    Ok thanks, would that not cause an error when doing the pedal test though? Or do you think its working, but just the plastic seal is split?

    Grey I take it you mean line off vac box to re-circ valve?

    normally it doesn't cause fault codes, and yeh the rubber diaphragm splits. Everyone fits uprated ones, either the forge or the cheaper (and practically identical) ebay version: http://www.ebay.co.uk/itm/ASTRA-CORS...item3a7df306f9

    no it wouldnt cause a error code, and yes it is worth while doing this replacement of re-circ valve. A friend of mine has done 56,000 on original turbo and re-circ valve he had the flutter sound so we replaced this valve for a forged one, it turned out nothing was wrong with original re-circ valve and vac line was off vac box.

    Ok guys cool, another noob question (sorry about this!) would you guys recommend a blanking plate, or the one way return valve...or nothing at all?

    My car still did it with a direct route and cone, only went when I had it mapped!

    Who ever maps it if they read knock readings etc they will be able to tell if a vac hose is off... If they look lol who is mapping it? Excuse me asking

    Its Shark performance remapping it mate. They are new to the Vauxhall scene but are very well known with VAG remapping. I trust them 100%, but just to be safe I will be getting a forge re-circ valve and a few silicone hoses. Thanks again for your help!!
