zd 30 turbo leaking air

[joshofrog]

hi guys i recently put in a dawes valve and blocked my egr and have developed an air noise when just holding my speed goes away when accelerating. i sprayed soapy water around the engine bay and the turbo seems to be blowing bubbles from where the actuator goes down to the turbo . any thoughts on whats going on here ??

So is it coming from the actuator itself or the lever arm on the turbo??
Either way it's a leak and needs fixing..

Did you fit a needle valve with the dawes?

Find that strange being vacuum operated

I think you need some gauges if you haven't already so you can monitor what's going on.
Boost and EGT

Where and how did you block the EGR???

This.... your turbo is vacuum controlled. So if its blowing bubbles, somethings not right.

i did fit a needle valve and boost gauge all seems to be working fine and car drives fine i blocked egr on intake side when i started it after blocking it the motor sort of sneezed then stalled but has run fine since just with this funny noise

air seems to be coming frim the arm where it goes in to control the vanes (i think thats how it works)

I wonder if that's normal..
But could you be hearing the needle valve??
It would be not working as much when cruzing compared to full throttle..
