I did not realize that you must remove the turbo oil line to remove the air cleaner bracket. I had the *&^%$ thing completely unbolted, including the PITA bolt on the bottom, but could not remove it because of the oil line being in the way. Does the turbo oil line fitting use O rings or a gasket for sealing? On both ends? I did not have the replacement O rings/gasket, so I did not change the bracket. My old one is not broken, except that the rubber isolator mount holes have become ovalized from vibration, so I had to use lock nuts on the bottom to mount the shock isolator firmly.
