does a successfully passed cylinder head pressure test insure you that there will be no coolant leaking into the chamber or ports regardless of operating conditions?
I would say that it would depend on what pressure the cyl head was tested to . What is the normal pressure # to test cyl heads to ,,,,,,,,,,,,,,,,,,very good question ?
For the most part that should ensure a positive seal with the exception of extremely extenuating circumstances (overheating at some point it will leak).
