Oil Pressure?

[Rocket Ron]

Has anyone fitted an oil pressure gauge to a Z3m>
?
Regards Ron Hi!Having successfully (if only temporary) fitted the gauge & sender It is reading 34 on tickover,
Does anyone know what it should be?

I've seen a few people add one to their existing car. @PeterJ has added a whole set of extra dials to his centre console, but not sure if that includes Oil Pressure.

I'll see if I can find a picture...

Hi How do I remove the existing Gauges ?

The gauges are held in place with a threaded sleeve. To remove them press on the glass of the gauge to hold it in place and reach around the console with the other hand. The sleeve is knurled kind of like the lid of a glass jar to make it easy to grab and twist. Just unscrew it all the way and the gauge will slide easily out the front of the console. Then you can disconnect the wire and set the gauge aside. In order to keep the connections straight I reconnected the gauge behind the console. Once the console was removed I disconnected the gauge subharness and set it aside with all gauges attached.
The lighter / power plug just uses blade connectors. Just pull them off.

Wow! Many thanks Ron

Hi Again Many thanks ! Any Idea what the oil pressure should be? I suppose the readout depends on the Gauge & sender but @ least now I have a ball park figure !
Being strictly old school I do like an oil pressure gauge ! Regards Ron & if nobody is using it I will in future sign off as Rocket Ron.!

Hi Ron, are you permanently removing gauges? If so, I'm interested in putting them in my car if for sale? You can PM if you don't feel you want to answer in this thead. JIM

HI it will only be the outside temperature gauge that I will remove permanently if its any use to you say a Fiver plus postage Regards Rocket Ron.

Hi Rocket Ron, just checked the manual: oil pressure, idle 0.5 bar- 7psi
Regulated pressure (elevated engine speed): 4 cyl-4.3-or +0.2 or 63 -or-+3psi
6 cyl- 4.0 bar or 59 psi
Hope this helps, JIM

Hi Rocket, just got your message, I don't think my car has that, I'll check with previous owner. If no then I will take it. Later JIM

Wow! Many thanks Ron

I fitted oil pressure, oil Tempertaure, Water temperature (OEM is gauge too heavily buffered) & Air Fuel ratio meter. Seems I cannot post pictures because files to big & the only way I know to reduce file size is to upload to facebook & then save ! Anyway, you will quickly see from the oil pressure gauge that the pressure at a given RPM dramatically varies with engine temperature. the Oil pressure on my M52B28 at 750 RPM idle varies from about 18 to 40 psi depending on temperature & about 40 to 60psi at higher rpm. It is interesting that when driving the car from cold, the OEM in dash water temperature reaches normal before the enigine is upto operating temperature which is not good in my opinion. The real water temperature takes a lot longer to come up & the oil temperature temperature even longer. I do not stress my engine until the oil temperature is up to about 90C

I will try to post some pics on a new thread

Hi Peterj, I think that because your motor is aluminium with iron sleeves it does take longer to warm as heat is dissipated so quickly. Please correct me if anyone else has a theory on this, HT? JIM

Peter, I can help with the photo issue, it is easy!
get the picture up on the screen, then click on the Windows Icon bottom left side and type 'snipping tool'. This will allow you to drag the mouse [click and hold] to select whatever part or all of the picture you want. then save. The new picture is a jpg and will be very small in Mb/Kb. you can even use the snipping tool to draw on the snip you just did! Look in the options. The new snip picture will be the very very very small.
