good morning newb.

2 bolts where the bov attaches to the crossover pipe. remove large plumb back hose, remove boost signal hose. Block off plumb back hose. Signal hose can be used for A/M bov. get a metal plate, drill 2 holes to match those on the cross over pipe. and bolt it on with some sort of rubber seal to stop leaks.

Or you can leave it on and make you car a look a little more stock.

I am running 2x BOV's at the moment.. one stock and the aftermarket..because it came as part of my intercooler piping. The Blitz one doesn't open really at all (much stronger spring), so you do need to block the stocker.

Like chef said, some plate metal, some tin snips and a drill should do it. I actually built a blocking plate for the Blitz as blocking the stock one has been known to cause idle problems.

Might put the blitz back on when I am running higher boost and you can actually *hear* it :D

    • So, now all you need to do is connect the 2 or 3x 12v feeds into the unit to permanent 12v, ACC 12V and IGN 12V that you can find in the spot behind the stereo, and the earth, and then it will switch on with the car.
    • Yes then it will turn on but I want the car features to work  
    • 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?
