    Worth checking it then as they need a service from time to time... what spring is in it?

    Leave the green in if you have it... stiffer spring will make it worse... Forge sell service kits and if you have an early 007p then get a kit with the new revision of piston that has the o-ring on it...

    I'll get the kit and hopefully the damage to the dv isn't too bad

    Cheers Tuffty I looked it up and I'll order it now, was thinking of replacing the dv altogether but the cost has gone up a bit

    Ok after months of enduring this horrible fluttering noise I had a proper look and found this [​IMG]

    I think a mechanic has bodged the pcv valve breather pipe with tape causing it to rip and cause a vac leak I ordered a new breather pipe and the car sounds much better plus it pulls better to! Case closed!

    i have the exact same noise, serviced the forge 007p dv yesterday and its still there, can only assume i have leak some where, i have the bits to remove sai, and simplify the pcv but not mechanically minded enough to fit, cant find any where local that smoke tests,
