Oil Filter Draining Test

If you could stop trying to entrap people with words it would be nice. It was a guess, since you put up a pic, I don’t know exactly how much your filter holds on the dirty side. Lighten up.
Reading comprehension helps ... it was explained exactly what I did in the first post. You're entrapping yourself. There was no oil on the dirty side from the center tube involved in any way. Look at the photo in post 12 and you'll see how much oil was tapped on the dirt side of the filter before I put the hole in the dome to make it drain into the glass bottle.

That’s right, the Toyotas don’t drain down more than other filters with excellent adbvs, as you experienced.
This isn't about filters draining down by themselves while on the engine, so don't know how you got on to the subject. It's about showing what to do so the filter DOES drain out when you want to change the oil filter and don't want it to puke all over the place. If it drains down by itself, then there's no need to make it drain by punching a hole in the dome.

You said something about a stand pipe on the 4.0, maybe on the FJ. I didn’t say it, it was either another member or you. I think it was you who said it, because I never heard of that stand pipe before.
Go find the guy who actually talked about it. I've never claimed there is a standpipe is in any Toyota V6 engine. Besides, it would be in the oil filter and not on the engine if it took a spin-on.

My Silverado with the 4.8 holds a lot of oil above the filter also. I have used the punch trick and it works. On my Cummins not having an ADBV, the filter will only be about half full and has a pretty good amount of oil that comes out of the oil pan after cracking the filter loose.
 
If one plans to use the filter again (a separate controversy, I know), there are less destructive ways of allowing air in, in order to drain the oil. I've done it by gently poking the ADBV, or by spanking the dome end.
 
^^^ Yeah, don't put a hole in the dome if you plan on using the filter for a 2nd OCI. I'd like to see what kind of oil stream would shoot out of the hole with 60 PSI inside the can. :oops::D
