it seems at idle i have alot of vapor that comes out of my catch can. im using the endyn setup. have one line on the back of the block going to a top port.the drain on the bottom back to the other port on the back of the block. i also hooked up the valve cover stock port ran to the other top port of the catch can

has anyone had this issue??

 

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

 

welcome to owning a catch can its normal fo sho.

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
