I have a question for some of the more knowledgeable folks on here. If a filter application doesn’t require an ADBV, such as on my 6.7 Cummins, would there be any harm in using a filter with an ADBV ? I have access to a Wix filter for 6.7b Cummins that contains an ADBV and I’m wondering if the drain back valve might help with the oil drain down occurring during periods of non use. TIA

An ADBV won’t hurt anything at all.
Count me as in the @Propflux01 camp. Having an adbv even where not spec'd originally, hurts nothing. I'd say depending on the length of non use, likely to help in preventing drain back.
Using an ADBV when it isn’t required or spec’d for the application.Sorry I'm late, how can I solve all your problems in life today?
Are you trying to take advantage of the 13 micron nominal rating of the 57136 vs. the usual 57620 with 20 micron nominal rating?
No. Trying to take advantage of the ADBV since every time the truck is cut off, it empties the filter. Trying to see if this can have an effect on the hydraulic lifters/cam service life. The truck only gets driven once a week at times when not towing.
I’m actually going to run the Baldwin B7181 filter.
Which way is the filter mounted with your setup? Gasket up, down, 90°. Just curious.
Gasket up. Vertical. It sucks half of the oil out of the filter every time it is shut down hot. Just wondering if an ADBV will stop that and keep the oil system primed.

It should help to stop syphoning to have the valve.
Is it a siphon effect?
Absolutely. I’m pretty sure it’s going to make a mess when the filter is changed if it does have the ADBV but once every 6-8 months shouldn’t be too bad if I use the gallon bag trick.
I’m going to try it and see how it goes.
Even when a filter is mounted vertically with the base up, the ADBV prevents oil above the filter from back flowing to the sump. It's been a long on going misconception that a vertical base up mounted filter doesn't need an ADBV.
My 2008 Silverado filter is mounted vertically but the filter does have an ADBV. There’s a pretty good amount of oil that rushes out when the filter is removed. The B7181 Baldwin filter is basically the same filter as a BT7349 except with the ADBV.
C5 Corvettes with the LS1/LS6 V8 all have the filter mounted vertical with the base up, and all the filters specified for it have an ADBV.

Then again cartridge oil filters like in the Toyota 2gr engine have no adbv. I had that engine and the oil light went out almost instantly. Oil filter base up. Or Toyotas with the base down oil filter high up on the engine. Something must have been designed into the oil circuit. Maybe the oil pump?
Engines with a cartridge filter typically have some kind of ADBV (check valve) built into the cartridge housing.
My Tacoma spin-on mounted vertical with the base down on top of the engine has an ADBV. Need to punch a hole in the dome to get that filter to drain before removal.
There's no real good reason for a spin-on not to have an ADBV.
