After reading the artical in the tech section of this forum for fittin bov's where the recerc valve's are i thought before buying bov's i'd see what would happen if i removed and blocked up the plumb back hose from my recerc vavles so they vent to atmo. After doing this the car wouldn't run smoothly and would stall! Is this because of the O2 sensors? and if i fit bovs in this location will it do the same thing? Cheers Josh
Stock recircs Will not run properly as blow off valves as they almost always vent or suck air through the recirculation hole (even when there is not a pressure diffence between the vacuum nipple and the possitive pressure inlet).
