RSX Oil Filters - Exposed

[Gary Allan]

Well, I don't see how anyone can truly be disappointed with it. It's doing exactly as it's designed to do ...allow (by design) oil to go unfiltered. This is superb construction compared to the Ecore ..yet appears to have no filtering (at least assured) in the minds of those who designed it.


They did a bang up job in manufacturing ..and obviously have some issues in the design/engineering dept.

Correct me if I'm wrong, but aren't the following oil filters made by Champion Labs?

1. Bosch
2. Car and Driver
3. Deutsch
4. Mobil 1
5. STP
6. SuperTech

If so, do all these oil filters suffer from the same problem as the Champion filters (uneven distribution of pleats)?

 

[Gary Allan]

Well, I can say that most of the Supertech's that I've pulled apart, the media is spaced out a little at the adhesive point where they join it. I've never had a breached media in any one that I've opened and the rest of the pleat distribution was fine.

Upon closer inspection of the HAMP pictures, I'm wondering if the ends of the media aren't a fold? Don't know if that would solve the problem entirely.

Correct me if I'm wrong here ..but those pleats, although nice an uniform, appear to have open ends exposed past the glued seal.

Looking at that picture, it looks to me like the end-spring, for want of a better name, fits snugly in the end of the material and from the indentation on the endcap, holds the endcap material against the pleats, allowing no open path for unfiltered oil. I would expect some similar arrangement on the other end, just like the filter guy was trying to describe with the ecore's, but not very well. So do you think you've made hasty condemnations here?

Well, look outside the "ring" of felt. Those are edges of pleats. They traverse the entire media. The gaps outside the ring (the folds) are our view of the exterior and interior of the media. If we can view the interior ..or a pathway to it from outside the ring ..so can oil.

Unless we accept that the interior glue seam that's in view there ..effectively mates all the interior convolutions together ..siameseing them ..

This would effectively render most of the media a waste of material since oil could only enter the interior through a very limited area (the interior, mated, corners of the pleats.

Otherwise ..this thing is wide open to circumventing the media.

Suppose the pleats are glued together at the inner end. In that case no oil can get through the gap. I am assuming that the path to oil is into the center area with the silver jobbydo (too technical for you?)?

Do you mean the "bottom/top edge" of the pleats? If not that I think this:

said just that.

Zactly! If that's the case ....

That is, IF the interior portion of the media is all that allows oil to penatrate to the center core ...then why in the eff would you bother configuring all those elaborate pleats? You would just wrap a very small piece of media around the center tube and be done with it.

Since that would just pretty dumb ..we can feel assured that the folds are supposed to allow a much larger span of media fit into a confined space. The oil is supposed to travel from the outside to the interior over every square inch of it.

But the image that is in my last post ..makes it look more like a baffle than a filter.

 

[Gary Allan]

You have no idea how long it took me to find this image

Note how the compound covers the entire base of the pleats. This is the only way that I can figure that any of them could work. Sure you can cover the entire base/cross-section with felt ..but it too must cover the entire base. Otherwise you're just pi$$ing in the wind if you're trying to filter oil.

Let’s just make this simple, looks like the HAMP folks and the “ECORE” designer both must have a cousin that sells felt material, and they both failed filter school…at least filter basics 101 anyway. They seem to be spending a dollar for a dime’s worth of technology….looks all high tech and all but delivers “0” performance and is difficult to guarantee correct production quality specs. They both look like they are trying to “bottom dollar” the market. A standard filter is just not that hard to make….this is just extreme cost cutting…and good for us that BITOG’rs like to cut up filters!

While I was typing this Gary just added that picture above...that one looks pretty good! That designer must have passed his filter classes..

Did pee-wee try to further disassemble the filter media on the HAMP to see if the ends were bonded together internally?

 

[pee-wee]

The felt on both ends of the filter are essentially what held the filter together. The bottom metal ring that mated with the ADBV was glued to the matal core, but was easily popped off during disection. The PRV at the top of the filter sat on top in similar fasion to the Fram PRV. I must admit, this PRV was very nice.

My crystal ball tells me once the word gets out on the HAMPs, you'll see a bunch on EBay.

I've often wondered how many just lurk here for the intel on certain stuff. I mean ..stuff just spreads out of this site like some advanced social disease

Gary,

What kind of filter is shown in the photo that has the cardboard endcaps. (worldpack) It looks nice.

 

[Gary Allan]

Winston, that is a Mann filter ..I believe the image is from an MB parts site. This is what I thought an Ecore was supposed to look like in its conceptual discription (when announced). It would basically use a molded polymer for end caps, making the entire interior composite.

Maybe someone at Champion forgot to plug in the molded polymer machine?

 

[Winston]

Too bad you can't get Mann filters for Japanese cars.

 

[ZR2RANDO]

Winston, That looks more like glue, or foamy sealer that the element was pressed down in. It does look pretty good doesn't it? I wonder who makes it too.

Since my son has a new Honda, I've been doing some research on Honda filters.

It appears the good folks in Japan also know how to make cheap filters and have them marketed as the next best thing to sliced bread (HAMP). They send some over here and make them hard to get. Talk about special media and sell them for a few bucks more that the blue Honda filter. Bottom line is, they are made from all recycled materials and in Japan it's their discount filter.

If you want to cut open a well built expensive filter, get a Mugen filter for the Honda. But be prepared to pay through the nose. Last I checked, they were $27.00 each.
