That's a good idea, Kev. When I had my oil pressure guage installed, I
had an smaller diameter adapter screwed into the block. I could
certainly "see" what was going on better. You may be able to do the same
thing with a standard 12 x 1.5 mm bolt and a jam nut?

One difference between NPT threads and the metric threads on our oil
pressure gauges is that NPT threads are tapered whereas ours are not. I
think this is good because it greatly reduces the chance of cracking the
case at the fitting.

Talcum powder (or any other readily available powder) might help ID the
leak, too.

What if you were to plug the hole with some threaded rod, or some sort

general area, while running the bike.

Thanks for the help, Greg and Keith. I sure wish the
problem would be a leaky sensor, but it was leaking
with the old one in, too, so perhaps that's not the
problem. Keith, were you able to see the oil actually
leaking out of the sensor when the engine was running?
It's pretty hard to get a good look at the sensor with
the tank on. I guess with some longer fuel line I
could mount the tank remotely. I am afraid that Greg's
suggestion, a crack, may be the culprit. I may have
over-tightened the sensor and cracked the casting. I
didn't strip the threads, though. Looking at the
outside of the casting that the sensor screws into, I
cannot see any cracks, but when I remove the sensor
and look at the surface taht the crush washer sits on,
there seems to be a jagged hairline. I don't know if
that is a mark from the casting or if it is a crack.
Any ideas on how I can determine if it is actually a
crack?

Thanks!
