Hi peeps need a bit of advice on a turbo as I have no experience.
Got a fault with the turbo unit on my mrs's Astra cdti. It's making an awful screaming noise at off boost conditions. It's def the turbo cos if I open he wastegate it stops. However I have noticed a potential fault.
Well I think it is so this is what I'm checking, the hot and cold side of the tubby dint seem to be directly connected I can hold the cold compressor wheel so it doesn't move but the hot side still appears to move as tho the shaft is either broke or has a slipping device built in
My Clio tubby isn't like this both turbines are locked together.
The turbo is still making some boost. I'm going to drop it off the car tomorrow and take a look, just want to know if that is normal operation on some turbos, i
It's a garret unit
Thanks
