Default where did i go wrong

ok i have a HKS BOV SSQV, it came with a straight pipe with the flange welded on it, i have this flange put onto the IC pipes up by where the Filterbox is then i blocked off the pipe comeing from the 3000 pipe to the air filter hose with a soild metal cylinder, bought a longer hose for the vacume line and ran is from the stock location of what the bypass valve was hooked up to and ran it to the HKS bov. now when im driving it is cutting out like crazy bogging? fuel cut? boost leak somewhere?

if it may be a boost leak where would be some prone spots to look, and also i would like to add that i am venting to the atmosphere and not useing a HKS recirculation kit if anyone needs a picture please ask i will start taking them

leave the stock bov hooked up and have the hks one hooked up separately. if you need to have a 3 prong vacum thing to let you hook two vacum lines to the stock location. i plugged up my bov one time and it ran like shit and wouldn't go past 40 mph. so i would reccomend not plugging it up for some reason it screws everything up.

also block the 3000 pipe and intake pipe separately do not join them

we have that same bov and flange pipe on another car here and the bov is loose which will cause a boost leak, make sure it is not loose "at all" as this will cause cutting

have you done a diagnostic?
you do realise that a diagnostic will tell you what is wrong with your car, it is an extremely useful tool that toyota decided to put in our cars

Unhappy

well i was told at my local performance shop to block off those pipes, im not shur really what they do, but just a good guess is that the 3000 pipe blows air while the other one sucks, i dont see why a diagnostics would be in hand considering there is no check engine light on at all, will it still work even though the light is not on?

its really starting to get worse the exhaust is starting to smell bad to the point of where it is burning my nose when you rev it

errr this is really starting to bug me now, mmm suppra how would you say to seal that loose BOV, i mean i could like maby silicone it or something cause im not planning on driving it anymore till i get this issue fixed. and is this bov an issue since im only running the stock amout of boost im reading maby 7-8psi right now its reading about 3-4psi and then it starts to spudder like crazy

p.s. i also noticed some oil spots on my engine cover dont know what type of oil it is, but i did check my engine oil and it was reading almost nothing and just had it done at my mobile 1 about 1 month ago. so im feeling either its leaking or burning
AHHH i cant have this car die yet.

get some oil in there asap altho it may be too late

you will need to get a thicker o-ring if the bov is loose
just see if you can wiggle it, if so.. it's loose therefore buy a thicker o-ring

yes diagnosis does not always throw a check engine light... you may still have codes stored

most importantly.. block those pipes how i told you, not how you have them
i shall explain

air gets sucked in through the turbo, to the intercooler up to the 3000 pipe meanwhile the turbo is sucking the air that is in the 3000 pipe back through to the turbo due to you having it joined
i.e no air is basically getting to the engine, it is overfueling like a mofo and can't run properly

maybe my drawing will help some
