NOTE** The picture is NOT my car or engine only used for example**

Would this be alright for a oil return being the line goes down and below the actual tap in the oil pan or does it need to be a constant angle going into the pan? On my car I cant get a good angle because of subframe so I either have a tight bend and restrics the oil retun hose size but has decent angle or I run about 1 foot of line simular to this that would go around my intercooler pipe.

 

no not a good oil return line.. As you see the oil has to flow up a hill into the oil pan. thats not flowing very well now is it. now if you would put a 90 Degree AN fitting off the turbo then over to the pan you would be fine. even a 45degree angle would work in that picture.
