Leak at oil cooler

Hell Again Gents
Looking at my oil cooler from the bottom up there is a plug like you would find on the tranny fill or the tranny fording plug.
It looks to be leaking a little oil past it what should I expect when I pull this plug to teflon tape and dope it dill I get a deluge of oil oil over the place or just a small drip that a few rags can handle.
Thanks Jerry

Small drip as long as it has sat over night. I think that is the oil sampling port.

Got any pics? The oil cooler can not be seen as it is under the cover you are calling the cooler. The cover houses the coolant.

No I cant get pics sorry I have sizeing issues on this site
there is oil on the cover but I cant see 100% around it could there be oil comming from a higher point?
Thanks Jerry

If the oil cooler leaked it would show up in the coolant. Pull the plug and use thread sealant and see if it clears. If there was any leakage around the housing it will be coolant.

It may be the oil cooler bypass valve.
