Thanks that helps.
According to that all scavenge/return is back through the oil coolers.
2 top lines are vents.
On this particular one, I don't know what you meant by all done internally, because anything picked up by scavenge systems is brought back through the oil cooler or its bypass, and then to tank. I know of a case where the reduction case pump has scavenge and pressure, not sure about the feed in though. Good info thanks again.
