AcDelco PF61 Champ Classic Cut Open!

[Herz]

This filter came off my weekend truck, a 2005 Chevy Silverado LT 5.3l V8 with exactly 53000. Time on the oil and filter was roughly 4500 miles since mid August last year. OLM read 42%. I changed it out because I don't like oil sitting in the car for more than 6 months and the truck sees 75% short trips and sits in the garage. This is a champion classic AcDelco, I replaced it with a Purolator I got with the Valvoline pep-girls rebate.

The filter held up well, can is thick (to be expected with champ,) media not distorted or damaged at all, well built filter. I have one of these classic PF52s on my Sierra ATM that I had in my garage for over a year now.

Forgot to mention the oil was either Valvoline WB or Chevron Supreme 5-30.
Enjoy!

excellent!

SO, It's confirmed then, The PF61 DOES have an ADBV.

 

[Herz]

I beleive it is also a combo bypass valve, the bottom end cap of the media was sealed shut.

 

[labman]

No second set of holes for the bypass. Typical GM application without a bypass.

Yes it had an ADBV. I trust those that have reported PF61's without them.

looks like you're about to serve lunch with those gloves lol

good pics

Are you calling this a 'classic' because it's not made anymore or because it's not an Ecore or both? Are they still being made, or is this one of the apps being stocked up on, because of the change to Ecore design?

No bypass, what's with that? Must only be for selective apps with a built in engine bypass?

Limited applications. Other than that, looks well made.

Must be difficult to have use the authentic 'Classic' by Purolator.

The 'Classic' that is still being made for mutiple applications.

Thanks for the pics.

Yeah this one was switched to an ecore design, the no bypass is odd, never noticed it before. I wonder if my classic PF52 is the same. I call whatever champ with metal end-caps the classic design because they are all being converted to e-core eventually, according to champ atlease. I highly doubt the M1 and KN filters will go ecore.

As far as the bypass goes im sure GM specced it like that. Hehe, the purolator classic is a good filter just 4.00 plus tax here. The WIX pf52 I cut open also had a sealed bottom, never put much thought to it so it did not have a bypass either. However, the ST3980 Ecore (pf52 equivilant) had a thread end bypass... I do not understand how GM thinks sometimes.

I think defektes means the older pre Ecore style of Champ filter when he says classic. Since it can be confused with the similar Purolator Classics, it may not be the best choice of words.

Not sure what Champ is up to. I don't work for them. It has been several years since they announced they were switching 11 numbers to the Ecore and more to follow. Several numbers are still around in the older designs, ST 3593A, STP 3950 and some others I don't remember. I thought the AC's changed when the others did, but I guess not. My guess is if any ST or STP equivalents haven't been changed yet, the AC won't either for now. Maybe they are waiting for the economy to pick up before investing in more equipment to build Ecores.

GM has long used the bypass in the engine. I have cut up a bunch of PF 47's and PF 52's and none of them ever had a bypass. I checked and the Wix and Fram numbers don't have a bypass either. Maybe Purolator cuts corners by selling the same filter for both bypass and non bypass applications.

Anything with steel end caps looks good to you.

Yeah, it's been a GM thing on their V8s from many years to have a built-in oil filter bypass valve near where the filter mounts on the block.

Purolator makes filters with no bypass valve also for GM applications.

My 2003 5.3 liter takes the PF46. I have not used them yet I just bought 3 I will be changing my oil in a few weeks. I am glad you had good results

 

[Herz]

You can use the pf61 if you like, its a bit longer about a inch and a half.

....And any oil filter that says Purolator on it looks bad to you.

People who live in glass houses.....

Traditional metal endcaps and center tube, with separate bypass and adbv are still the design of choice for all the high line filters, including Champ made M1 and K&N. Even the OP recognizes they are not likely to switch to an Ecore design. Being in denial won't change that fact.

Nice try on the "Puro cuts corners", looks like Busa put that tale to rest. I just wondered why no bypass, and as I said it would have limited applications.

Again, the traditional AC Delco design looks good, much like a Purolator Classic. Constructionwise, it's easy to see why many would prefer the traditional AC Delco design, over the new Ecore design, I would. Fortunately Purolator still makes em' that way for a reasonable price.

Are you sure you don't work for Champ?

Hey it was an AC filter. You are only learning now that GM commonly puts the bypass in the engine?

 

[Sayjac]

So you the authority on GM engines that have a bypass built into engine, congratulations. Having not owned a GM vehicle configured as such, it would be of little importance to me. IIRC, seems as though I may have read a post with some reference to it. What I do know is, generally speaking, no bypass is the exception rather than the rule. Thus, limited applications.

Back to the topic, the traditional AC Delco does look much like the Purolator Classic in design, so perhaps the OP is on to something calling it 'classic'. Understandable that some would regret it's replacement with an ecore.

 

[Herz]

I am fine with the e-cores, but this I reffer to as classic due to it being the original champion design that is discontinued in most popular applications.

Ah these are the girls gloves she uses for coloring her hair, I only use them to not waste my good Nitrile gloves lol.

Saw the PF 61 today at Wally, one of the few AC's they stock. It was an Ecore, this must be another one the apps that has been switched over. It's ~ 0.80 more than an ST, don't know if there's any difference in the media.

 

[labman]

The PF 61 crosses to a 3675 or 9837. Has Champ been producing one in their other brands, and if so, was it an Ecore all along? Are they expanding their Ecores except for AC's or just bring the AC's up to date?

 

[Herz]

This filter is one of the original batches of "popular" filters that were converted at the begining. ALL the acdelcos at my wal-mart are now ecore. They have been ecore for about 7 or 8 months now. I had this AcDelco in my garage with my 52s that I bought in early 2008 in bulk. I never looked at a ST for this application cause I figured with the OLM i'd just pay less than a dollar more and get the GM media.
