[TurboDSM86]

well its a shitty night and i figured id do a boost leak test on my car because it didnt seem to have everything to it..

first i found that the licp was just pissing out air..alright got that fixed

next i found the bov line i had to tee into for my mbc was leaking..alright that problems fixed..

now im up on the intake and i found something i dont know what it is..although i know it is pissing out air..its the little black hole that is below the golf tee and above the tps

here is the picture of where its leaking from..please help or my 330 lb asian friend will eat you...

Are you refering to the BISS (the whole where the screw head is)? If so, there is an O-ring in there that might be damaged. When you pressurize the system, can you put your finger over the hole as it is leaking to make it stop? If so, try to replace the o-ring. Check this for the part number (from vfaq):

You might want to check the o-rings in the throttle body, there are 2 of them. They tend to dry out. Hope some of this helps.
