Just tried this again... still can't feel any play, axial or radial.
So when you initially tested for any play within the impeller, you didn’t get any movement at all?UPDATE: The chirping noise was open throttle compressor surge, and the siren noise was a failing turbo bearing. After hearing the turbine blades zipping against the inside of the housing, I pulled the intake off and felt obvious radial play. Turbo replaced at 27kmi.
How soon after your posting of no play did you then find the play - or did the turbo chirping just get louder and more consistent and you just took it to Dealer?
It’s really good Tech for other users as a reference, so any additional info you can add would be great.
You’re lucky the impeller didn’t implode, otherwise your engine would be choking down metal frags and a simple chirping could have been a very costly repair.
I had (2) prior SVO’s years ago... 1 of the SVO’s decided to do a turbo implosion at 65mph... talk about a Spy Hunter-esque smoke screen out back.... LMAO... couldn’t see anything behind me at all but smoke; luckily I was able to limp off before anyone could see who it was blanketing the highway in smoke... Funny thing was, that turbo never made any chirps before letting go, it was just an instant failure.
