COLAPSED FILTER MEDIA

[Winston]

PF53 is the recommended filter for that Toyota from the AC Delco site. Remember, the bypass valve is built into the ADBV on an ECore. Are you sure there is no bypass valve?

Maybe this IS more proof that they are no good.

That ac-pf53 xrefs to the fram ph3614, and the wix 51348 as mentioned above, they all have a bypass built-in to the filter.
Also here is a Gary Allen comment from yesterday:

“I just so happen to have a 3614 sitting right in front of me ...and it's an ecore. The bypass valve is integrated to the ADBV. You'll note TWO sets of holes. 8 on the exterior rim of the can just inside the gasket ..and 6 surrounding the center threaded hole. The flow pushes the ADBV open to reach the outside of the media ..if that pressure gets too high ..it pushes the flapper further and exposes the holes that access the center tube”

The correct Ecore may be fine.
Doesn’t sound too fine to me

Westex39, any way you can take pics?

Sorry I don't have any way to take pictures. I need to take another look at the ADBV and bypass valve combination. I didn't realize it worked that way. That still doesn't explain the filter media being crushed. I am assuming that the media was crushed by oil pressure. there were about 3 pleats crushed into the center. I did not see any holes in it though. It's possible that this may be a manufacturing defect. This filter was installed by the Chevy dealership where I bought the toyota used.
This engine has pretty high normal oil pressure.
(36 to 71 psi at 3000 rpm. It will go to 80 psi before the oil pressure relief valve kicks in.
Not bad for a truck with 89500 miles.
Anyway, thanks for your comments. I did learn something about the E-core bypass valve operation.

Don't you know that all filter manufacturers make their filters to meet auto manufacturers specifications? You must have operated the truck outside of the recommended operating conditions. I need to know the OCI, the UOA, the weight of the oil, the average temperature in your area, the date code of each quart of oil put in the engine.

How can you blame the filter? Do you really think a filter mfg would choose a filter media that would crush if it was operated under normal conditions?!?!?

OMG somebody possessed my body and made me type that.

Winston,

The oil was Castrol GTX 10W-30. This oil had been in for only 1492 miles.Temps in our area run from 60 to about 95 this time of year. No UOA and since this oil was installed by the dealer I would not have a date code.
As stated above I not exactly sure what happened to this filter. I just know what it looked like when I cut it open. I cut open every filter I use and have never found one that looked like this. I have used AC Delco a lot but have never used the E-core before.

Thanks westex.

I am sorry, I was being sarcastic. I was immitating Filter Guy.

10W30. 60-90 deg F Only 1492 MILES!!!

westex,

Welcome to the collapsed media E-core club. I have cut open a few hundred of them at the shop. I have seen that phenomenon many times, with drains just over 3400 miles. The problem is their thermal bonding does not work. If you look at where the pleat was supposed to meet the endcap you will see where it came loose. Pull out slightly on the media at the endcap and you can see the gaping hole that the oil was bypassing the filter through. I have seen several E-cores where 5 or 6 pleats had come loose from the endcap, and others where there is not even an indention in the endcap media, which tells me it left the factory unsealed. The E-core is just cost cutting junk IMO.

Winston,
You forgot to offer the plant tour...

 

[westex39]

Lubeowner,

You are exactly right. There was a place where the end cap had come loose from the filter pleats which coinsided with the pleats that were collapsed. This is my first and last time with an E-core. Unless of course all the filters go that way.

You only get a B- for your imitataion, you forget to mention your credentials and experiance.

westex39:

Call 1-800-882-0890 and ask for a filter retrieval kit. Save all your parts and send the filter back to CHamp.

You will get a service report on the filter. I'm sure they'd like to see it.

You might also want to read the technical service bulletin DIAGNOSING ENGINE OIL FILTERS WITH COLLAPSED CENTER TUBES listed here:

Dang!
Forgot to request the FILTER RETRIEVAL KIT!
It is the duty of every American to request the FILTER RETRIEVAL KIT! or, ask for one during the plant tour, saves shipping costs...

Westex39- be sure to include incidental damages done to your engine...otherwise, don't waste your time with those clowns........

 

[lubeowner]

Had the opportunity to cut open my first PH8A E-core today, as we switched away from Champ right when we got our first shipment of E-core PH8A's so we didn't get many in the field.

Guess what? 4000k miles, 5w30, lower endcap flopping and loose on 1/3 of the filter diameter. Upper endcap had 4 loose pleats adjacent to eachother.

PLANT TOUR!!!!
NEED FILTER RETRIEVAL KIT!!!!

sound effects...bzzt...tnk.tnk...zzzt
short circuiting!!!!!!!!!!!!!
aaaggghhhh

 

[pscholte]

Boy, I wish the GC Elves made filters too so we could get past all this...does JC Whitney sell those toilet paper filter add ons? Do the cardboard tubes count as an E-Core?...should I refuse to become a member of the E-Core corps...it's all so confusing

all I want to do is protect my engine...is that too much to ask?

 

[westex39]

I just removed a AC Delco PF53 filter from my 1998 Toyota Tacoma pickup with a 4 cylinder engine (2RZ-FE). Upon cutting is open it was the E-core design. The filter media was collapsed. This filter does not have a bypass valve built into it. To my knowledge this Toyota engine does not have an internal bypass valve like the GM V-8's. The wix filter (51348) I installed appeared to have one built into it at the top.
All Toyota owners might want to be careful of this.

 

[labman]

Using a non bypass filter on a non bypass engine is one of the surest ways to get in trouble substituting filters. How did the center tube hold up? I hope none of the anti Ecore crowd seize on this a proof they are no good. The correct Ecore may be fine.

Lubeowner has pointed out he doesn't see the failure of clicker style bypass filters on GM products. If an unneeded bypass sticks closed, no problem.

I can sympathize.

You have someone who posts that he has an apparent problem with a filter. He starts a thread asking for help.

He gets a good reply, as he did not know how to look for the by-pass in the filter.

Which means he may also not know what a collapsed filter is. But no one had explained that to him.

So I gave him a link that would explain what a collapsed center tube looks like and what causes it. And explained how to handle his "apparent" problem.


Then you get the funny guys. The one's who want to take the mickey with someone who has , to him, a serious problem.

I bet these same guys, when driving past a broken down vehicle on the side of the road, give the driver the one finger salute and yell..that's what you get for driving that insert name ( Ford, GM, Chrysler, German, Japanese, etc) piece of junk.

I suppose to them, all he has to do is not use the same brand filter , switch to their filter, and all problems will just happily disappear. Problem solved.

Unfortunately, if it is a collapsed center tube there are potentially more problems to deal with. Where switching filters may not be the solution.

And of course their brand of filter never has had any warranties because their filter company doesn't need a warranty department. So switching to thier brand solves everything. As they say, ignorance is bliss, their filters never have problems. No sireee bob..

So if Westex does end up with an engine problem related to a filter problem and he follows their advice he's out money for not returning the filter and protecting himself for future eventualities. Yeah, they're really funny they are. Bet they'll chip in to help him with the repairs...

Whereas if he follows my advice and sends the filter back he, if the filter is found to have a problem, will be protected. I bet he won't think my advice is funny then...

As they say in sports..form is temporary, class is permanent. From some posts by the funny guys in this thread..they've had some form when discussing filter issues, but the lack of class shows through in the end..

So I can sympathize pscholte ...
