Had the Turbo on my Zafira welded about 3 weeks ago and now it feels like the Turbo ain't working.
When i had the Turbo welded i had to set the boost back up as i had to split the turbo from the manifold so set it to wot regal recomended for phase 1.
After i set it up my bus felt much stronger and boost was pretty much straight away but now the boost doesn't kick in now till about 3.5rpm.
Looking at the Actuator i only have about 1-2 threads showing at the end and was wondering if there should be more showing.
When i did the Turbo i took off the Dump Valve as it was making the bus drive like crap. When i first did it i could hear the Turbo chattering on gear changes but now i can hardly hear it.
I was thinking that i may need check the boost again and up the boost up if needs be as it seems that way
