What is your oil pressure at idle with a warmed up engine with hot oil?
For those of you with oil pressure gauges. Please post your oil pressure at idle with a engine that has its oil up to temp.

Curious myself on what oil port, what thread pitch, what electric sending unit and gauge combo’s folks have.

this is adapter you will need.
Toyota to Aftermarket Oil Pressure Gauge Adapter
this is where you will want that adapter
FSM specs for oil pressure
I just have a test one
Engine Oil Pressure Test Kit
once I have verified the pressure I will remove it. you can leave this one on the truck and just tuck it over by the battery and drive around. then check pressure whenever you want.

What did you do with the factory sending unit when you connected the aftermarket one in it’s place?
This is a 1/8” BSP thread T.

Better description on this one of it containing both NPT for aftermarket sender and BSP for OEM sender.

The China seller add uses some of the same images as the US seller add.

like I posted above
1/8" National Pipe Thread to 1/8" British Standard Pipe
5vz has BSP and most aftermarket stuff in US is NPT
I have the yota shop one and it works fine. it's a bit tight in that spot but it does fit.

Bump to the top. Anyone with an oil pressure gauge installed on the 3.4l?

I have one. And to answer the OPs question at idle I see 4 to 6 lbs of pressure. Rubbing down the highway at 2500 rpm it's around 45 or 50 and max I've seen it was 80 at redline. My sensor is installed in the port that's lower down on the block than the factory pressure switch.
Coming from the world of small block Chevy's where they typically have 30 to 40 psi at idle the super low pressure freaked me out but the fsm specs 4 lbs as normal and the warning light comes on at 2lbs

This is for my 3rz, not what you need but maybe informative.
14 psi at hot idle RPM and 70 psi at 3,000 RPM.
These may not be exact as I bought a cheap gauge. I used the harbour freight cheapie oil pressure tester while replacing the sender due to dripping oil.

Black798,
Would you tell us what sensor/gauge you installed?
I see lots on the net but it seems to be $30 China stuff or a jump to $200 race stuff.
A little leery of the China stuff, afraid the sensor may spring a leak, and the sensors look big.
