I have the Christian Inverted Oil system and am using the vacuum pad as the inverted oil pick-up point. I have no vacuum pump, just the block-off plate with the fitting for oil pilck-up.
When I removed the accessory case and took out the vacuum pump gear, I noticed an oil feed hole that looks to be a pressure port to oil the vacuum pump gear shaft. With the gear removed, that oil port is now open, with no restrictions. This seems like to woild cause an internal oil leak that would create low oil pressure and a loss of oil volume to other parts of the engine? The gear has to come out to feed oil to the inverted system, but what happens to the oil feed?
Also, same question on the prop governer gear shaft. I removed this gear because I am changing to a fixed pitch prop and did not need the drive gear. I see the same scenario with the oil feed in this bore.
The first photo os of the vacuum pump drive gear bore, and the second is of the prop governer drive gear bore.
Am I worried over nothing? What has been your experience here?
Thanks, Craig.
