CM2250 intake/exhaust leak results analysis

[JMBT]

Hello, I just replaced my exhaust manifold gaskets, so I thought it a good time to try Rawze’s exhaust/intake test using an air bladder in the turbine outlet and one in the compressor intake. I made a valve to pressurize the system through the turbo temp sensor hole. I set my shop air for 10psi. I then got out the soap bottle and found two exhaust clamps leaking and reseated them to fix the leaks.
However my system never would pressurize at the 10psi?? Is this normal? This being the first time I have tried this test I don’t know. I could always hear air moving and the shop air tank would eventually drain down and kick on the air compressor. I was at a loss as to where the air was going as there were no external leaks. Then I took off the oilfill cap and I could feel air coming out. Is this ok?? Or should I be planning a new turbo soon?? Thanks in advance.
