There's a LOT of weird data here ....
... first, I don't think the OP ever described the car other than saying: "a customer Boxster".
We don't know if it was a dual-row or a single-row bearing car.
I'm going to assume that it was a single-row bearing because a DOF cannot be installed with dual-row bearing which has both seals.
In order for the bearing to fit it needs to be shaved down to the edge of the circlip and once that happens the seal cannot stay in place.
Here are two dual-row IMS bearings.
The one on the right is the OEM bearing
The one on the left is an OEM bearing that has been shaved-to-size for the DOF.
As you can see, it is shaved down to the edge of the circlip channel.

Mistake (BIG) number 1 ... having installed the DOF Kit with the outer seal intact.
The DOF was just going to cool down the race but oil was never going to get into the balls.
Whomever did the installation did not read the supplied instructions which clearly state that the bearings outer seal needs to be removed before the DOF flange is installed.
Another assumption I will make is that this engine was rebuilt, or at least had the head(s) worked on before the DOF was installed.
When you have a newly rebuilt engine (no oil in the galleys) you have to have the head plug in place so that the pump can build up pressure and fill all of the oil passages including those to the lifters, cams, etc.
Installing the DOF line is like having the plug open, therefore oil pressure won't build up, or will build up very slowly.
If the OP would have re-connected the DOF oil line after the galleys filled up the engine would have been quiet. and that would have ended the issue.
If the OP would have called the supplier, we would have guided him though the correct steps so that he could have corrected the car's issues at minimal cost to his customer.
Instead, he chose to not to do so, publishing a lot of mis-information on the forums and sourcing a competitor's part at his customer's expense. :(
All of this is just very weird.
Happy Porscheing,
Pedro
