Hi read lots about this on the great web site, I know its the blocking of the Vac pipe that is causing it. When blocked Duck sound, unplug sound goes away, what I want to know is it ok to put a fuel filter to act as a air filter on the end of the pipe that would have been plugged to the by pass EGR blanking plate, or must it be blocked.

Thanks for quick reply hd3, will go for option 2, will also put a bit of pipe from entry to ext of bypassed solenoid to keep it clean, incase I need to go back. Cheers Glenn
