Locations I selected for Omori oil temperature and pressure senders.

For my oil temperature sender I chose the same location that STR8OUT did for his oil pressure sender. There is a solid plug in the oil gallery just below the compressor outlet and the intake (near the PCV) that can be removed and a Subaru Gallery Plug with a 1/8 PT hole tapped into it - P/N 11024AA210.

Another angle looking from the front of the car.

My Omori oil pressure sender comes with a remote mount hose. I chose to mount this in the same location as the stock oil pressure idiot light switch is. There is already a 1/8 PT gallery plug in that location. I chose this location so that when I get a T fitting I can put both my after market and idiot light switch in this same location.

This location is just behind and to the left of the alternator as you look at the front of the car. Please note to always disconnect the battery ground whenever you remove the alternator hot wire.

How good are the readings from the temperature gauge? I was worried that mounting on top of the engine wouldn't give me accurate readings since the probe wouldn't be sumberged in the oil.

The readings are dead on with the stock Lameco oil gauge temp. gauge.

At 90 celsius in the oil pan the oil gallery is reading 195 fahrenheit.

Under pressure the temperature sender is submerged.

No problems with the oil temp sender not being grounded? Or does it not need to be....

I am almost positive it has its own ground wire through the gauge connection. If it was a type that had to be through the sender, why wouldn't it be? It is in direct contact with the gallery bushing which is in direct contact with the block. It is working fine so must be grounded.
