    Hi, i have s60 14l with 2mil miles on it, original air compressor. Im suspecting there might be exhaust leaking through compressor but im not 100%. Sometimes when air discharges i can smell it. Is it possible, to leak? Thank you

    No. At 2mil, you're going to have a bit of "blowby" out the engine breather tube. This is compression gases getting into the crankcase and contaminating the engine oil. The compressor uses this same oil to lubricate, and at 2mil on the compressor, it will have a bit of wear too. The smell of compression gases will come through the worn compressor by using the same oil that compression gases contaminates from many awesome miles on the engine.
    Replace your air dryer desiccant can to prove me right or wrong, and get a wiff of the first few purges.
