Heater Valve fix - gushes coolant

[BadAss95-530i]

hello all,
This may be normal in which case forget it.

I did the heater valve trick (tapping) yesterday. As per Bruno's instructions on his website, i first loosened the 6 torx screws. I clearly heard it clicking as the knob was adjusted by the wife. The possible problem= with each click, coolant gushed out from under the body of the valve above hoses. To me this makes sense (after all, i loosened the screws keeping the two parts together!)...but no mention of loosing coolant doing this trick was ever made so im worried something is up.

1.Anyone care to chime in on if that was normal?

2. Also, the wife told me right away that she felt heat after doing the trick, but now it feels like the air flow is weaker than ever. Is there somethign in there I may have screwed up to effect that?

Thanks
