Default fuel leak at engine crankshaft ball bearing

Hi all
I'm french and it's nice to find an active forum to talk about 1/16 nitro generation (vulcan, Nb16...)
i've a vulcan since some month
all is ok with it but i've since the beginning a fuel leak on engine at level of crankshaft ball bearing (see attyached picture)

do you have same experience with your own vulcan ?
is is a new ball bearing better ?
i use fuel 16% nitro -
i ve made a good break in and engine seems very powerfull , nice starter, nice accelrations.

I'm sorry for my english language, i hope you understand my questions

Have a nice day

Hi,

The Toki engine is known to blow fuel/oil thru the main bearing...It is a high pressure engine., this is normal.
