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?
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.
