Changes to AC Delco PF-61

[Triple_Se7en]

I've purchased a few of these over the past 4 years. At the last moment before my purchase today, I decided to look inside for a stamping that said it was made in America.

Well I found the Made In USA stamp -- but uncovered an ADBV - which never before existed. So I did some peeking inside 11 different oil filter brand boxes at three auto part stores. The only two brands that do not house the ADBV are the STP S3675 and the Baldwin B7010.

The Mobil-1, AC Delco, Purolator Pure Ones, Purolator Premium Plus, Fram, K & N, Bosch, Wix, NAPA Gold - plus house brands from Pep Boys, Auto Zone and Advanced Auto all have the ADBV. The only place I failed to check was Wall Of China for their Supertechs.

I just thought I would pass this information out there in BITOG World.

I have the Supertech ST3675 E-Core in my hand. You can just barely see the ADBV. but it's in there. It also has that new flat plate at the thread end. Say's "Product of USA" (Pat. pending of course).

 

[Triple_Se7en]

I don't see any ADBV with the sister-STP. Idon't see any media either. It's all metallic inside with over a hundred small vents that have an opening on their bottom-side. I wonder how restrictive this will be/ Is yours the same?

I noticed the new PF-61 AC Delco with the ADBV have an Ecore black plastic cage.

 

[pmwalter]

Triple Se7en, My Supertech is the E-Core design. It has the black cage design. Your STP must be the older design. My Supertech is also very light. One of the lightest oil filters that I have ever held. Probably lighter than a FRAM 3675.

Interesting. I have always used PF61 on my '05 3.5L Colorado, as it seemed to be the only one without an ADBV. Now I have no idea WHY the lack of an ADBV would be a GOOD thing, but I figured that AC Delco is the OEM filter and maybe they had their reasons for leaving it off of this particular design. I think I still have one or two of the DELPHI-made PF61 filters on the shelf without the ADBV, but I have no real worries about the new filters with the ADBV.

ADBV may go faulty - may not go faulty.

I look at it this way...
Why use a part - when that part is not needed. The older AC Delco PF-61 kept your filter full of oil 24-7. Plus there's an oil channel above that filter that houses ALOT of oil.

I've got to check-out the Supertechs for my own birds-eye view. I am half-tempted to go out & purchase several of the STP filters -- before they change the design & add an ADBV to it. I would repurchase the Baldwins - but I hate paying $8 plus shipping for several oil filters.

All this concern about a filter having an anti-drain back valve (actually a piece of silicon or neopreme that you see under the outer holes on base plate) is much ado about NOTHING. If it fails, nothing will cause any engine damage. Reason for leaving them off of filters is to lessen the cost.

Nobody said anything about engine damage. Nobody said they were concerned. Not sure how you grasp your reading material - but in this case - you are wrong in your assumption.

Manufacturers DO NOT leave ADBVs off filters -- WHERE THEY ARE ASKED TO PROVIDE A FUNCTION. There is no function for an ADBV on my Chevy Colorado.

I you (Mike) have anything "meaningful" to add to this thread - please do.

What is your understanding of what an ADBV does?

I know what an ADBV does. If you need more info on ADBVs, just type the words in your Google search box - then click GO.

Since you have nothing to offer in this thread (2nd request I made), I will scroll-by any of your future posts inside this thread.

Triple Se7en...

I look at it this way: The Chevy Small block has a vertical filter like the 3.5L I5. From 1968 to 200x?, they spec'd a PF25 or PF35 filter with no ADBV. Some time ago, the PF35 was replaced with a PF1218, and the PF25 was replaced with a PF454.

There are a gazillion SBCs on the road, and I have never heard of ONE problem using the new ADBV filters in this application that did NOT specify an ADBV as part of the original-design filter.

I have no reason to believe that the Colorado 3.5L will be any different. I will use the new ADBV filter with confidence.

 

[novadude]

EDIT: forgot to say that both the PF1218 and PF454 HAVE the ADBV.

 

[Triple_Se7en]

I'm sure the new change to an ADBV was done to expand it's use to other vehicle engines that may need it. Filters like this one are being found on more & more vehicles. So the need to make it generic by adding the ADBV does make good business sense.

If you desire to purchase a product with a needless part that can go faulty -- then buy it. Nobody's stopping you. I will not purchase an ADBV filter - as long without an ADBV is available.

Millions of ADBVs have failed. If you haven't uncovered any, then that's nice to hear. Keep up the good luck.

What's the worst thing that can happen if the ADBV fails? It stops acting like an ADBV? Can't really hurt if it is on an engine that does not require an ADBV, right?

Seriously... not trying to be antagonistic, so I hope you do not take my comments that way. Just playing Devil's advocate. "Failed" ADBVs ususally "fail" by leaking (unless I am mistaken). Unless the manufaturer makes the ADBV out of some material that turns rock hard after 2000 mi and no longer lets oil enter the filter, I cannot think of anyway a failed ADBV would matter on a Colorado engine.

When my supply of ADBV-less PF61s dries up, I may consider switching to a filter with a silicone ADBV for peace of mine, but I won't be losing any sleep if I continue to buy PF61s. All other AC Delco DELPHI (there are 3 manufactures for Delco) filters that I have used on other cars with ADBVs have always stayed pliable at the end of an OCI.

Incidentally, I think that *maybe* PF58 and PF61 filters may be the same with the ADBV being the exception. You can be sure that is why AC DELCO would start to use ADBV on PF61s - same filter fits two applications.

Again... lighten up! Just presenting an alternate viewpoint.

 

[novadude]

BTW... shop around for AC Delcos. Sometimes Autozone carries Champion-made PF61s, Advance a mixture of Golen Mexico PF61s (junk, IMO) and Delphi PF61s. All of the ones I have been using have been Delphi, and none have had the ADBV. Delphi is what came on my truck new, and what the dealer had installed. Maybe check your dealer for PF61s without ADBVs if it is that important to you?

I would like to know how you think these millions of ADBVs are failing. When an ADBV stops working, the filter starts acting like a filter without an ADBV. Which is what you apparently insist on anyway.

So what is the problem?

 

[Triple_Se7en]

I don't have a problem - either do my non-ADBV oil filters.

In the begining of this thread, I mentioned what filters have the ADBV -- which ones do not have. What I presented was an update on the PF-61. I also mentioned my preference of filter product for this application.

If you like using an ADBV filter in this same application as mine, that's your business. I choose differently than you.

Now if you have anything to add to my thread here - that fits my application, please present it.

 

[flatlandtacoma]

Wow.

Only post on this thread if you agree with Triple Se7en's completely senseless, paranoid, illogical reasoning...

Otherwise keep your mouth shut.

Good luck with that.

I think you have that backwardsflatlander!!!

A senseless one like yourself purchase products with needless parts attached - when another product standing right next to it on store shelves exists without the needless part.

But I guess it takes a full brain to figure all that out. So let me apologize for my first-impression assumption that you are fully equipped upstairs.

I now apologize to moderators here for that remark.
I will scroll-by this poster future posts here inside this thread.

 

[flatlandtacoma]

I think this thread is pretty much done anyway. You already said it all - You are right and the rest of the world (including GM, AC Delco, and most of the aftermarket) are wrong about what is good, bad, and indifferent for your GM engine.

I now bow to your clearly superior intellect and reasoning skills. Have fun fighting those windmills Don!
