Hello. when I blow air oo-o.5 bar in the control line on the wastegate blows air out of vent pipes. must it? or is my Waste Gate Diaphragm leaking?
Sincerely, john |

Shims need to be there so spring doesn't wear into aluminum.

If it leaks constantly or doesn't hold pressure, you're right = leaking. And that is most probably what it is.
But, if it holds pressure, even at a low level, and then discharges it could be a worn out spring. So, when rebuilding the diaphram get a new spring JIC. |

I am not sure but it should be along the lines of if you can feel it then there is too much slop, I would take it to a machine shop and check the runout and then press in a new guide and ream/fit it.
