Another turbo rebuild at PRE. This time we received a Subaru turbo that suffered a catastrophic failure. This turbo broke the turbine shaft due to lack of lubrication. Compressor wheel, bearing housing, turbine rotor shaft, and all consumable parts(bearings, thrust collar, shaft seals, o-rings, clips, and hardware). Turbine housing was media blasted by hand and polished afterwards. Turbine housing is ported and blended in the turbine inlet, wastegate area, and turbine outlet. Compressor housing passed inspection and received proper cleaning. Rotating assembly was balanced on a Schenck turbo balancing machine. (Note to all Subaru owners; clean or remove the oil filter for the turbo oil feed line. This clogged filter caused complete turbo destruction in minutes!)
