Let me see if I am reading what you're saying correctly....

When you tied the valve cover vents into the IAC, you were puffing blue smoke? Once you let them vent to atmosphere, it went away?

Right now that is how I have my valve cover vents (venting to atmosphere..) but I'd like to tie them into the intake with an oil seperator inline with a 1-way check valve.
