- Cooling system was flushed out pretty good... and stop leak still holding after a week.

How is this different symptom wise than before you used the stop-leak?

You should be able to check the cap with your pressure tester.

oh sorry... no more blowing pressure off through the radiator cap now. Appears to be less white exhaust smoke (hard to tell). Combustion leak tester showed slight discoloration before and none after, so it must have been a pretty small leak. Most noticeable is no more rough idle at startup in the morning and no more fault codes being set (misfire cyl 3 & 4, Peake code F19 : F0, F1).

cap was replaced
