This has happened to me and 2 of my other customers all with low mile turbos 500-3000 miles. 6157E turbo.... The fix is to replace the little piston ring type seal on the exhaust wheel and the center cartidge(thanks Bison). I redid mine(T type) last year and it is now good been about 1000 miles maybe. I have another customer that got a budget PTE TE60 from gbody and he's been chasing a leak at turbo drain. He brought me the car and oil is running out the hot side at turbine leaving a coked trail....not the drain. No smoke yet. Drips on oil filter. maybe 800 miles.
I have the same turbo on my personal Gn and guess what no leaks but at extended idle it starts to smoke and with have the smell of oil before it smokes...prob turbo as well. Maybe 3k miles.
All these cars have good feed lines...stock..braided...not restricted.
Good idle oil psi 15psi and up to about 30 35 on my GN.
Stock drains,braided drains.
Turbos boost fine otherwise.
No excess crankcase pressure all basics have been covered as I am not a noob to TR's.
Anyone else seen this.
Eventually I will go to a BB on the GN so not too concerned about it.
