pulling the O2 sensor out of the exhaust stream with that right angled adapter seems very odd to me
I wouldn't run that if it was me
any reason why the sensor can't screw in normally?

do you have the actual hole sizes between the two parts? as I wonder how much of the oil pressure loss at high rpm is down to leakage ?
I'm assuming that the later part has the smaller hole ?
