Hi,

This can happen when the wrong compressor oil is used. Or when compressor oil is mixed.

Even if you used the correct type of oil, if it is mixed with another brand/type, then foaming and white milky oil can occur.

This can also happen if there's a lot of water in the compressor oil. The water comes from condensation and happens most often with compressors that don't run very much.

This can also be the cause of the smoke coming out of the inlet valve!

Hope this helps!
