Oil leak
I finally got around to having a look at where my slight oil leak is coming from. Looks like it's coming from the original oil pressure switch. As per the photo it's dry closest to the engine block however it looks wet where the plug side is, could this be leaking from there.
I might have also found the culprit to my lowish oil pressure. I took the T out and found a bit of junk stuck in their, blew it out, put it back together, started, oil pressure little better don't really know till I give it a good run.

Unusual for the actual sender unit to leak but looks to me like that's what is happening .

Not all that uncommon for the sender unit to leak. The bakelite section goes hard and brittle from the years on engine heat and eventually oil leaks through where it seals in the metal housing.
I got some switches still mate, but you have a Supershit Auto near by. They will have one.

Job done and no more leak.
Doesn't look like it's done anything for the oil pressure.

For the oil pressure, it's better not to rely on the stock(or even aftermarket) gauge.
It's always better to fit an external meter gauge and confirm it. Yours have a T, so I'm guessing there is
an aftermarket oil pressure gauge fitted. If both stock & aftermarket gauge are showing as low oil pressure, then
it might have low oil pressure, but I wouldn't try anything big to fix the oil pressure issue,
until I confirm with an external oil pressure meter.
Mine has been showing low oil pressure since the beginning of time and the oil pressure suddenly sprung back
after I took the oil pressure sender out and cleaned it with carby cleaner and pressurized air.
The tiny hole that the oil goes through to put pressure on the spring mechanism inside the sender unit get
clogged up with gunk eventually. Instead of buying a new one for $120, I cleaned the old one and put it back, as good
as new. The other possible issue is the electrical connection/resistance. Sender's body itself is the negative(in mine).
Lot can happen with a weak earth connection.
