SuperTech ST3593A Pictures

[AHC]

I cut open a ST filter used on my girlfriend's 98, 2.2L, Legacy. Looks ok to me except for the bypass valve/plate. Seems to be a flat plate over several holes (no rubber seal). I guess the oil is supposed to travel between the metal surfaces to reach the holes in the top of the element?

Picture of element and bypass plate.

the bypass looks like a boschs bypas.

So you can see the pictures? All I see are red Xs here at work.

Sorry. I saw the images when I previewed the post. How about this link...

ST Oil Filter

Yeah I don't like that style of bypass, some Bosch oil filters have ones like this.

Actually, I use this very filter, and still looks like good quality to me. Alot of people are wondering about this bypass 'clicker' valve, but has anyone seen if it actually fails, or does not work as well as the older style? Something like Bobs filter test?

i dont like this filter in my opinion. my car ran funnie and clicked all the time. and on top of all that, it was super hard to take off. but for the most part it is built better than fram.

I initially had my doubts about this type of bypass valve, but after rethinking the issue, I no longer do. Very few bypass valve types have what we would consider a "soft seal." All are usually metal to metal, plastic to metal, or hard phenolic resin to metal. All involve the oil pressure overcoming spring loaded metal. This "new" design by Champion labs incorporates all the attributes of other designs, just in a different way. It probably works no worse or better than those other designs (with the exception of Fram's plastic bypass valves--I'm sure it works BETTER than those).

Well, at least this filter has a bypass. I looked at an PZ-2 Pennzoil (FRAM) filter the other day and it didn't look like it had a bypass at all?!!!

I'll report back if I notice any out of the ordinary noises from the car at start-up.

Thanks for the responses!

I don't understand how the bypass valve works by looking at the pictures. Would someone explain it to me?

Mikey,

Look at the photo with the bypass valve sitting on the filter... When there filter is not stopped up there is no pressure pushing down on the center button, so it seals. When the filter starts clogging up, pressue pushes the button down, allowing oil to flow to the six holes and go down the center tube to the engine.

Hope this helps.

Dan,

I think I see. This bypass does not have a coil spring like I've seen in other photos. The end whith the 6 holes is deformed down to open the space to expose the 6 holes.

True?

Seem strange to me only looking at the photos. I guess that the end is springy like sheet metal because of the folds in it?

Correct?

 

[Dan4510]

Yes to both questions. I think you have it. Its sheet metal with a shape pressed in. when the center is pressed, it allows oil to flow through the center to the six holes and then to the center tube. And when the pressure quits, it pops back up and seals off.

The metal to metal will never seal absolutely. I have a sheet of specs for a fleetguard filter and it lists as part of the specs a small amount of oil that will continually run thru the bypass even when closed, but its such a little percentage of the total flow thru the filter that it doesnt matter.

Thx for the pics AHC. I've been worried about the possibly suspect quality of Wal-Mart SuperTech filters, but this looks pretty good!

Looks a heckuva lot better than the Fram equivalent posted here:

[labman]

It looks much the same inside as the ST 3590. Last one I cut open had 147 sq. in. filter area. Can you say how much the ST3593A has?

 

[GROUCHO MARX]

The 3950 is a bigger filter, no doubt about it.
