Will horizontal filter be empty after sitting?

I am getting restless on the little thimble filter on my car for the ARX treatment. It's almost 10 inches above the pan, and is horizontal. I am wondering how much of a mess it will be to take it off and put on another one. I would pull it in the morning.
 
You can bet it will drain some,just have your catch pan ready.

shouldn't loose any out of the pan tho just the filter..
 
They are designed to retain oil, even if upside down. Yes, you will have some spill as you pull the filter off. Try to turn it up a quickly as possible.
 
The last PL-14459 I changed on my old Honda had no oil to drip when I took it off after resting overnight. This is a horizontal installation. Made me wonder about the silicone ADBV in the Pure One. I replaced it with a similar one, will let this one rest over night too and see if it retains enough oil to drip on removal. (Next OC due in a couple of weeks or so.)
 
I just changed the oil in my Sister's 1997 Honda Civic with the 1.6L I-4 engine. The car had been setting for several days when I changed the oil. This is a horizontal filter. The filter did not drip any oil when I loosened it and it was practiaclly empty when I tried to shake out any oil remining in the filter. I eventually cut the filter open and it did contain some oil, but not much. The filter in question was a Wix 51334. I have had this happen before when I removed the filter from the car when it was dead cold. I don't know whether to be worried about this or not. The Wix filter has a silicone ant-drain back valve. I examined the ADBV when I cut the filter open. The ADBV appeared to be flexible and sealing the filter openings properly. It is my assumption that the oil is leaking back through the output side of the filter (possibly through the bearings?). This Honda is the only vehicle I have where this happens. I have several farm tractors with oil filters mounted horizontally to the block, like the Honda, and they always ahve significant amounts of oil in the filter whne they are removed, even if the tractor has been setting for weeks. The Honda has well over 130,000 miles, so I suppose this can't be a major problem, but I do find it worrisome. A picture of the fitler I cut open is at http://home.earthlink.net/~cewhite3nc/id10.html .

It seems that in the Honda I4 engines where the filter sits horizontally a foot or so above the sump the oil drains back over the hours, regardless of ADBV. Does that mean that a lame FRAM ADBV would be good enough for these?

My 13yr old Honda has almost 220k miles, so it survives this drain back. In my ten year old Nissan VQ (i30) the oil filter is very close to the sump level. Here even with a Puro PP the filter stays pretty full days after the engine has run. To me this suggests that with enough gravity it drains back regardless of ADBV, as blupupher explains.
 
I will try to get it off this weekend, and see what happens. Hopefully the ¾ thread filter will work, so I can put a sandwich adapter on it and run an MG.
 
Lets see... We have a liquid (oil) seperated from it's home (the oil pan)n by a porus material (the filter media), in a possible siphon causing environment. Hmmmmm, I wonder why the oil leaks out?????
 
Pete, the ADBV should still, ideally, prevent the oil from draining BACK into the pan (against the normal flow of the pump). The ADBV is between the oil in the filter and the oil intake in the pan, unless I simply can't imagine what we're writing about. And IF oil were to be siphoned the other (forward) direction the filter would not empty because more oil would be drawn up the intake.
 
No, BZD, oil can surely drain forward. It's not a closed system. It depends on how high the filter is mounted on the block. If it has to travel "up" to a gallery ..then it will not drain forward. The ADBV doesn't have to be perfect. It only has to prevent rapid drain back. It usually does hold between starts though ..at least in some filters.
 
I'm using an oversized Baldwin on an 02 Civic with the 1.7L engine ans oil allways gushes out and over the axle shaft when I take it off.Mind you the car didn't sit very long before I removed the filter,but there's alot in there when I take it off.Why does'nt Honda/Toyota ,with all their design smarts,think of a better place for an item that needs attention on a regular basis?Anywho...after sitting some oil will seep thru the element back into the pan.How much depends on filter placement and design of system.Small block Chevy's of yester year had no drain back and no anti-drainback valve because the filter was face up to the block.The older Jeep 4.0L engines had the oppsite,almost face down,but had a long "stand pipe" off the filter mount and an anti-drainback valve on the filter to keep the oil from seeping out of the filter.It depends on the design from the engineering standpoint.
 
Last summer, I pulled a SuperTech ST3593A off a '96 Civic EX that had been sitting overnight. The filter was removable by hand (insufficiently tightened), but not a drop of oil leaked out when I removed the filter. The filter seemed to be nearly empty as well. The filter probably had around 5k miles on it.
 
Girlfriend's '93 MX-6 2.0L has a nearly horizontal filter, and it is empty every time I remove it. I've used NAPA, Supertech, and Purolater filters on it and they're always empty. I guess that's a good reason to have such a small filter on there.
 
I tried to get the filter off, but the mounting is weird. I had to remove the license plate to get to the filter. The filter mount is smaller than the AA-3600 I have for it, and it doesn’t look like I will have enough base to mount the 3600 I have. I will try to get some measurements tonight, and see how it works. It looks to me like the filter gasket of the OEM filter will fit inside the 3600 filter gasket by a little. I will see what I can find out, and then maybe start another thread looking for an extremely small gasketed ¾ by 16 filter. I seem to have about 10 inches of height, if I can get narrow enough to get by the AC condenser.
 
OD shows to be about 6 cm. Now that I have the filter and it's box, I have a whole lot of numbers that I can cross rreference, including what looks like a UPC symbol.
 
It really isn't required to stop anything. It only has to stop rapid backflow. Besides ..what harm is there to "dirty" oil going back where it just came from

I wish the guy at mini-mopar had really thought that out a little more before putting so much emphasis on that. He's the guy who did the first oil filter comparison ..back some time ago. In the original study, he appeared to perseverate on it. "....and it may allow dirty oil to flow back to the sump" (yes, exactly where it came from in exactly the same state that it left there in)
