Took the bakkie to the agents today:
Compression test OK
Glyco test OK
Pressute test at 1.6 Bar: No external leaks - heater OK, radiator and hoses OK
They then put the truck on a pressure test for 1 hour at 1.6 bar (normal operating pressure 1.1bar) - dropped 5PSI over the hour - re-pumped to 1. Bar and started motor, revved motor - pressure increases as RPM increases, drops again as RPM drops - they reckon I have a hairline crack in the head between water ports... Will be able to tell once had is removed...
I'll get this sorted in the new year, engineering works closed now, so will have to live with it as is for now...
