Puffing smoke

by Pete Olson

While plugged in and building up air pressure, my Mastercraft air compressor started puffing huge clouds of black smoke. Why is this ?

Pete, where is the smoke coming from?

If the compressor is running for a long time, it is possible that oil from the sump is burning, and, if you have a bad intake valve, it could exit there.

Not knowing the model, the operating conditions (how long running at a time), or where it's coming from when this smoke occurs makes it pretty hard to help you diagnose the problem. More info would help.
