Bleed air is basically exhaust gas, right? I've had a 65 year career as a master auto mechanic, and 30+ years as an instructor- - - -little or no jet engine skills. Automotive engines have horrendous corrosion and carbon billdup problems with exhaust gas recirculation systems. Could you be dealing with some kind of similar problems with the bleed air system?
No. Bleed air is usually taken off of the N1 compressor, around 500°f and 40psi...
