"I recently had my stb engine
"I recently had my stb engine turbo rebuilt due to black smoke. 6-71 485 Detroit / Covnington. This solved the problem...No More Smoke. New Problem...after just 25 hours of use, the turbo filter became so clogged with black zoot and oil that the filter was torn as it was sucked in. (The filter had been cleasned at the time the turbo was rebuilt) Any ideas on what may have caused this filter clog eventhough the turbo was rebuilt? No smoke anywhere Stern or engine room."
