But why did you not put some sealant/black goo instead of the o-ring? WOuld have saved you a lot of hassle, wouldn't it? :-/
It's not that easy, as the area around the stat seal is recessed.
I am also feeling incredibly guilty. I remember late last year I offered to help with this job, and completely forgot about it 
The stat housing has the groove for O-ring and the mating surface in the vee is flat. So, putting the sealant to the housing side and tighten up, why it would not work?
No, I do not admit (yet
) having done this to my car because the aftermarket stat leaked with its own O-ring 
If you want to fill a groove with sealant, rather than an O ring - crack on.
I won't be following suit!
Not saying rather, no! But in my case, as the housing and seal were that poor and did not have the original parts on hand I had no choice... And that's what I meant for the OP also, if it will work it would have saved some hassle

Or am I completely wrong with my "solution"? I know you SHOULD use the correct parts and methods and I also respect them, genuine cam cover gaskets, genuine or Gates belts etc...

bodging is all well and good but i must say when it comes to the coolant or any other sealing system i believe you need to be thourough but i get what your saying with what's to hand i've certainly been in that situation!
