Normally in the 1-3 psi range. We do commonly see these engines making roughly .7 psi when warm.

Thanks. I was below 1 psi after a good 15 min run. Will keep a eye in it.
A lot depends on how-far below 1 psi. If the thermostat is fully open, the pressure may be quite low until it recovers/closes (note that splitting a couple tenths off of 1 psi isn't what we're talking about here).
.3 to .4: now that's a problem for sure.
