No boost/ Whinin Noise Idles fine

[T-MA71]

Well today i got the turbo back on and the whine isn't AS loud. I have an exhaust leak now though. I'm going to have to helicoil the head and replace all the hardware. I'm going to be replacing the turbo too. It has ~220k miles on it and never been rebuilt Hope to buy one this weekend.

I'll post again after i replace everything to see if the whine goes away.

A guy i met at a car show told me that the whining noise could possibly come from the bearings in the turbo. So i just replaced the turbo with a newer low mileage one.. So pretty much my turbo was trash hah. But months later got Rodknock

Was there any notable marks on the turbo Indicating that it was trash?
A lot of movement on the fans maby?

Yea the shaft had a lot of play in it. It seemed like it rubbed the housing a little bit. But the actual fins showed no damage. Just alot of sided to side and back to front play. But either way, i replaced the turbo and the car ran great afterwords. Is this something thats happening to your car?

Do you have a wideband?

Do you have a wideband?

Me? No, mine was was 100% stock except the fact that i was running 12psi with a manual boost controller.

Hum i was thinking of something but nvm, pull the accordion hose off and check for shaft play.

Same stuff happend to my car.
0PSI Boost/ Pressur from the turbo. and a high whining noise.

Have taken a look at the turbo, and the there is some movement on the shaft, but i cant see any defects. Also i have disconnected the oil and water to the turbo when i checked the shaft on the turbo... Dunno if this makes any different?

Ill go for a new turbo and hope it solve the issue...

Just sound wierd, that there is 0 pressure at all. I would belive it should make aleast some boost.
