My buddy thought his car's turbos were blown for a long time. Started smoking at like 70k miles. At 99k he checked the (original) turbos, no oil found in them. These turbos made a very loud siren sound. Apon further inspection the turbos were made out to be 100% in working order even with the siren, and they found the stem seals to have crapped out. He would get smoke on deccel no matter what oil temp fully catless. When he put the cats back on their was no smoke.
