It's spring loaded so that the oil should drain when the cap is removed. It isn't a big deal though. Nothing to worry about.

Do you E46 guys have the same two little green o-rings we have on our E39 M54's which keeps the oil inside the filter canister UNTIL you remove the cap?

Do you replace them periodically?
- What is the complete list of o-rings to order for routine oil change maintenance tasks (1)

While Bluebee's post doesn't really address your question specifically, his post has helped to spark reasons as to why your OFH stays full of oil when you take the top off. (Maybe he just wants us to think for ourselves...)

So let me ask you this--Could it be possible that your tip with the 2 o-rings has broken off from the top and stays seated? Thus preventing the oil from draining back to the pan/sump.

If not, then maybe something is obstructing the flow of oil back throught that passage? Maybe some material from an old filter found its way in there.

As you surmised, we have discussed the purpose of those o-rings (and the tip specifically), and have come to the conclusion that the stem keeps the oil INSIDE the housing (for startup purposes):
- How to properly change the oil in the I6 engine (1) & how NOT to change it (1)

Patent 5,516,425


Of course, if the stem is broken off, then it will STILL keep the oil in the filter housing, so, that's the very first thing I would check.

Here's a picture from that thread showing the stem in my M54 (ignore the captions as we've found out all the o-ring sizes by now):

Bentley calls to replace them every oil change, so I do them every other change.

Parts guy at my dealership says he does not stock them (had to order for me) and never had a mechanic ask for them when doing an oil change!

From a functional standpoint, does anyone here know WHAT happens if the o-rings are leaking?

I suppose what happens is that the oil in the canister simply leaks down into the sump.

What that means, I'm not sure, but, presumably it means that the engine will be slightly starved for oil upon startup.

Now, how much that MATTERS is what I'm trying to get at - which I have no idea of.

Anyone know more about this?

EDIT: I didn't find the answer in the patent itself.

A flat gasket sealing surface is located on the bottom surface, wherein the gasket surface is perpendicular with the male threaded portion. The housing comprises three passages: (i) a first passage adapted to permit flow of dirty oil to an oil filter mounted on the male threaded portion; (ii) a second passage adapted to permit flow of filtered oil away from an oil filter mounted on the male threaded portion; and, (iii) a third passage adapted to permit drainage of oil from the open-topped chamber. The upper housing unit is removably attached to the lower housing unit, and is adapted to cover the open-topped chamber. Methods of maintaining the filter and of adding refill oil are facilitated by this housing.
