seen this http://www.youtube.com/watch?v=HRiK2HEA3QQ
and thinking im gna give it a bash.
obv just a case of connecting it in somewhere.
where would be the best place to connect it to maximise its use, ie disconnect MAF and let it run down the tip (sealed of course), checking the boost piping etc to TB then opening the throttle body to check the inlet manifold/PCV system?
-
I seriously need to do this to check where I have a leak!!! Wonder if an old fish tank air pump would work? Need to change my lamberts to hamlets as I don't think a cig would last long enough though. Also would the smoke pass through and out of the turbo if it was coming from there?

Nice bit of DIY diagnostics.
-
gave this a go and wow, was amazed lol.
found this leaking out the inlet manifold.

took manifold off and cleaned the mating surfaces and put back together using instant gasket this time as well.
done smoke test again n looked tight :).
cars idling alot more smoother now and vacuum goes straight down to around -20 In/Hg where it was around -5/-10 before. job done me hopes :)
Had the 17953/P1545/005445 - Throttle Valve Controller: Malfunction code for a bit but i assume thats because the throttle body was off, has since cleared.
Pics of Smoke Tester
Just an old metal coffee tin i found lying around, drilled 2 x 20mm holes and used CTS stuffing glands to secure the pipe that i had.

I just used the brake booster port to inject the smoke, sealed with tape :).

Used a 12v compressor connected to the pipe with a valve thing made air tight.
I just lit some oily rags i had lying around and through them into the tin, worked a treat.

Doesnt pressure-ise the system tho so bit pointless unless its a big leak. Sometimes leaks are there under pressure. And when you think you have 20psi of pressure going through them..

MPG is great now, 38.7 cruising at 70 on the dual carriegeway earlier :)

But it's blowing smoke out of any leak you may have? Mine sounds like a f***ing tank so I guess it will show anyhow :\
