You really want a *flow* of fluid (oil) past a temp sensor, otherwise the surrounding metal will act a heat sink. A collumn of non-moving oil will not conduct heat as well as metal. So you'll be measuring the temp of the metal, not the oil. The tip of a temp sensor must stick into the moving fluid.

Not the case with a pressure sensor, obviously.

Todd,
Thanks. Your picture gives me an idea.   I have a bypass block on the old oil filter location, and it has a port on it that I use to provide oil to the PSRU.  I think I'll try to find a "T" to put in the port, and stick the temp sensor in the other end of the "T".  As I recall I have a 90 degree fitting on the now for the oil line.
 
I though about drilling another hole in the bypass block, but I would have to remove the intake, which requires removing the turbo, just to get it off.  I think that I'll look for a "T" with 1 male and 2 female pipe threads.

That is exactly where I put the sensor.  In that case, I have no idea what my oil temp is.  That's not good.  I'll have to figure out a place to put an oil temp sensor.

Hi Steve;
    Attached is a pic of how I did it. Both plates are aluminium, bottom plate has an elongated hole, while top plate has a matching groove cut in it to eliminate any chance of creating a restriction by blocking passage with the temp sensor. The "T" is used to feed my turbo & psru.
