I'm fitting a turbo to my 617 engine, and was planning to copy the STT turbo kit where the oil return line is connected to the oil drain plug. A hose from the servo on my w123 fits perfectly to the drain plug hole, using the "banjo coupling" and the bolt from the servo. The only difference from the original would be that the flow will be more restricted, and then the question is, is it good enough?

Of course the first advice to myself is to replace the whole oil pan, but I only have the turbo, and I wanted to try this shortcut. Any opinions on this matter will be appreciated.
