Off a colleague's 2021 RAM 1500 Classic 3.6L that uses synthetic 5w-20. Anyone see this failure before? A quick search revealed NO.

Wonder who makes this filter. Thank you for photos. Do we know what filter and oil went back on and in? Thank You comrade 🇨🇦🇨🇦
I'm pretty sure the same filter went back in, it's what we had in stock. I'll make sure to look out for it when it comes back for the next service in the fall. NAPA FS 5w-20 oil went in along with it.
 
^^^ Yep, wondering if the built-in filter bypass valve (in the filter housing?) is working correctly.

When we see a blowout of this magnitude we tend to think bypass failure. However, trying to rationalize something like this ultimately looks like what is below.

We can state for sure that we know there was oil flowing through that tear by which way the torn media has been placed. Potentially tearing early in the oil change interval. We can see the blowout right next to the notorious seemed pleats. The "Usual" spot that tears potentially because of, incorrect, wide pleat spacing that doesn't hold up under pressure. I think the media tears here b/c of poor quality & a rise in oil pressure.

With a rise in oil pressure I believe it tears BEFORE it reaches bypass mode. That's how much i'm placing on poor quality control. The oil filter is only as strong as its weakest link. This filter never made it into the vehicles bypass mode b/c it blew out before it ever made it there. The oil is now being bypassed, incorrectly, through the tear.

If we compare this filter to say warranty claims in the auto industry. Most warranty claims come from manufacturing defects. I would say in this situation it's probably a combination of poor quality oil filter & higher pressures but mostly poor quality control on the filter. It's most likely not a bypass failure.

What caused the oil pressure to rise? It appears they're in Canada & it could have been some really cold oil. Cold oil with a partially clogged filter. It's a newer truck so more wear metals loaded on the filter along w/the other issues etc. Regardless, that media area was not strong enough to hold so it tore. :(

Remember Purolator tear fiasco? They came out with the Boss line to straighten their reputation & provide a superior product. I'm not talking about efficiency but the tear resistance. Have we ever seen a torn Boss? I use this as an example of a quality filter that most likely won't tear (non-metal wire backed).

Another thing is how common do we see REPEAT failures on the same vehicle? We'll see a post about a tear but not really any repeat failures on the same vehicle. I think this points more towards poor quality filters rather than bad bypass valves. Not saying it doesn't happen but most of these issues is a crappy filter imo.

Using an extended mileage filter can go along way in preventing this from happening by staying away from the cheaper poorer quality filters.

What looks strange in these photos is there seems to be a loose folded over piece of media on the dirty side of the filter. Don't know if the OP messed around with the torn media and moved it around during inspection, but seems like a strange way the torn media ended up.

Hard to say it tore before bypass delta-p, or exactly when it tore. Hard to say what the max delta-p ever was ... it could have been from high delta-p spikes from cold starts in winter and the bypass valved not reacting well or fast enough. Winter time is hard on oil filters in this respect.

Yes, the most likely scenario.

More oil pressure seen on the dash means either more engine RPM (more flow) or more viscous oil, or a combination of both. The force on the media is not the actual oil pressure seen in the system, but the delta-p across the media due to the flow and viscosity. A rise in oil pressure of 20 PSI may only equate to a 1 or 2 PSI delta-p rise across the oil filter.

But the in the end, the oil filter should be designed well enough to take the delta-p across the filter all day long when the bypass valve is open. If the bypass is designed to open and maintain 15 PSI delta-p across the filter, then the filter should be able to take that all day long. If the bypass valve is malfunctioning, and/or isn't designed well then it's possible the filter gets much more delta-p across it. It might even just be short high delta-p spikes that end up taking it's toll and eventually causes the media to fail.

Yes, if it does happen again on the same vehicle, then it's most likely some other reason beside the filter unless they happen to get two bad filters in a row - remote possibility.

It's on the same general side with the rest of the damage. If it tore out that big hole it probably tore that folded over section while it was at it. :LOL:

But wouldn't you agree that if it reached bypass it most likely woudn't have torn? That's a red flag that it tore before b/c it didn't quite reach it's pressure relief (Bypass PSI). If it reached the bypass pressure then it wouldn't have torn. It just would've went into bypass.

Yes, the most likely scenario.

Which represents just how lousy this common failure area really is to delta-p. It's not taking much to blow this lousy manufactured area out.

It really should have been strong enough for sure. If it went into 15 PSI Delta-p across the filter & opened the bypass valve then there shouldn't be any real reason it would have blown out. That pressure is now somewhat flow channeled through the bypass now & putting less direct flow stress on the filter.

2 bad filters in a row... Darn the luck. haha :cautious:

And this is one of the reasons I prefer a wire backed synthetic media, the risk of this happening is essentially zero.

Absolutely, There is some sketchy QC out there on the lower tiered filters & I consequently buy at least the extended 10k+ filters. When I really think about it... It really makes even the Boss 99%@35 microns a good deal still. It may not be very efficient but at least it won't blow out. 😅 We can all agree that we want our oil to be filtered and not bypassed.

But all the torn and loose media should be pushed towards and through the center tube. Don't know how a big piece would be pushed outward and folded back onto the dirty side. That's what the photo seems to show, but maybe I'm looking at it wrong.

The circled chunk is what looks foldefld back over onto the dirty side. Can see the torn end in upper right of the circle. Or is that the remains of a whole pleat - hard to tell in the photo. Maybe there was a major manufacture flaw when new, and it was installed without close inspection and it wasn't seen. If so, doomed to fail from the get-go.

Don't know at what delta-p it tore at. It could have torn before bypass, at bypass or even beyond bypass if something caused the delta-p to go above the bypass valve setting for some reason as I previously descriped. All we know is that it tore from delta-p. Assuming the bypass valve worked correctly, all we can conclude is the filter was faulty. If another filter brand/model also blows out, I'd suspect the bypass valve operation.
 
Maybe @GSCJR could separate and unfold, etc the media in the blown-out area to do a bit of "failure forensics" to determine how the delta-p caused the media to end up that way.
