Most likely Buna cylinder base O rings. They'll get hard if the motor sees too much heat. Need to use Viton.

Pro tip check the dates on the last post before you reply, necothreading is common if you don't.

You'll find there's a serious load of knowledgeable folk in here willing to help, get the usual run of clueless smart asses too but you'll figure them out easy enough.

Welcome to crew.

Or the the oil return dowels are leaking since those are the 2 locations. I’ve found good results with the SnS oring dowel set up #500-0385
