i decided to rebuild the evo 8 mr, td05hr 16g6 10.5t..just as a precaution...i have had the turbo smoke for random reasons none of which were seal related...believe it or not i have found that tune, blowby, how your egr/pcv is routed... etc can have a drastic effect on if your setup has smoking problems..so smoke doesn not necessarily mean a blown turbo
