bov question

[Supraboy89]

i dont want to sound like a dumbass or anything just want to know if they make a atmosphearic bov that will only release intake pressure and not draw a vaccume back through it like a diverter valve will at idle. the reason i ask is because i have only worked with the ones that will stay open when the car is idleing. also has anyone used a diverter/ blow off valve on their car like this one for a jetta

If you get a Synapse Sychronic, there is an adaptor that they make for theirs to fit onto the bov to keep it from sucking in air at idle. Search for it on streetfire, there's a vid on there with one installed.
