Oilers

Unknown

Hi all, as you may know I am new to the group and new to Hudson super 6s. My 28 oiler on top of the engine drains out too quickly, in fact one empties in about 15 minutes. I took the cover off but didn't find any flow adjustment. Can anyone advise me how to set oil flow. I have been looking for an engine schematic without success; if you know where to get one, I would be a happy camper. Thanks in advance for your help
