Source for Garrett Turbo CBV check valve (and a bit more) 700 1989

My 89 760s turbo spins out of control when given the gas. Replaced the upper long turbo hose that had a small hole, still spins wildly.

The only thing I have found per the FAQs is the red/grey vac valve leading to the intake from the CBV seems to be bad - as it blows easily one way, and slightly less the other - with the 'frup' sound.

SO I am looking for a source for that. Anyone know one? After a search here on the board it looks as if a dealer does not have it.

I did check and make sure the CBV was good, checked the vac hose under the turbo (on the front side) ...BUT, I noted when I put my hand under the turbo where the adjustment rod is, and rev the motor - it does not move at all. ??

Does anything I have mentioned give me a lead to a solution? Anything I am missing, I would love to know.

Oh ..the turbo spins easily and has little side movement when checked by hand.

Thanks so much.
