I haven't seen oil inside my gauge, but I have seen the nut on the oil hard
line on the back of the gauge loosen and allow drops of oil to hang on the
bottom of the nut. What alerted me to this was that the gauge oil pressure
needle began to vibrate wildly. When the nut loosened up, it allowed the air
to bleed out of the line. Air in the line is apparently necessary to dampen
the pressure pulses in the system. Unscrewing the nut completely, pulling the
line out of the gauge, then replacing it solved the vibrating needle problem.
Check the security of the nut. If you do have oil inside the gauge, you need
to send it out.
There is little possibility of the gauge failing completely and the engine
losing oil pressure. The inner diameter of the flex hose from the engine to
oil hard line, and the line itself, is very small. It's enough to transmit
pressure, but not much actual flow of oil.

Subject: [Healeys] Oil in oil/water temp gauge
Good morning,
This morning I tracked a couple of oil spots on my jeans back to the oil
pressure gauge. There's a bit of oil inside the gauge, and the oil is seeping
out.
Can I fix the gauge myself, or do I need to send it out?
Can this wait a few months until the driving season is over? What's the risk
of the gauge failing badly and the engine starting to loose oil pressure?
thanks,
Tom
