Throw it away and replace it with a new turbo. Or find a good shop to rebuild it, or have you rebuilt it before? When you mention cheaper, all I think of is it's going to last till after the first start up. This is not a part you use the cheapest stuff you can find. Although it is only a 7.3, You could save even more going to U-Pull it, They have plenty of them.
