Canton oil filter in my 3.4 WOW!

[cgarr]

Well I thought this might solve my sump problem. For a long time my case would never empty of oil while driving, at idle it would take several minutes to empty the case into the tank so I could get a good oil level reading. Now while driving the case stays pretty much empty, after driving and at idle the gauge only rises a bit and its real quick. These filters are known for their high flow and with it filtering down to 8 micron cant be all bad either.

interesting never heard of them

I have been using Canton filters for years..my current iteration uses the canister style....(front mounted oil tank). I also use the fuel filters...

Have used for a long time. I like their cleaning power, but especially the fact that there is no bypass, unlike nearly all of the other filters available. This is made possible, I'm told, by the high flow rate.

Thank you for the link...I had to inquire more about this filter and their other products. They say it flows 15 GPM and no pressure loss...I wonder how many GPM my MAHLE filter has?

The "other than stock mounting" Cantons are supposed to be plumbed so the oil comes in through an end and goes out the threaded hole mid-way up the cannister.

I did this, and experienced an engine failure. I found that the extra pressure caused the fabric inside to tear. Luckily it did not tear through more than a few of its rolled up layers.

So I switched to putting the oil in through the side, the theory being that it woudl be harder to compress the pierced steel cartridge cages.

So far, though, I found one which was dented in at about where the oil entered. And some I have pulled apart after a routine change showed signs of the ends starting to pull out of their adhesive.

I am running a turbo pump in this motor, so there is a lot of flow.

Because my oil goes through another (stainless screen) filter before the front oil tank, and a final screen filter after the oil pump, none of this has caused any real issues, and crap hasn't gotten into my oil radiators.

What has been your experience?

But I just might buy one for the SC, since they make one for that application.

From the length of the filter in the picture it appears to be the 25-462 which is the 45gpm model.

Which model is that?

[cgarr]

Its the 25-412 with the 1"-12 thread.

The app chart I found listed the 3/4x16 thread as 911 which is definitely wrong. The calipers on an OC54 confirms the 1" thread.

Thanks for a quick correction.

[minoclan]

So for my 3.2 I should order the 25-412 ?

Yes, when I looked the company did not even show an application for the 3.2 but I found the number and they said, oh yea I guess we do have those. They do list them for the early cars but not the later.

Along these lines, check out Pure Power oil filters. They can be used in all vehicles including motorcycles, trucks, and even dragsters. They are made out of solid billet, have full flow filtering, have no bypass, use a superfine screen filter so have no paper element, and filter is cleanable. I've used this for years with no problems. If you hunt around on the site you will find technical articles and awards.

Their website is: Pure Power Oil Filters High Performance Motor Oil

I learned about these from Clewett. See:

Cordially,

Walt,

I have run these filters on my 914/6 race car for many years with no issues. One very important thing when screwing in the fitting that goes into the side of the filter housing for the remote mount models ... you have to grind off the end of the NPT threads that screw into the filter housing. If you don't, the fitting will protrude into the space between the filter housing and the metal cage of the filter element. This protrusion reduces flow since the space between the filter and housing is already tight.

FYI, I have always run mine with the inlet in the end of the filter housing. Note that if have the inlet on the side, I would think you'd risk having debris build up at that one spot in the filter and potentially restrict flow since in that configuration that would be the "easiest" place for oil to flow through the filter.

Craig,

Did Chris turn you on to this? Aside from the flow issue (which is of course very beneficial) his filter has proven to be a huge help in monitoring his engine after a rebuild due to a bearing failure. Makes it a snap for him to check the filter, vs. having to cut open a Mahle.

Thanks also for confirming the part no. and the thread size. I was going to copycat Chris and get one, but saw from Canton's part no. listing that ours was said to be "special" order. So I figured i'd wait or get a System 1. Probably will end up still waiting since we're planning to cook up some front mounted oil tanks for our cars this coming winter and that would make the use of the filter on the factory tank sort of short lived with only two events remaining after Gingerman before season's end.

Yes, well I didn't think there would be an benefit on our 911's but with the greater flow rate I think it does help after talking with Chris.

I have used the Canton on my 912 for years but its setup different. It filters the oil right before the mains not before it gets dumped back into the sump.

[euro911sc]

So the Canton is this one:

and the Pure Power looks to be this one:

Filters - Pure Power! Lifetime Oil Filter for Porsche (1971-1993) - PurePower!, Inc.


The Canton still requires a fabric/fiber screen to be replaced ($16.80+s/h for a single pack; $326 for a 24 pack) as far as I understand it. The PurePower one uses a stainless screen element. However the Pure Power is twice as expensive! The other difference I noticed is the Canton is 6" long where the PurePower is only 4" long. the PurePower also has magnets in it to capture ferrous particulates.

Economically, it looks like the PurePower is a better investment as you wont be dropping $16 each oil change. That's about 2-3 time a year for me so payback will be less than 5 years. Performance wise I'm not sure how they compare. I like not having to throw out stuff though.

Group buy anyone?

"my case would never empty of oil while driving, at idle it would take several minutes to empty the case into the tank"

I guess I am not understanding the problem that these things address...?

Using the side port as the "in" may be bad (as the manufacturer says), but about all I have seen (othr than the one denting of the outer cage) is that there are a few more little bits embedded in the fabric directly at the in port than elsewhere. And these seldom, if ever, are more than one layer deep, aren't dramatically different, etc.

You may be right that the pressure distribution against the fabric is better with the factory's end in method.

On the other hand, oil having to fight its way around the outside to get out might decrease the delta on the side farthest away from the side exit?

If I ever see some other reason to mess with this plumbing, I'll probably switch back to the way CM says it should be done. The tear in the fabric which led me to change orientation was only one or two layers deep.

Same here.

cgarr, did you have excessive smoke at idle after first start of the day or what was the issue?
