First of all thank for the quick help.
I replaced the o ring like @Calum mentioned. Still leaking.
Also checked for the crankcase breather but couldn't find the plastic stub.
I uploaded some pictures can you guys tell me were I can find the breather?

Ignore the o ring next to the tacho meter cable, its an old one.
Thank you guys
