    Cheers for that Mr S - it's looking like it might not be a lumpy one. It does sound smoother than my old CC variant.

    LOL - I've just got zero spare time atm Jon - We rent a property out which has just been wrecked, I've got a window to fit at mine, the cooper to get finished and sold. It's just not possible atm. Thinking longer term, I will get the GT2860rs repaired, get some work done to get bigger vlaves in a newer head and whack the CC in this block. But this is a few years down the line, I'm just about keeping my head above the £££ line without car stuff atm. But time is just as big an issue.

    Having troubles guys.

    I'm having a problem with a boost leek.

    The boost will build and hold @ 20 - 21 psi, but it takes an age when in 4th or 5th, and it's lost all it's potency.

    I've checked all boost pipes, joints, actuator / controller pipework which all seems acceptable. I thought there may be an issue with the throttle body above the cholk flap, but there is nothing that can leak there, so I pressurised the system from the carb side of things and blanked the turbo inlet. Can't build 1psi of pressure?????

    Any idea's why my turbo may be leaking?

    is it ok to test it that way?

    Without pressure to the far side of the dump valve (from the manifold usually) it would open your dump valve, possibly?
    Could be leaking out of the actuator line from a bleed valve


    Can you smoke test?

    Have you checked the wastegate isn't stuck open a little bit? That would tie up with your symptom.

    OK, I'm not gay, sailor boy, so let's just get that right, and qualify it by not having a dump valve. So that clears that up.

    Wastegate? Surely the cold and hot side are completely isolated from each other? I've checked all vac lines and all hold boost.

    I'm thinking it could be turbo related, but what? If I where to fit a blank to the inlet of the turbo, and applied pressure from the outlet (all compressor side) should that be totally sealed?
    What and how do you smoke test?

    Thanks for trying as always Dave. :ay:

    If I saw a row of pink tents at a freddy mercury tribute weekend, they wouldnt be as camp as you ;)

    Have you confirmed a leak then? I'm just thinking of your symptoms, coming onto boost lazily with no leak would be a classic wastegate open symptom.
    Do you still get compressor surge/wastegate chatter when you lift off? When you have a boost leak of significance that usually changes, or tails off, as boost escapes through the hole. Usually you hear a leak too, when you're on boost.

    With a smoke tester!

    It basically fills the system with smoke, and where there's a leak you see smoke escaping.

    Penny warped on the wastegate ? Looks like it shutting but isnt ? Possible crack around wastegate ?

    I have no retort for such a comment sweet cheeks XXX

    Hmmmm - all great points, I hadn't considered some of those points having been preoccupied with banana monthly, a lubed up special. That aside - Compressor surge is no longer as epic as it once was - I'll have to check to see what's happening in that department next

    I have no access to such equipment - I'm sure I could mock something up though if pushed - we have canned smoke at work.

    Another area to look at.

    Thanks for all your input - I'll take a look at every given opportunity and report back

    All our love Big Gay Andy N Fluff XXX

    go on where was the issue?

    Front of the compressor housing 'was' a small lug which 'blanked' a hole where you can hook up vac line.

    That's blown out!

    Thank fook for that.

    Anyone know what thead it's likely to be?
