Is not working not had a proper look yet but had a quick scan over and can't see any boost pipes that have come off, had the dump valve off aswell and is operating fine so its not that. Anyone else with this engine had this problem? Thanks.

check the vacuum pipe that comes off the dump valve as this is what ur dump valve runs off if theres no vacuum when the throttles closed then it wont work not sure where its connected to but u should be able to trace it

Yeah checked this pipe to see if any jubilee clips have come loose on that pipe, are these liable to splitting? Looks like im gonna have to take it all off over the weekend..

check if theres any vacuum on the pipe when the engines running if not then may have a split pipe. if there is vacuum then it looks like ur dump valves fooked
