Header tank cap tend to fail on these. Thermostat wont open before boiling point at atmospheric pressure, that’s for sure. Cap ensures it remains pressurised system.

Hmm.

And I’m self learned, not professional trained, I guess I do above the average professional diagnostician.

Don’t mind me saying I cannot follow your diagnostic strategy. I would follow other route, but guess it’s down to personal choice.

No doubt this will be fixed soon.

Here’s the link, apparently you don’t need to go crazy on it, system should build no pressure whatsoever during cranking, if headgasket is in good shape.

See south main auto youtube test for blown headgasket using pico and wps500x.

Ben, please allow me to open a discussion about insulation testing. Having a battery of 400V and doing insulation testing at 500V. Without doubt, with any system is subjected to an insulation test, makers have taken into account some extra margin, however, never in my career of more than 20 years, w...

Knorr bremse uses 5 V TI CAN in some of their modules.

Maybe someone can make head and tails of these, if indeed applicable:
