Secondary Turbo Oil Leak?
Attached are a few PICs of the oil leak. The car has 29k on the stock engine and turbos. I checked the primary and secondary oil return lines and the bolts are torqued correctly (the front turbo connection does not show any indication of a leak). I'm guessing that the crush washers for the oil return line on the rear turbo are the culprit, but would like to hear from those that have run into similar problems or can offer suggestions.

I had the same problem a few years ago and it looks like you're leaking around the banjo bolt/crush washers to me. Get a new set, clean the mating surfaces, reassemble, and retorque.

I think my secondary has an internal leak. Only 32k on original motor and turbos. I thought the turbos were supposed to last longer than that, especially with a stock setup..

I'm not sure if what you have is the same thing or not. I think if theres a lot of oil in your air pipes (check the crossover), then that's a sign of an internal leak. Which, as far as i know, means rebuild--correct me if I'm wrong here anybody, I'm still not sure what to do with mine.

In my case, the air pipes are clean to and from the turbo. I looked at your thread and did not have oil blowing onto the outside of the rear turbo intake pipe. To add, I also drained the coolant (in the process of installing a Koyo radiator) and did not find oil leaking into the coolant system.
