rod to the lifter gallery and I did one or two with return to the pan -- but I would only do that again if the pan was off.

So maybe that's my answer . . . I have to take the pan off anyway. Those thick brass Weatherhead pipe connectors work really good as a locknut on the inside of the outside return fitting.

Thanks,
T

P.S.
I think bypass filtration is a huge factor in why the N's lasted so long.
 
i'm not exactly following all of your stuff.

the original cartridge style filter takes a napa 1004 filter element. it is not a floss filter.. it is poaper pleated. i believe that is a ch6pl fram, also not floww.. but pleated.

c159 is a floss filter that things like some allis's use.

Are you wanting to add a spin on adapter plate? if so it the plate, and oring and a new stem nut.

then it takes the stanfard spin on's like motorcraft fl1a,, napa 1452 or 1515, fram ph8A etc..
 
Sorry for the confusion.
Everything's fine with my spin on oil filter, but I want to also add a Bypass filtration system with hoses. I like the fact that they can filter down to 1 micron because there is no danger of starving the crank or shafts for oil, since the oil line TO the bypass filter comes off the block at the oil pressure sender point on the oil gallery.

So all I was asking was if there is any pipe plugs anywhere on this block that I could use for the oil return line to the crankcase.

On my 235 Chev there is a block plug just above the pan, where the filtered oil from my bypass filter on that motor is returned.

As I mentioned in the orig post, I have put these systems on a few vehicles where I returned the oil from the bypass canister to the engine by drilling a hole in the valve cover and putting the appropriate fittings in the new hole.

But I thought you might know of a pipe thread hole in the block (like on my 235) where the filtered oil could be returned to the sump.

Thanks,

hmm.. lotta work for something of marginal value on that farm tractor IMHO... especially a 62 year old one...
 
It's actually a pretty quick job when the oil return line route is simplified.
After those rims of mine, anything seems easy. :)

The oil in my Chev step van with a 1 Micron Fram cartridge has 15,000 on it's present oil and it looks like it just came out of the can. One of the elements that fits that canister is comprised of stacks of fiber disks and I use that in the winter.
In the summer I can put a cotton stuffed element in it, when there's less of a tendency to load up the element with condensation moisture.

When I took that fat canister into the Fram warehouse in Vancouver to find out what element it would take, the young guy at the counter said, "You're in luck, the old man is here today." So the old man comes out and his eyes light up when he sees the canister. He says, "this is the best filter Fram ever made, and it takes two types of elements." He was real pleased that I saw the value of it in the first place.

The one I'd use for the tractor, is the orange canister Fram one that was commonly U-bolted to the GM intake manifolds. This orange one still has that nice antique decal still intact.

Thanks again,
T

Edit:
I might have even come to the awareness of the value of bypass filters in the late 70's when I was an Amsoil dealer driving a '47 Chev flatdeck.
But Amsoil wanted an arm and a leg for their Bypass filter canister (mounting system) and filter and fittings so I said screw that and started buying a few old heavy canister filters from auto wreckers or wherever I found them almost free for the taking. So I've cleaned several of them up bought some oil hose and Weatherhead fittings and installed a few for people at a great price.

I see your point.
I may have made it sound as though I have some particular allegiance to Fram, but I was just recounting some history.

When first I went to our local auto wrecker and he said there was a box of old bypass canisters out back, the ones I was happiest to find still had their old cartridges in them, so the process of replacing that number or crossing it over to other brands was easy and I wasn't particularly concerned about the brand of cartridge. All bypass cartridges are able to filter down to smaller micron particles than full flow filters.

The canister I installed in my '51 step van just happens to take "the best cartridges Fram ever made", or used to -- which reminds me, I'd better try to order a couple while they still exist.

One of the few cannisters I have kicking around just happens to be a Fram from a 50's GM but I don't really care what i put in it . . . whatever fits.

But i'd certainly be interested in hearing what your favorite brands of cartridges are.

