Technical hissing/rattling sound on acceleration
Those figures seem healthy enough however a turbo with blown oil seals on the induction side won't necessarily cause a drop in boost pressure.
If you do have a boost leak anywhere it will be from the area that the oil is leaking.
One trick I used to diagnose my turbo was to undo the boost inlet hose from the top of the engine on the intake manifold, then get someone to rev the engine to 2.5k and look for oil spray. You must take care to clean the system of all oil before you try this test or you will see oil regardless.

Hi, Msted89. Does the blocked DPF can also causing the oil excessive in the intake?
