I have a 2005 Legacy GT, I completely rebuilt the engine including heads. I put in new banjo bolts, within 40 miles the turbo suddenly burned out. (Lack of oil) I did not drive it, I towed it in replaced the turbo, removed filters from banjo bolts, there was partial blockage in banjo filters but almost nothing was in the oil. Just to be safe I flushed the oil 3 times. I had before turbo, and still have code p0011 & p0021 car runs fine other than sometimes I hear an engine rattle coming down from acceleration over 4500 - 5000 rpm for just a moment, (not rod knock) I swapped AVCS control valves on both sides three times with no change. Timing is set right on. Any other suggestions?
