How do you pressure test a diesel cylinder head?
To do a pressure test, block off coolant passage ports and injector ports. Put the head completely under water at engine operating temperature and apply pressure to the water jackets for about half an hour. You will see air bubbles if there is a leak.
Why do you need a pressure test on a cylinder head?
Usually a warped head lets gases into the coolant but if you’ve checked that the head is level, allowing the head gasket to seal correctly, then a pressure test is needed to see if there is a leak. Packard is right in that the machine is pretty simple, that is why I’d like to see if I can’t make my own.

Is there a way to test if head gaskets are blown?
Is there a definitive way to test whether head gaskets in most engines are blown, without actually reaching for the gaskets themselves (at which point you might as well go ahead and replace them) assuming that the engine is overheating and that all the components of the cooling system are checked positive…
How is an aluminum head is pressure tested for cracks?
Head gasket, thermostat, any ports that flow water. This procedure is usually done after the head has been checked for warp. Once that is done the head is placed in the pressure testing fixture. Next the proper test plate is selected from the stack. This plate fits this head. See how it covers all the water ports on the head deck.

Usually a warped head lets gases into the coolant but if you’ve checked that the head is level, allowing the head gasket to seal correctly, then a pressure test is needed to see if there is a leak.
What kind of tests are done for pressure in the head?
Medical history and physical exam including a neurological exam to test senses, balance and mental status Spinal tap (also called lumbar puncture), which measures the pressure of cerebrospinal fluid Computed tomography (CT) scan, the gold standard imaging test, creates a series of cross-sectional X-ray images of the head and brain
