Wastegate?? 930 3,3 -78

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.
