I do the same thing on my friend's yacht diesel engine too. Prime the oil pump using starter and we have true mechanical gauge in engine room to witness oil pressure building up.
The flybridge helm station get electrical engine oil pressure gauge.
So, if anyone thinks oil priming using starter is a waste of time and must use special pressurized oil pump, its your choice.
=============
For M157, Xentry does not allow Compression Test feature . Xentry compression test is actually similar to Relative Compression test, but with piston speed data, instead of
battery current data for those doing Relative Compression test
So u need to unplug all 8 injector wires...duggghh and clear up DTC after the test. Damn.

Hmmm is it possible to get this done using Launch? Curious. I ... Uh... Haven't got Xentry yet....
Maybe you try to see the menu on the Launch.
Me only dare to use Xentry for Compression Test, because one of the requirement ( when all ready ) is to fully open throttle ( accelerator pedal 100% pedal to metal ) and press brake.
It won't be fun if engine suddenly turn ON and our accelerator pedal at 100% ....when and if such feature went bad on 3rd party scanner.
