i have some smoke/vapor that comes out at idle too, especially when the motor is cold. im using the z10 setup. i think its relatively normal. i wouldnt worry unless u have bad compression or high leakdown

One of the by products of combustion is water.

It looks like water vapor, I wouldn't have any worries.

It's completely normal. Hot crankcase gases hitting cooler air = vapor
