A good amount of vapor exiting the QT54 crankcase vent.

QT54 Less than a year old.


From day 1 the compressor was expelling vapor or atomized oil out of the crankcase vent. Talked with Quincy and they said it was not abnormal. They sell an exhaust kit that somehow recirculates the vented air from the crankcase. Does this sound right?

I was also told it could be the Quincy oil and a component they have in their oil that is synthetic.

It's for personal use in my garage. It will fill my garage with a fog. I use it for light sandblasting and air tools.

Some Mercedes-Benz were like that.

The re-circulator is doable, but what do they want for it?
