AERA is _ The _ engine rebuilders definitive source for tech info. Note near the top of page 2 they are using 50 PSI to test for coolant leaks on a 15 L diesel.

Thanks for the info from a professional. I am more confident than ever that the head from jy will hold up. I did not remove it from the junk car, someone removed and abandoned it after seeing the cracks. It's either he was missing out or my lucky day. We will see.
