What have you done to your MSP today?

i should think with the IM off, it should be pretty easy to fish the starter out ect. id looked pretty spacious actually, when i put the p5 motor in. maybe next weekend ill get to pulling all that. i do remember two of the IM bolts being less than fun trying to remove.
easier to install after i deleted the VTCS though.

Sounds like you might have some FOD on the turbine wheel. I know this is gojng to be a pain but I think you're gonna need to take the turbo off again. Sorry. I thought you just had an oil leak issue. You'll be looking at the turbine wheel for this. The image at the very bottom of the page. You should be able to see the blade edges without taking the housing off. Just shine a good flashlight into the turbine out and look down the housing contour at the portions of the blades that are broken in the image.

The only other issue you might be having is that the spring in the actiator is shot and the exhaust air is just pushing it open. But that's unlikely since you've already checked it.

Let me know what you find.

I don't mind removing the turbo again, I just want it to make boost. (Full story of the car so we are on the same page: Purchased car with blown motor, 110k. Swapped JY motor and reinstalled turbo, car runs great no vac leaks and very smooth just will not push boost. Ebay fmic kit and relocated maf with no apparent leaks.) There was oil in the hot pipe and a small pool in the intake when I first pulled it because it would not build boost.

You can tell from the pics the turbine wheel is not damaged, the blades and the housing are perfect. I can try another wastegate actuator but it definitely has a good amount of tension on the wg flap, it takes some force to move it. What can cause a turbo to blow oil and not build boost? I assume it would be the seals inside the center cartridge behind the compressor wheel. Is there anything else it could be?

I would like to believe this turbo is ok, PO said the car pushed 8psi all day but I purchased it from another guy who only had it long enough to put 1k miles on it (and blow it up). Hard to believe the turbo and motor could both be bad. No shrapnel made it through the engine when the #1 rod snapped, the head and manifolds were fine so no particles could have damaged the turbine wheel as far as I know.

Does anyone else have a weird harmonic noise from the rear tires/wheels while driving? This is my second MSP and I have the same problem with both cars. It's a constant hummmmm, quiet, hummmmm, quiet. Just curious if anyone has had the same problem and knows how to fix it.

Just buy another CHRA. I know its about $690.00 but I think its worth it, that way u start fresh with a new turbo Nd don't have to worry about it breaking down in the future.

I can rebuild for about $100 or go used for $250. Not spending that much unless I am upgrading to a larger turbo.

Did he replace the bearing cartridge and all, or just the O-rings?

Not sure, the rebuild kits are from $150-200 and they are not garrett parts. I don't know if I should trust potentially inferior parts going into a turbo. And it would need to be balanced before being installed on the car.

Replaced piston rings and seals, bearings were fine.
