it still seems like it should drain ok as long as the turbo is higher than the oil level and it has a consistant downward slope so it cant pool anywhere along the way. just like if you stuck a funnel in a bucket and poored oil into it, it doesnt matter if you have the bottom of the funnel in or out of the fluid in the bucket, it will still flow into it as long as the top of the funnel is exposed and above the oil level in the bucket...
