I pulled my intercooler to change the starter and there was some thick sticky oil residue in the intercooler. No metal flakes or anything like that but it still concerned me so I pulled the downpipe to check the shaft play on the turbo and there was no sign that the blades were contacting the housing and shaft did not seem too loose although I'm not sure what is too loose. No smoke when running, no measurable loss of oil. It's an 09 auto that I bought from the original owner two years ago with just 55k miles then and 86k miles now. All stock and good maintenance records, oil changes 3500 miles.
Should I be concerned that my turbo may be going? Is some oil past the turbo oil seals normal?
