Alright, So I got a GT28r sitting outside on my work bench right now, and I got an issue. 1. I can not get the exhaust side of the housing loose to clock it, it is really stuck.

2. One of the coolant lines fittings is stuck in the turbo and it just spins freely, won't loosen or tighten.

am I doing something wrong here? I have a feeling that the threads are messed up somehow, but wanted to ask before I decided I needed a new turbo..
