Was driving enthusiatically last week, and while on full boost @3k ish rpm (~25/30psi in 3rd) i was greeted by a sound resembling a burst in a pipe. Was like a burst of pressure being released 'ppsshhh'
Now, when i plant my foot, it makes a noise that i can only describe as.. errr.. someone moaning.. 'nooooooo' in a shrill high pitched noise in a geordie accent
:roll: , only as it approaches 15psi. Up until then at light throttle it is fine - no noise.
It's not the turbo. Next to no play, either radial or axial float.
It's not the D seal before all the eager beavers chime in.
I'm thinking it COULD be the inlet manifold gasket blowing?
It COULD also be (most likely?) a split in the turbo - intercooler pipe? As the noise it makes sounds like air reverbing through an opening on full boost.
Any opinions please?
Cheers.
