thats the first thing i would check… what size oil line are you running? -3an,-4an? its not as big of a deal on that turbo, but on a turbo like my dual ball bearing i know for sure it is a good idea to run an oil restricting fitting inline, especially with a larger -4an line. if you dont you have a chance of the high oil pressures blowing the seals in your turbo, so you could be feeding oil into the charge piping, directly into the exhaust or both. so i’d check that.
