On an 870 it's very easy to convert to the compressor to naturally aspirated. Remove the air compressor intake and block the port with a threaded plug or cut the tube off and put a quarter in the nut and thread it back on.
Then take your silicone tube go to your local auto parts store and get a crankcase breather filter and replace yearly. By doing this you're solving the soot problem and charge air pressure won't be getting in the crankcase depending on the compressors condition.. Only side effect is the compressor will be noisy..
