yes. what size line is being used? the problem is that you are having a steady flow of oil come to an abrupt turn. think of it like driving, you are hauling *** down a stright, but have to slow way down to make the turn. same deal here, but the oil doesn't know to turn, so it all just stops at the turn and causes a build up of oil. if at all possible, try to use a straight or a 45* fitting to help the flow stay consistant
or, depending on the size line you are currently using, step up to the next larger size. i personally use -8 or -10 drain lines
