Go with a Wix 51348 it's a full flow filter.Turn it over ,twist it a bit and check.
I believe this is exactly what happened - the oil did not leave the filter via the inlet holes but rather the center outlet hole because it was syphoned out over the 5 hour drain period.quote:

They DO have an ADBV, just not a bypass valve (which is intergral with the oil filter mount).quote:

Does seem to defy logic, doesn't it? It happened to one of our moderators over at PassatWorld. He left his drain plug out for 3 hours before removing the oil filter and discovered that the filter was only half full. Normally removing the filter results in a big mess because of the angle of the filter.quote:

The oil simply drained back through the ADBV. No need to defy the laws of Physics.quote:

If the oil filter is higher than the lowest point in the lubricating circuit, then yes, it may be siphoned out, if, there is already an air pocket somewhere between the sump pickup and the oil filter, or your oil has one heck of a vapor pressure. However, there are numerous open points in the oil circuit between the lowest point and the oil filter where air can get sucked in, again making it highly unlikely it'll drain the filter dry.quote:

Doesn't have to be lower than the level of the pan, just lower than the level of the oil in the filter. I guess your logic might apply if you are thinking of the oil in the pick-up tube as a contiguous flow all the way through the filter....however when the engine shuts down this isn't the case, even with the best ADBV.
It happened twice on my 260K mile beater. Remote higher than pan.
Never happened on the 850. (filter as low as the oil pan)
You're obviously mistaking siphoning with fluid which is simply flowing downhill.quote:

All I will say is that it can and does happen - the rareness of the occurence is some testimony to the oddness of aligned events. The ADBV is not air tight, but given a certain (low) level in the pan or many hours after draining oil, etc then an air pocket can exist.
Exactly.quote:

A simple and effective remedy is simply to change the oil filter.
No, you are obviously failing to understand what I am trying to explain. In the cases I have observed the filters were opening side up. The fluid did not simply flow downhillquote:

Well...not knowing how you plumbed your remote filter, you may be right. Sucked the filter dry, did it?quote:

How empty was it?quote:

Interesting that it would suck that much oil through the filter paper, but no air.quote:
