Ram 3500 6.4l hemi engine failure after using Fram oil filter

[lakestone]

1. if filter is horizontal or base down vertical you cant.

You don't have to fill it up completely, to the point where no oil is absorbed. Put some gloves on, and your thumb in it. Turn it around. That's how Subaru guys prime their old filters.

2. Cat says no, Its an easy way to get unfiltered debris into your engine.

From where? Unless you are really negligent, no likely. And I didn't think this needed explanation, but okay: make sure there are no machining debris from threading or deburring hanging around the top of the filter and at the center tube entrance. I think it's good that in 2025 we're still debating if we should prime oil filters.

After the filter, at the front of the engine above the water pump.

The the right way to measure it, before it hits resistance. The resistance to flow indicates oil pressure.

 

[SubieRubyRoo]

Do these not have a low oil pressure warning?

It’s also got a gauge… OP claims he saw “greatly reduced” oil pressure and the OEM filter went from “80kPa to 200kPa”

 

[SubieRubyRoo]

They do, but at least it's the manufacturer's filter. The liability is on the manufacturer, regardless who they contract it out to.

Sure, if the filter was proven to have a manufacturing defect.

 

[SubieRubyRoo]

That sounds like it ate the cam.

Which most likely isn’t a filter-related issue. While much more rare, there are still instances of the 6.4s lunching lifters & cam lobes aren’t there?

Yeah, they use the same lifters as the 5.7 (as does the 6.2L SC, just without MDS).

no thanks, enough oily mess from their top mounted filter without doing the prefill spill that does arguably nothing.

While Priming could be used a more exact term would be pre-filling the oil filter.

you can prime the oil filter with clear flood mode a totally different process.

Caterpillar suggests prefilling does nothing good, and introduces small possibility of contamination.

Caterpillar suggests prefilling does nothing good, and introduces small possibility of contamination.

But I think lakestone’s suggestion to see if it even gets absorbed isn’t a bad idea. If it’s really slow then maybe looking at the louvers is a good idea.

I always look at them with a flashlight. The 2 xg10060's I returned had good louvers on the bottom 50% of the center tube while the top ones were barely open.

I just use my cell phone light at the store to look down the center tube. I’ve also found uncut threads or thread shavings from time to time.

Now that you mention it I returned another fram (I think it was xg10060 for my 19 cherokee) due to having faulty threads.
Actually cut my finger when I was checking for debris.. but that would have been around 2021.

By comparison the 12pack of wix 10060 equiv I ordered afterwards for use in the 2020 ram and the jeep... were all boringly ok filters.

Oh yeah always pull the filter out of the box and inspect. There's also shipping damage. Don't forget people who might've compared filters and put them back in the wrong box.

OK ... I get your point.

 

[Shel_B]

MANN+HUMMEL makes the filters for Mopar. When's the last time you've seen one of those with louver issues? Purolator had other issues like bad drainback valves, but not louvers.

To reply to your question: Never. It's been decades since I've looked inside a filter. Last time I did was 1993 when I cut open the filter for my F-350. Other than that, I've had no interest in seeing what's inside the can and have paid almost no attention to various "cut open" filter threads here. I don't use such filters.

 

[johnmyster]

There are several things wrong with that.
1. if filter is horizontal or base down vertical you cant.
2. Cat says no, Its an easy way to get unfiltered debris into your engine.

If you can't manage to pour oil into a filter without getting garbage in there, perhaps you shant be working on cars. I mean, open box at work bench, pour oil into filter, slide under car, spin on.

I'm very sorry that you're having to go through this...I do hope that the filter was the culprit and you're not SOL. I share an identical powertrain in my 2500.

We need to define a few parameters. I’ll let the Hemi experts chime in. On a 6.4 Hemi, where is the oil pressure sensor mounted. ( the one that indicates the pressure on the dash board. )

Live data on my 5.7 shows 2 sensors. Once after the pump and one up by or in the VVT solenoid. Mine read a ~10psi difference, with the EVIC showing the lower of the 2.

They do call for 4psi at idle and a minimum of 25 at 3,000rpm for the 6.4 however.

Tech - "Boss, we got an engine failure on bay one"
Boss - "See anything obvious we can blame"
Tech - "Well, he's not using an OEM filter"
Boss - "BINGO, we have a 'culprit' right there"

I'm sure that's the reason why Cat. recommends against pre-filling.

 

[Greenbeforeblue]

Hook, line, sinker AND the bobber!

 

[wemay]

And seriously. How's pre-filling an oil filter any different than pouring oil into the crankcase? It's a much larger hole on the top of the engine. If your risking introducing contamination with one, heaven knows what's being introduced with the other.
