A Different Oil Filter Question

[CarbonSteel]

Add Fram to the list of twisters.

Thanks!

I think they all twist to some degree...just par for the course with the design.

I hear this lack of an anti drain back valve concern a lot.
This is not a real on the 3.6l.
Let me prove it to you.
The next time you change your oil, drain the pan first. Leave the drain plug out. Wait what ever time you wish, and when you want, start to unscrew the oil filter cap for removal. When the vacuum is broken in the filter housing, you will hear the oil from the oil lines going to filter come rushing out and see the oil come rushing out of the “empty“ oil pan drain plug hole.
The OEM filter assemble creates a vacuum effect in the oil
pick up tube that prevents the oil from draining back into the pan.
Additionally, if the is oil in the pan, the vacuum suspended oil in the pick tube will remain there almost indefinitely.This is the exact same grade school science class project as dipping a straw in a tall glass of water. Put your finger over the top of the straw and lift the straw out of the glass. The water will stay suspended in the straw for a very long time. Now if left the bottom tip of the straw in the glass of water, the water would remain in the straw indefinitely.
So I cannot see see any problem or fault with the the OEM existing design.
Try it and see If you doubt me.

I believe you 100% as this is how I change my oil. However the system is not sealed 100%. It slowly bleeds down. In a week or so the filter housing is empty.

I’m not going to test it but I do know after 2-3 days, like over the weekend, I’m more apt to get valvetrain noise. Seems to be the norm.

Been using Fram EG for 7 years now, not one time has one ever twisted…have always done my own work….actually this is the first I’ve heard of it….

I’m running a Fram Endurance filter currently and have a Carquest EP on deck. I’ll post pics after each use.

Only time I’ve seen this on canister filters on vehicles is due to restriction. Go from a thin oil to a higher viscosity…or that AND the filter has something more in the pleats than normal. Some filters start out more restrictive so maybe it doesn’t take as much to get it to happen.

I believe you might be referring to lifter bleed down?
