Hi guys I got a new oil temp guage installed and just wondered if someone can comment on the temp I am getting out of it.

Temp sticks at 140F / 60c on idle when warm.. and drops to 100F / 37c on my journey to work, always moving and a bit of the A120 dual carrige way... I know its been cold but is this ok, shouldnt the oil be hotter than 37c?

And just for a total curve ball, I stuck the sensor in the sump bung... could the air under the car be effecting the reading?

done the same with oil temp gauge. had the engine running with the car stationary. rad was kicking in so engine was warm. i'm getting a reading about 40c. Know the gauge works as i've tried it with hot water. Can't be a very good place to take a temp reading.

Also to go back to oil pressures. mine's reading about 95 psi on cold idle and about 40 psi on warm idle. although you hold the revs at about 2500 rpm and the pressure increase to about 85psi with warm oil. Would be hard to believe that we could both have faulty pressure gauges or pump relief valves

I would have thought that 60c is cold too to be honest. I was told 70c is warm and 80ish is upto temp!

Your oil temp wants to be upward of 80 deg C.
What type of guage are you using?
Is it accurate?
Guages like SPA need to be set to the type of probe in use.
It may take 10 miles plus of running before your oil starts to warm properly.
On cold winter days I can do a run of nearly 20 miles at speeds up to 70 mph and the oil is still not fully warm.

im using racetech capilary gauges. In the process of now tapping into the oil gallery port underneath I/C bloody tight for space. will let know how it goes

Stick the probe/sender in a beaker of boiling water or a boiling kettle even and check that the guage reads 100 C or thereabouts.

Pretty sure the readings are down to where the probe is positioned in the sump plug..... above no3 under the i/c will give much better constant readings.

The probe has to be long enough to sit in the oil flow to provide an accurate reading.

remotely fitted it above no.3 piston again did not get a proper reading. As harvey said the key is good oil flow which by remotely fitting you don't get as the oil flows to a dead end.
I can't fit it directly above no.3 piston as my cappilary sender is 3/8bsp and there's no room for an adaptor.

need to look at fitting it directly into the oil flow in the sump. Only problem i can see is that sender hang a bit low. Need to get it sorted though!!!!!

The last couple I have fitted were done in conjunction with an oil change. The sump was removed and the sender was brazed in place on the side of the sump, 2 or 3" back from and a little higher than the drain bung. I also know that sump temperature is typically 5-10 deg C less than the temperature above #3. Fitting on a remote lead etc is not an option.
Get the sender out and put it in a boiling kettle. That will answer one question.
Also, depending on the sender thread and diameter, you may be able to use a sandwich plate with already tapped holes to take oil pressure and temperature probes. I may have one here and will send photos of it if that will help. Send your e-mail address.

managed to get a fitting to replace the sump plug. fitted temp sender and tried it and hooooray it works a treat!!!
