Good evening, the primary transmission case of my 1947 Ariel NG 350 is filling up with oil, probably from the engine. What could be the cause? I thought it was the crankshaft ball bearings, but at first glance they seem to be in good condition. Is it possible that there is a problem with the oil ...

Thanks for the advice, I think I'll close the holes and use o-rings from draganfly since the holes are through and you can hear air coming out

Good morning to all the club members, I am restoring the engine of my 1947 Ariel NG 350, I found the screw cap for the intake valve rocker arm regulator with three through holes. I would like to know if it is normal and if so what they are for.
Best regards
