The RTA and EPA are ****s. They can practically defect you for ANYTHING which isnt stock... You could have a plumb back and they can send you a EPA defect saying "Change Non Standard BOV". Its bullsh*t, and as for open atmosphere BOVs, they act like its venting poison... its just AIR!!!! sucking from under the bonnet and straight back into the bonnet without even going through the engine.. what a load of crap. I am lucky enough to never been defected but the previous owner of the car was *being smart ass too*. I really want to get an engineering slip for my car so I will have no worries about getting defect... I just hope all my mods will pass with an easy going mechanic engineer *think of import Lamborghini’s & other High end cars and they're twin turbos, big fat exhausts, roaring rich engines, & truck wide tyres, they're fine because they're Stock and Engineered that way....
My mate got defect for a broken tail light *lol, just like in the movies*, anyway the cops asked if they could pop the bonnet but they would have to sign something to do so... I thought this sounded quite odd that the cops couldnt pop his bonnet without getting permission, sorta like a search warrant for a house... I duno, i wasnt there, maybe its bullshit, but it doesnt sound right to me....