Thanks,
T

My Favorite is Wix, because they are readily available at my local independently owned auto parts store and also because they are highly rated on an independent test of filters that gets posted periodically on these forums. Fram on the other hand, rates poorly on that same series of tests. I have noticed that at wally world, even though I go there only about once a year, that they promote Fram.
 

Good to hear.
I had a good feeling about the Wix spin on that is on my tractor because it was noticably heavier than others. Our local auto guys deal in Wix and as it turns out, so does Amsoil. so on my last order, I ordered another Wix oil filter from them.

But for my hydraulic filter setup, there was no number in the Wix catalogue they sent with a previous order but they sent me the correct Donaldson Hydraulic spin-on (they bypass at a much lower psi).

I used to buy Amsoil DENSITE spin-ons until I found out they were made by Hastings and painted white by amsoil . . . then I started buying Hastings.

What you said about the poor showing that Fram makes in tests reminded me of a list of oils I used to have, relative to their rates of oxidation. Castrol GTX 20W50 was the worst oil on that list and yet by its heavy duty name you'd think it was the cat's meow -- kind of like the way WD-40 sounds like it must be serious stuff.

Thanks,

Might want to spend some time looking at filter specifications. Just looked up 2001 Chevy 5.3L engine oil filter and 1979 Ford F-150 and both show 21 micron filtering, however, the bypass "Canister filter mounted on the manifold" of old Chevy 235 I-6 element shows 32 micron filtering. Like many others seem to think, it looks like you are downgrading instead of upgrading.
 
Definitely more research is in order!

Here's an informative and funny video on how Fram sucks.
https://www.youtube.com/watch?v=XRRgw4B7R-I

Very good study of Spin-ons here:
http://www.austincc.edu/wkibbe/oilfilterstudy.htm

BEST study and specs I found:
http://www.evolutionm.net/forums/evo-engine-turbo-drivetrain/637158-official-oil-filter-testing-results-thread-4g63t-4b11t.html

The bypass element that Amsoil sold -- stacks of wood fiber disks -- they said filtered down to 1 micron. So I guess I jumped to conclusions about how small a particle the cotton waste elements, or any Bypass would filter.

I'm trying to find the Micron rating of the Fram C-21 cartridge that is now called the C-4. That's the one in my Step Van.

A comment about Wix filters:
"Glass-enhanced media in WIX oil filters offers greater efficiency, capturing more 10 to 12 micron sized particles than other cellulose/synthetic blend medias."

__________________________
There is no consistent relationship between micron rating and actual filtration efficiency. The relative porosity of a sheet of filter media is onlyone of the factors which determines the efficiency of a filter. The physical construction of the media, the filter and the element, as well as the types of contaminants to be encountered, are also very important. The entire filter
needs to be tested, not just the paper.
3. The micron rating does not show what happens to a filter over time. The performance of a liquid filter may deteriorate with use. The micron rating is a one-pass test done on a new sample of filter paper which provides no information about how a filter will stand up under continued use. The inadequacies of micron ratings have been readily apparent to the vast
majority of OEMs. Many have established their own rigid, repeatable, performance criteria which a filter must meet to qualify as acceptable for a particular vehicle. Others are calling for the standardized multi-pass test and its resultant
unit of measure, the B ratio.
To further simplify the specification of filters, SAE is currently moving toward adopting the multi-pass test as a standard procedure.
[b:8ee57f28f4]Unfortunately, reliance on micron ratings is still wide-spread at the user level.[/b:8ee57f28f4] Filter manufacturers reluctantly provide micron ratings to fleets who are still insistent on having this information, even though it serves more to confuse than to clarify. This situation will improve as end-users develop an appreciation for the tremendous usefulness of multi-pass test data.

But . . . . as you say, the WIX on my tractor is probably totally adequate so i should spare myself the extra work.:)

Just responding to your words. No comments of usefulness of rating or not.
