Re: PSI for block testing
A friend gave me the basic motor I have in my truck because a guy that was going to buy it pressure tested it at 165 psi and blew a pea sized hole on the #5 intake valve-guide pocket. The fellow brought the motor back and told my friend what he had done. My friend was so mad he rolled the motor out on to the ground and left it there for about two years before he gave it to me. Fortunately I was able to engineer a repair that worked.
Pressure testing is good if not carried to extremes.
