bleed nipples not big enough. need to be about 10mm internal diameter iirc.
get your mate with the welder to weld up the original holes for iacv an re drill 2 holes at back beside act sensor somewhere. if you have a pillar drill you could drill out 2 bolts so as you are just left with a threaded tube. tap holes in back of inlet to suit. screw tubes in and put a nut on them to tighten up. jobs a good un. or if poss get him just to weld on 2 alloy stubs.
