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.
