Hi guys,

Hopefully someone can shed some light on this.

Started noticing white smoking coming out of my the rear intake cone on startup, and revving.

There is nothing coming out of the front cone.

Anyone got an idea what could be causing this?

Isn't that pressurized air coming from the turbos where the BOV feeds back into the intake tube? It's going to dump the pressure from the turbos after you rev up the motor and then let off the gas....to dump pressure when you let off of the throttle.

When pressurized air goes to normal atmospheric pressure, you're going to see some white "fog" when moisture forms. No different than opening the air valve on and air compressor......

Yea I had initally thought that, removed the BOV connection and still saw the same.

Potentially its coming from the PCV system since it's only on the rear inlet.
