I have read that, when changing oil, it is easiest to add the oil through the oil filter housing. However, when I try to pour oil into the filter housing, it does not flow into the engine quickly. The housing fills up immediately and then drains very very slowly into the engine.
I should also note that the bottom section of my oil filter holder is broken and missing (see photo). This happened before I acquired the car. I'd hate to think that the plastic pieces from the oil filter holder are inside the engine and clogging up the oil passages.
Any thoughts as to why the oil is not draining quickly into the engine?
I think you probably answered your own question. Possibly because the lower section of the oil filter assembly is in there obstructing the flow. You can look down in there with a good flashlight and see. Then remove with very long needle nose? Never heard of this one before. I hope it's as easy as I made it sound; good luck!

I doubt you can get pliers down in there and still squeeze them with your hand. I would try a flexible retrieval tool. Similar to a plumbers snake, but with three prongs at the end which can be opened and closed from the other end of the flexible tube/spring. Should be available at auto parts store.
Even then there is no way to know how much still might be stuck in there without a video camera.

You just have to remember he's like the Soup ****!
That's a good question. I have driven the car 10,000 miles since I owned it with no issues. I wonder now, though, how much oil is actually circulating through the filter. I have ordered a new oil filter assembly and will search for the obstruction with an endoscope.

If we compare the two pictures we can see that the broken part could not possibly go past the point where O-ring # 3 seals against. I imagine the broken part is as far down as the larger diameter above O-ring #3 will fit.
You just have to pull the broken part out of the lower diameter holes. This may be easier said than done.
When you pour oil in it has to flow through the smaller holes in the filter housing body which may be constricted by the broken section restricting the outflow of oil. Oil flows from the outside of the filter through the filter media and out the bottom below O-ring #3.
I would change the oil after a couple of thousand miles as the interior of the engine may have accumulated a thin layer of sludge due to poor filtering, maybe not if the oil appears quite clean after a thousand miles or so.

I would listen to this advice and follow it closely.
I would also thank my lucky stars the engine appears to not be impaired what what has been going on here.
Got it! Once I realized (with the help of people on this forum) what I was looking for, and what I was looking at, I was able to reach the broken piece with a pair of pliers and pull it out. Now, I just need to wait until the new oil filter assembly arrives. Thanks to all for your help.

GREAT Job! One bit of advice before you install the replacement, make sure that top "O" ring is in the SECOND indent. If you place it in the top most position, it'll leak and cause a huge mess in the bay.
