Hello! I'm struggling to find info I need straight from googling, so I figured I aught to come ask you guys. On an F20c (or F22c) block, can you guys help me label the features (oil vs coolant passages, mostly) specifically on the bottom of the top half of the block and and top of the bottom half of the block. I have some pictures that I'll attach, but if you guys have better pics I would greatly appreciate it if you could share them.

In the first image, for example, are the holes on the outside of the 2nd and 4th crank bearing supports for oil or coolant? Similarly, what about the two holes on the near side of the block near the outside 1st and 5th crank bearing supports? What about the small holes right next to the cylinders? oil squirters?

In the third image, what are the oblong holes on the near side?

Thanks for your time!

 

Those maybe oil return paths from head to oil pan.
