right then iv been trying to fit a dump valve to my 1.7 tdi isuzu astra, iv put it all on but cant find the right vacuum pipe to put it on.
is it posable with this engine or do i have to get one of those boxes iv seen on ebay if yes i wont bother?
iv put my spare dump valve off my escort rs turbo on it and it all fits fine
i tryed fiting it to the egr but soon as it comes on boost the d valve opens itself and keeps hissing no matter what the rev loosing all pressure
i know alot of people dont like d valves but mine is quite laggy through the gears so i thought i would give it a go plus it hasnt cost me anything
any advise on JUST fitting a d valve to my car would be great
