Requested oiling mod info

The plugging off of #1 main passage makes #2 main a direct feed as it is now the end of the passage.
When you drill and install the fitting at #4 you are drilling at an angle that puts the fitting into the oil stream. Not a 90 degree hole into the oil galley but at an angle into the oil flow.
I know it works and you will never change my mind that it doesn't.
