Going back to my comment on oil level compared to the IMS bearing position and wanting to prove my (educated) theory correct, today I got a spare crankcase half I had lying around, like you do and got the tape measure out, I measured the engine oil dipstick tube from my 996 and deducted this length from the the length of the dipstick. I dropped what would be left of the dipstick into the same line the dipstick would run, give or take a few mm. I used a straight edge to show the line at the top of the IMS opening the results are below.
I took some pictures and you will see the upper oil level mark on the dipstick is about level with the top of the IMSB cover opening meaning the bearing which is much smaller than this hole is deep into engine oil if you keep the engine topped up to the brim as I always do.
Straight edge in white going from top of IMS cover opening and passing through the top level of the dipstick.
Obviously engine oil, once the engine is running is spread around the engine but there is always a good quantity in the sump still and easily enough to lubricate the bearing as it really does only require a small amount to lube it.
Using these pictures and my two previous together and hopefully that answers a few questions once and for all.
