acv blockoff question
 

ok so i tried to block off my acv today right, i got RB headers and presilencer, and it has a stud and two holes for screws. so i took it off and put it on and had the screws in the bottom tight, but the nut wont go all the way to the block off plate cuz the threads dont go that far. so i figured id start the car and see what happens, well it died on me, lol, it started and died. im thinking its a vac leak cuz it didnt seal properly but, am i doing something wrong here or what?

You need to remove the studs and replace them with bolts


Or if you want to go ghetto style with it you can stack some washers on the studs before the nuts go on

haha, will the studs just come out, or am i gonna have to work at it to get it out.

Mine came right out with the double nut technique. Vise Grips usually get the job done pretty well also

Just give it a good bath with liquid wrench and get a good clamp with the vicegrips, mine came out without to much trouble. The ACV blockoff plate came with your header right? Mine did along with 3 new bolts for the holes.

If you're unfamiliar with the "double nut technique":

You should have two nuts from the ACV removal... Thread the first one down on the stud, leaving enough room for the SECOND nut to fit on the end of the stud too. Tighten the FIRST nut BACKWARDS into the SECOND nut. Use two wrenches (or whatever) and tighten the two nuts into each-other. This will lock the nuts together on the end of the stud. Put your wrench on the first nut you threaded onto the stud and begin turning it counter-clockwise. Since it's locked on the end, the only thing that will start turning is the stud... You're now offically removing the stud.

After this stud's removed, break the two nuts apart and repeat on the second stud.

Or maybe you already knew how to do this... lol.

^ yeah, then find a couple bolts that have the same threading as the studs and bolt that frikkin' plate on there! Make sure you use some RTV black, or some other high-temp sealant for the block-off plate.

You don't need sealant, just use a gasket. Either get the stock one or make on from gasket paper. Easier, less mess, more reliable. :)
