Is it possible to rig up an oil temperature gauge using a T-piece from the oil pressure sender?

Don't see why not...the temperature reading is relative anyway...the main thing is to get an indication of engine temperature.

repco sell a peice to join 2 hoses togther with a speco sender unit in the middle in mind, i can back this up because i just did the oil lines in the celica, only problem is i am guessing that the most sensitive piont of the sender is the tip and the tip sits about an inch away from the main flow

I wouldn't have thought a sender in the pressure line would have any flow at all....so will only read by conduction.
Jai if you're out there, where does yours send from?

I wouldn't fancy putting an oil temp gauge off the pressure gauge... You won't be getting an accurate reading of the oil temp...

You need to be reading the mean temp in the gearbox (sump) if you want an accurate indication...

For max economy and power many sources I've read recommend running your oil at around 100 deg C. This will keep your oil "clean" by boiling off all the combustion products and moisture that would otherwise contaminate your oil. Running too low (on an otherwise healthy motor) will cause that sludge in your oil cap to form... unfortunately it will also be present in your motor... Running too high and the oil film on all your internal components can become too thin then hot spots and consequently wear can occur...

here's an article which made perfect sense to me if you want any further info...

I've seen a few Nb cars with the fins on center front of the sump filed off and a hole drilled and tapped to accept a temp sender. This would be the best and only way I would do it... if I wanted an oil temp gauge

sorry, i always had the picture of putting it in between the oil out let and the oil filter

The most common problem with Minis is boiling there little heads off....thats where you get the first indication of trouble...if you are lucky....the volume of oil in the sump is likely to mask the upper cylinder lubricant temperature purely by cooling the hot oil with its cooling fins, air flow etc.

I agree with miniobsessed (sump plug). I tried putting the sender unit in the oil cooler hose (cooper s) and got hardly any reading at all :oops: But maybe the electric guages are not as good as capillary ones :?:

I put my sender in on a T-piece between the cooler, and the filter housing. And yes it gives readings. At the moment I'm running it with a water temp sender, which gives (when engine is fully warmed up) readings in the red. But I found at a wrecker the correct sender for my guage. My guage is from a Range Rover btw and the correct sender will be going in next week when I have the time.

But I agree with the above. But my car ain't a race car so the oil temp gauge is there for looks, not for accurate readings.

I've got an oil cooler fitted to the Cooper as standard, so I got a digital temperature gauge from Jaycar for 30 dollars. They come with a probe fitted to a meter of light flexible cable, so I fitted the probe into one of the fins on the oil cooler. It slides in with an interference fit nicely. The temperature is alittle lower I believe than actual temp because of the flow of air over the cooler, but it works a treat and gives me a very good idea of what really is going on - Like you don't actually need an oil cooler on the road for one....it takes about 20 minutes for the oil to come up to full temp with an oil cooler.

Bit late catching onto this thread, but ...

Minispares sell a sump plug oil temperature adaptor. Will be using this to hook up an oil temp. gauge but only as a diagnostic, not for permanent hookup as it's a bad point of failure for oil if it blows out :)

Put one of these into the line going to the oil cooler?
