Well, Bob, I have opened up a water temp/oil pressure gauge but it was more
than 25 years ago and I don't remember the details. I think it's easy enough
to open it yourself and clean it out before reassembling it, if you are careful
with it. There are Bourdon tubes inside that make the needles move and the
works are kind of fragile, so be careful.
Removing the gauge from the car is a major pain because of that ether tube for
the water temp, but after it's out you can have a go at opening it or sending
it off for professional repair.
I don't quite see why a leak at the nut would put oil inside the gauge. You
may have a small crack somewhere, perhaps the Bourdon tube for the oil. That
would require sending it off.

Hi Steve:
20 years ago after I got my BJ8 back from a shop, who restored the car, while
driving down the road oil squired out on to my pants from a loose fitting on
the oil line. Going back to the shop they just tighten the nut. I have good
oil pressure, but, all ways have oil residue in the gauge. Ideas on how to
clean the gauge before installing the engine trans etc. in the fall?
