Uh... of course.  Leaking at any pressure (usually higher means more leaky)
is why you replace your heater/valve/o-ring.

But it is not an inherent design flaw (like that radiator shop said) that
causes the heater core to act all Sybil on you.  If heater leaks, replace.
Leak fixed.  Done.  No need to worry about variable pressure leakage.
Perhaps we could call this VPL Syndrome...

I have had leaks at higher pressures that never showed at lower.

I have had leaks that showed at lower temps that didnšt show at higher
temps. (almost always at hose connection points)

But I have never had a leak in a core that showed at a lower pressure and
disappeared with higher pressure.  Usually become very obvious at higher
pressure.  Sometimes even spectacularly obvious.
