[s-cars] Oil leak after clutch replacement. Is it "new design" oil seal?

[Ivan Demkovitch]

Folks,
 
I didn't take it back apart yet to see where leak coming from. But I'm pretty sure it's engine oil. 
 
I had new desing main seal flange installed. The one with rubber molded into it, where paper gasket not needed anymore.
Anyway, now I remember reading on a list(?!) about same problem people had. Was it a leak through M6 bolts that hold flange to the engine block?
 
It's a lot of oil...
 
Thanks,
Ivan
