My motor is finally in my zr2 im trying to get it popped off this week but im struggling on the steam vent stuff. Im running my stock 02 blazer radiator and resevoir so i would like to verify if teeing into the heater return hose is the correct place to run the steam vent that comes off of the throttle body.
I read this somewhere but it seems like there would still be pressure in the system...

correct me if im completely wrong, thanks in advance.
