hello every one.
I have an 02 reg astra SRi-T.
Was driving home last night and the turbo suddenly got very very loud!
There is no smoke coming out of the exhaust..but no boost either.
I have not checked before, but the dump valve is open, when i take the vacuum hose off it closes, but as soon as it is attached again, it opens fully. (where should it sit when its on idle?)
It sounds like a very loud vacuum cleaner, which i think is the sound of the turbo winding up.
I have a boost gauge and that spools up to "0" and no further..so its obviously not showing any turbo boost.
What could this be?
Would it be a loose pipe? Ive left it at home today and jumped on the train to work..im hoping its the hose out of the bottom of the turbo...gonna have a look tonight, but couldnt see any other hoses loose when i was looking last night.
Your help/comments would be uch appreciated. Thanks
