anybody tried this location for a sender/sensor?

 

Yah, that's what I did. Works fine.

 

what did you use there? Oil pressure? Where did you mount the oil temp? In an oil cooler?

 

I used a pair of banjo bolts that were drilled and tapped with 1/8th NPT fittings. For temp I used a normally used for EGT in the bolt on the front cover (before the oil coolers in the flow path) and connected it to an so I could read/display it with an Arduino and a 20x4 LCD display. For pressure I used a that outputs 0-4.5V connected to the banjo bolt where the cooled oil re-enters the engine. Again, connected to my Arduino.
