I'm Sure emsril won't address this issue with there kits so I'm gonna.
Is this happening on one of our kits? We have never had a case of this issue in 4.5 years making the kit. But we are definitely interested in finding a solution asap.
First off, what lead you to the conclusion that the issue is the return line getting overwhelmed with return oil flow and not a different issue like the oil seal on the turbo letting go or something else of the sort? I am not questioning your judgment, just want to get to the bottom of the problem
Second, is everything hooked up exactly like on our manual and using the included components? The reason I ask is that if a line was replaced or the turbo is different, or the inlet/outlet flanges are different (not restrictor perhaps) then it could cause an imbalance in the system causing too much oil to go into the turbo overwhelming the return line.
I will add that our feed line is -4an and our return line is -10an which should more than be able to take the flow...hmmm...do you think you may have a blow by issue in your engine? One way to test this is to open your oil cap with the ending running, there should be little to no pressure change, even when revving it lightly. If when revving it lightly, pressure build up on the oil fill neck then your issue might be with your engine.
Please answer these questions and we will do the best we can to find a solution for you. You can also call our main line at 612-605-9845.
