im missing som piece off my 1j that goes on the stock turbo pipes which is suppose to be connected to vacuum. i see that part on many 1jz but i have no clue what it is or if i need. it. the vacuum hose that it connects to also keeps my idle kinda high. whenever i plug it up then the idle goes down. my best guess at it is that it might b where the stock BOV goes? i have no idea really. if it is can i just plug up that hole and use my aftermarket BOV?
