In the process of trying to fix a miss fire, I am at the dealership last night looking at the new crate motor. I looked over the turbo. Looking at the portion that has the 3 bolt flange the cast in divider is cracked. According to GM Tech this is normal since it is on the exhaust side. However my issue is the part obviously would not be acceptable at the engine plant so why would it be okay at this point? Note this is the 11th time it has been in for service for an engine miss fire. Would you want to replace anything that looked damaged let alone something that is????

There was a TSB long ago that addressed the cracks. They happen and have no effect on the vehicle. It is just something that happens to tha casting and it has no effect on the life of the turbo, the car or the emissions.
It is common to have small issues like this that often people never see or know about as it has no effect on the car.
I would not get all that worked up on this as it is not really that big of a deal as it may seem. Over the years I have seen some things that are really scary but are still acceptable and neve fail on most vehicles.
This is something Honeywell will address on the upgrades for a new model and redesign the casting.
There are fatal flaws and there are acceptable flaws and this is the latter. Companies will not spend millions to fix something that will not effect the life or emissons of a vehicle if they don't have to.
Now if these housings were coming appart we would see them replaced. Replacing these really would not change anything but the part on the car and nothing more. It will live as long as the original part anyways. These turbo's have been out long enough and on many different cars to show they are really no issue.
Most turbo issues here have been related to other parts in the system or parts bolted onto the turbo unit and not the unit itself.
Nothing to worry about here just keep moving along.

are we talking about the divider that inside of the exhaust port? if so I have replaced lots of turbos on the dodge products in the 80's and 90's if it was a new turbo the divider was not cracked but if it was a remanufactered unit they where all cracked right out of the box. I was told by the factory that it was a normal for a used turbo to crack in the divider and wouldn't hurt the life or operation of the unit. I do agree that it is somthing that looks like a problem but as far as I could remember they all cracked there.

technical service bulliten related to crack on flange.
These cracks are not uncommon and are considered a normal condition and should NOT be a reason for replacing the turbocharger assembly. The cracks will not affect performance. If the vehicle exhibits driveability concerns or turbocharger DTCs P0299 or P0234 are set, refer to SI and follow the established diagnostics for correction of the customer concern
