turbo oil drain

My oil recently started doing this. The oil drain line was not dumping it fast enough. I pulled the drain line and blew into it with an air tip and then put it back on. It stopped. The oil coming out of the bearings is kind of weird and frothy looking and doesn't flow well, so if the drain line is not 45 or more downward degrees, it gets backed up. Mine was the result of the angle changing to a horizontal before it hit the pan. Even one inch seemed to block it up. Mine's a 10an so it's fairly large too.
