I plan to install an oil pressure gauge. I read a guide on how to install the gauge that tells me I need a:

3/8 BSPT Male to 1/8 NPT Female Reducer

to go from the oil pressure bung on the side of the engine block, which is this weird 3/8 BSPT size. To the standard 1/8 NPT size you typically see on oil pressure gauge sensor cables.
I can't find one of these adapters anywhere and all the links I've found are old as hell and lead nowhere.

Can anybody provide me with a link to order one?

You need this to remote mount the sensor. The vibration of direct mounting will quickly kill most aftermarket sensors.

 

 

Mitsubishi makes an adapter that turns the banjo bolts connecting the oil cooler to the block into a pressure and temperature setup. I believe that the parts come with sensors already integrated.

 

I Don't see how the oil cooler banjo's would be an effective place to measure pressure, the flow through them is effected by the thermostat. Also, oil temp should be measure in the pan. The drain plug is large to be drilled/tapped for 1/8" NPT for a temp sensor.

 

I couldn't find the actual Ralliart P/N's, but here is the set I was talking about from Arnside. I assume those are aftermarket, but they might be the real thing. I don't remember the Mitsubishi parts being red, though.

I agree with this, with proven data. I had my oil temp sensor in the same location as my oil pressure sensor (filter housing) and it would barely ever get over 160f and then I moved it to the pan (MAP oil pan) and the temps in the oil pan where 30-40F higher and it goes above 200F on a 70* day, like normal.

 

If you pull oil out the dipstick, like I do, then a temperature sensor on the drain bolt is no big deal. I cannot remember the last time I actually undid that thing. So much easier and cleaner than doing it the old fashioned way.

 

Even if you do pull the drain plug, just unplug the sensor..

 

Not sure you meant to reply to me. I have the MAP pan so there is an extra NPT bung you can swap for a sensor, independent of the drain plug.
