If done correctly it should not leak. Its a very simple low pressure seal. It is however easily damaged.
Put the seal on the pipe and then assemble into the block, not the other way around, otherwise you will likely damage the seal with the edge of the pipe.
Do not ever try to keep the pipe attached to the turbo + manifold and reassemble as a job lot, you will damage the seal.
Either that or you have some old seal, sealant, dirt etc in there.
You also need to ensure the PVC is working correctly, as the vacuum keeps the oil in. Lossen the oil cap and lift it gentle with finger tips and see if you can detect a slight pull on the cap when its close to closed.
If you run extra boost on the track with high rpms you really need a one-way check valve in the big inlet feed pipe as the pressure dump on throttle close will pressurise the block briefly pushing oil out of all the block seals.
