ADBV needed if filter is vertical?

Purolator's website look-up does not list an app for that Impreza.

But a Forrester with the same engine does. Go figure.

would you get the same amt of oil pressure with or without adbv?

Thanks for checking, but I believe none of these has the 23PSI bypass setting. It appears the OEM is the only one with both the ADBV and the 23PSI bypass.

Yes

After seeing the flow vs PSID data from Purolator on the PureONE, I really don't think a Purolator filter needs the 23 psi bypass setting. PureONEs usually have a 14 to 16 psi bypass setting. Maybe the OEM filter does for some reason (ie, more flow restrictive or maybe loads up faster and the PSID increases more due to loading).

FWIW, I have tried with my wall mounted filter holder to see of I could get oil to siphon out of a thread-up filter after I disabled the ADBV entirely with an Exacto knife.
I never could get the oil level much below the threads, even with extreme siphon situations.

In a later post I pointed out that once air made it into the top of the filter, the siphon would break.

As far as I'm concerned the filter orientation makes no difference. The siphon action of the oil doesn't care what the orientation is, only that there is some oil up high that wants to go down. The siphon continues until an air break stops it. I've watched oil drain through the filter media over a long period of time into an oil disposal container so it can do the same thing in an engine though it probably takes longer because it needs to draw against all the oil films.

My 1994 Grand Am 2.2L SOHC Quad 4 uses a side facing filter and apparently the drain back problem is so bad that GM added an oil check valve into the block.

There's something about engines that make them fast drainers but I don't think the filter orientation is it.

Agreed, however the topic is typically revolving around keeping the filter full ..which was never the primary function of the ADBV. That's not to say that some don't attempt to use this to their advantage. Vertical orientation assures that the filter will be pretty much full for the very reasons you state.

Yes. I think I quoted the wrong one. Sorry.
I was agreeing with you.
