The weapon is running again :)

Well that's the r back up and running again I do how every have a small issue off a vacuum leak :0 I can hear air coming from around the inlet manifold area she drives smooth on the road but a little miss on idle boost gauage is showin -2 I'm sure it used to show -6-7 any ideas? Cheers cott

check all the little vacuum pipes and covers all round the throttle bodies and the vacuum chamber pot at the rear
sometimes you find splits on underside of pipes so check very closely

Is there anyway to make a pressure tester?

not quite that easy with vacuum as air will escape through bypass on throttle bodies

by the time you booger about trying to make something up you could have found the leak anyway assuming there is one
