The workshop manual states:
So yours is 4 times the minimum pressure at idle. “A Land Rover immobilized is a moral defeat for the driver and bad publicity for the vehicle, […] it's up to you to do justice to your Land Rover!” - Land Rover Driving Technique. -- 2009 2.4 Puma Defender 90 SW 1979 Land Rover Series 3 88" Last edited by o4dn on 22nd Nov 2018 8:11am.

Cold idle is anything between 5 & 7 bar depending on the ambient temperature.
Hot idle is 1.6 bar  --

Yes - I found those values in the manual, but have not been able to find what the “typical range” is. |

Are these values on your truck or where did you get these values from? |

these are on my 90, they've been like that since I bought it new in 2010.
I have a Madman EMS installed, so I can see the oil pressure, coolant temp, transfer box temp, and EGT in real time. Click image to enlarge -- 2010 Defender Puma 90 + BAS remap + Alive IC + Slickshift + Ashcroft ATB rear 2015 Range Rover Sport V8 Supercharged

The EMS2 gauge that I installed is what started my questions. I pulled the sensor to put the mechanical gauge on and I was under the impression that 5 bar was too high as Madman now supplies a 0-5 bar sensor as standard unit.

5 bar for cold idle is not that high, I've seen mine go up to 7 in winter (when I still had the old 10 bar gauge).
what is important is hot idle, just make sure it's between 1.4 and 1.7, every engine will be slightly different, but as long as it's above 1.2-1.3, you're fine. Set your alarm for 1.2 bar, so that if the engine loses oil, you have ample warning before a catastrophic seizure. -- 2010 Defender Puma 90 + BAS remap + Alive IC + Slickshift + Ashcroft ATB rear 2015 Range Rover Sport V8 Supercharged

Thanks- good to know, I thought I might be over analyzing this.

IIRC, these are my other alarms:
EGT: 650C Coolant temp: 101C Transfer Box temp: 110C -- 2010 Defender Puma 90 + BAS remap + Alive IC + Slickshift + Ashcroft ATB rear 2015 Range Rover Sport V8 Supercharged

Oil Pressure started out at 4.5 bar and when engine was warmed up it settled into 2+ bar.
Thanks for the information. |

2+ bar at hot idle seems high to me --

There is a difference of approx. 0.4 barg for warm oil (>50°C) depending on viscosity. If I use 10W oils, I land at 1.6barg and with 0W oils the pressure corresponds to the manual specification.

Oil pressure will be highly dependent on oil viscosity, ambient temps (when car is cold) and engine rpm.
I'm also using a Madman gauge, and was going nuts at the beginning as I was seeing very different values, and couldn't figure out what was normal. When the car is cold in summer, I see over 4.5 bar at idle. In winter (cold car) I often see over 5.5-6.5 bar at idle. The only comparable (and reliable) values are when the car is warm, and at idle: With the recommended oil-spec I see 1.6-1.7 bar. Also noteworthy is that I had an intermittent issue with the sensor, that was going to full-scale, and reading maximum values over 10bar... even when the car was off  Changed sensor fixed that. |
