I'm at 102k miles in a 2015 car, JB4 from 79k - 99k, EQT stage 2 since 99k, still on original IS20. I recently noticed a bit of oil in the TIP and showed this picture to my mechanic who said it likely meant the seals in the turbo were starting to go, but that I shouldn't worry about it and that if/when it does go it won't blow the engine. I'm hoping he's correct about that. I've no desire to move to a bigger turbo, unless there's something out there that can deliver the same low-end torque and quick spool, so I guess I'll be replacing with it with another one the same when it goes but I haven't really started thinking about it yet...
