No it does not. My filter drains completely, which give a bit of rattle on startup, but it doesn't seem to hurt anything. There is a spin-on filter adapter I've seen posted here, but I can't imagine the cost is worth it. I would also have concerns about the torque from tightening and loosening the spin-on filter causing cracking on the not so durable filter/cooler base.

Something got screwed up. I fixed it.
That's normal. You could use clear flood mode if the car sits for more than a week if the noise really bothers you.

If there is, then it doesn't work very well. When I change oil in either of my Pentastars, if I simply wait for about 15 minutes after I shut them off to change the filter, the entire housing will be empty.
This is true, however my Durango's housing is cracked for the second time. The miles on this cracked housing is 106k. I have been certified as a non-knucklehead, as I have never tightened the housing to more than contact with the base. The o-ring drag was the only torque on the base, ever. I know this to be true, because I'm the only person that has ever tightened the filter on this housing. My opinion is the housing design is flawed.
Benefit of doubt - won’t hurt to pull the filter before drain bolt …Good Morning Everyone,
I was researching the topic of anti drain back capability for the V6 Pentastar engine and learned that in fact it has one. Below I've pasted a thread from March 26, 2023 titled "A V6 Pentastar Upgrade To Avoid" referring to the Baxter device. It is from the Dodge Challenge Forum. I included a second picture that includes how oil flows into the unit and a link to the forum. John does a nice job including instruction to pull the filter first so you drain the filter area oil and then to remove the oil pan drain plug for a complete drain.
For me this design makes perfect sense and is elegant in its simplicity. John also comments at the end how the Baxter unit creates an "inverted pendulum" which was my concern also.
Have a read and, as always, I welcome your thoughts and insights.

Watch the video first. Then I'll tell you about the Big Pentastar LIE.
There is a anti drain back valve. The engineers that designed and built the engine aren't stupid. here is how it works, look at the following picture from engineering illustrations.

For any of you that change your own oil and pull the filter up quick, you can see the canister is full of oil, and then it drains into the pan. This is also why you should change the filter first. Then you won't get a half quart of dirty oil into your new clean oil.
Remember too that excessive torque on the housing is what causes oil change knuckle heads to fracture the housing and not take the blame. If you install this adapter, you also have the weight of a full metal filter acting as an inverted pendulum on the housing.
What do you think people... Can you believe this tripe?

I hope they replaced the housing for you at no charge. Your experience with the certified knuckle head continues to reinforce the benefits of doing this work ourselves.It's a 2014 and I was told by the dealer that I got the revised filter housing, which is supposed to be a better design.
I see nothing in the cap to indicate any sort of by-pass mechanism. It's just a cap.
I agree with you 4WD.
Great outcome for you in getting the stronger revised filter housing.
I found two videos that do a good job of showing the old and new designs for the by pass valve.Great outcome for you in getting the stronger revised filter housing.
I'll see if I can find the video I watched that detailed the changes to the cap. Prior to 2014, the by-pass was in a long tower in the cartidge housing and the spring could eject with removal of the cartridge.
That port makes sense - you pull a well saturated filter - and without that port the dry filter going in could plunge oil upwards …
Oldhp I appreciate the tip. I always thought it was the plastic on plastic threads creating the resistance when reinstalling the cap. I will be trying your tip on my next oil change.
