I've not had any luck with cheap sub 50 dollar boost gauges with electric sensors in the daily driver. Been through two of them in 2 years time. The electric sensor 52mm oil gauge has, knock on wood, been great. I now run a glow shift boost gauge.
Yeah I run the same cheap Chinese boost gauge in my boat for the past 5 years without an issue.
So far the Disco has only gotten glowshift gauges however in the past I've always had good luck with auto meter.
Tee fitting will work, I have done it. I have used the innovate motorsports MTX-D oil temperature and pressure gauge quite a lot as it has programmable alarm (flashing oil pressure numbers or flashing led's for temperature. I use the oil temperature sensor for coolant temperature, works fine. https://www.innovatemotorsports.com/...mperature.html If you have an 03-04 you can use the unused oil cooler port (LS engine oil pressure adapter works), on a 99-02 you can also use the plug higher up. Fits nicely in our new gauge pod.
Yeah I’ll be ordering one of those pods once I’m back to the Disco as my install on the ‘00 wasn’t quite that clean.
And a couple folks mentioned the canister style oil filter. My Jeep has one of those and you guys will laugh at the factory part (not kidding) to be able to take a reading from the year Wrangler it is. The cap for the filter housing is simply drilled and plumbed to where a sender can be screwed in and a pressure reading taken. I just installed in permanently again with Glowshift stuff. I did a T fitting again so I could get oil temp and pressure. Taking that same logic to my current Discos, that sandwich adapter has more than one port and I could do the same thing- temp and pressure- and have it cleanly installed in the Disco. I like in my Jeep I can see both oil and coolant temp and see when and how they parallel or don’t. A nice feature in the Jeep with a telematics application I have for it is that I can put the electric cooling fan into “hyper” mode, which in a 90 second cycle drops the coolant AND oil temp by over 20 degrees F.
It’s extremely useful as it helped me diagnose an oil pump issue in the Jeep. Again, because I like pics:
Here is what I did: On the oil pump cover there are two ports. The upper port is plugged from factory. I moved the factory oil pressure switch into the upper port. In the lower port, where the switch was I installed a pressure sensor with a NPT-M12 adapter. This is the ideal location to measure oil pressure, because it is post filter. Into the oil cooler port, which is plugged from factory too ('04), I installed an oil temperature sensor. To display the values I use Torque Pro (Phone App) via a BT adapter.
