well if you want to hear your bov, you need to vent it, but when venting your bov your car will backfire, but if you like that and dont want to risk getting fined by the cops leave it as is. as for your exhaust, put a full 3 inch catback with high flow cat and front pipes will remove that restrictiveness of your stnd exhaust. plus id suggest getting a lager FMIC and get some pods in a airbox with some cold air ducting. will make the car feel sweeter to drive

well the bov should vent when you lift your foot after you give it a decent amount of throttle when sitting on the spot. if it doesn't then it may be blocked. if you take the bov off you should be able to push the plunger up with your fingers with a little bit of force.

Andy, you ask a lot of the same questions.

I have some for you.

1.) when you are driving hard and you are boosting, what sound do you hear in between gear changes?

2.) you have HKS SSQV bov yes?

Like this one..

hks_super_bov3.jpg

See on the back where there is a brass fitting.. just below that, right in the middle of the bov, there is an adjustment screw.

If you adjust that ANTI CLOCKWISE (turning it to the left), it will LOOSEN the spring inside.

This will make it easier for the bov to open when you change gears or take your foot off the pedal. So you should be able to hear it more.

BUT, if you loosen it too much, the car might STALL as it is leaking too much air.

ALSO, you will NOT hear the noise by just revving your engine in neutral. Because it does not make boost in neutral.

Only when you are driving.

    • My thought is if you were just moving it forward and the upstream geometry remained the same, then no difference at all. But because the current one has the filter direct into the AFM inlet, you effectively have the best chance of a completely symmetric air flow profile upstream, and in, the AFM, whilst the aftermarket inlet thingo has a (small, to be sure) bend between the filter and the AFM. That would bias the flow to the outside of the bend (downstream of the bend) which might well reduce the size of the signal seen by the AFM, for the same total flow rate. Having said that: If you're proposing to make your inlet look like a hybrid of your existing one and the aftermarket one, such that there is no bend where the filter is clamped on... then I say it will be just fine. If there is going to be such a bend, then, if you can align the insertion of the AFM blade such that it is at right angles to the plane of the bend, then there is a better than even chance that the centreline velocity where the blade is will remain more or less the same, and the velocity will just be a little faster to the outside of that, and just a little slower to the inside. **This is not professional investment advice and you should consult a suitably qualified ouija board, tea leaves or the intestines of a goat for more accurate prognostication.
    • Hi Tao, Thanks for your reply.  It's been a while and I managed to get the valve stem seals replaced with the head on the car.  Unfortunately this didn't solve my issue, the car still smokes a lot after idling (to be honest during idle you can see a bit of blue smoke from the exhaust), same after deceleration. I will try disconnecting the valve cover breathers, do I leave the PCV valve in? By engine oil drain pipe, do you mean the turbo oil drain?
    • What about if you just give it direct 12v and earth?
    • Hi guys . Can someone help me  I bought an Android screen for my Nissan fuga but it won't turn on   
    • My guesstimate, with no real numbers to back it up, is it won't effect it greatly at all.its not a huge change in position, and I can't see the air flow changing from in turbulence that much based on distance, and what's in front of it. Johnny and Brad may have some more numbers to share from experience though.
