If it is at the intercooler piping or any pipe connection where a clamp goes, unbolt the clamp move the coupler around a bit to reseat it, then retighten the clamp. If it is at the throttle body, move the throttle cam, and if the tone changes hit up Aby@mil.spec and replace your throttle body shaft seals. If the leak is at your BOV we need to know which BOV you have. Since you have an VIII the stock BOV is plastic and is probably leaking from there... if it is leaking from the BOV your best bet is to purchase a new BOV of your choice... most people will go with a IX metal BOV if running less than 28 PSI...

i am guessing the leak is coming from the bov because i was messing around with the stock bov to do something and after i put the stock bov back it started leaking but how can you check where the leak is coming from?

Build one find the leak for sure. Don’t guess if you have one you may have more. The stock 8 BOV leaks but it leaks into the intake track so it should not affect drivability. Also how much boost are you running how do you know you have a leak? Any relevant mods?

dhonibhai

no i have no relevant mods...i only have a greddy tic exhaust.....and i know i have a boost leak cuz when the turbo spools the car starts bogging

That sounds like an over rich condition build the tool hook it up and see where the whistle comes from. I hope you have a boost leak b/c the alternative is knock or timing or...

That doesn't sound like a boost leak. You should get the car diagnosed to see what the issue is.

+1 Bogging when spooling is not caused by a boost leak... check the MAF sensor plug... happen to me once it wasnt tight and car bogged every time a gassed higher then 3k

ya it bogs for a while and than it is fine sometimes but at times it jus starts bogs
