Please...... Thanks

you'll need a "Taco" plate that has the threads for the sender and (preferably) the right sender for your gauge.
either post a WTB in the classifieds or call up the usual parts places ...

If you dont want to have a temp sender hanging under the car, you could do it the hard way,

a T fitting on the pressure sensor location.

Use a remote pressure sensor adapter,

then use a M10x1 temp unit.

I went the super cheap way:
by an aftermarket water temp sender and gauge at the auto parts store
At first I had it in a tee fitting next to the distributor where the oil pressure is picked up, then I moved it to the "taco" plate under the motor. It did not fit the hole in the plate, of course, so I drilled out the hole first to get a tight fit and JB welded it into place. Its been there a couple of years, reading temperature

The bug guys also have the super cheap oil temp gauge that replaces the dipstick.

youll get a lower or false reading this way according to aircooled.net

i agree with A-Aron, the readings won't be correct unless you use the factory location.
Not all 914s came with a temp-sender, so you'll need to get a Taco-Plate that has the correctly angled bung for the sending unit.

Quite correct, my mistake.

I should have mentioned that. However, knowing the readings are low does not make false readings, just lower.

It also should be noted that most VDO gauges are way off anyway and need to be calibrated.

Here is a decent link with a pic of the taco plate.

Im not sure on the crush washer use on the plate. I have always
heard to omit the washer.

Yeah, I used a long thin water temperature probe (.75" after the treaded part, 3/16" dia) SunTune, I think?
If you orientate the tee so that the tip of the probe is down into the oil passage at the the pressure reading point, it works O.K. The pressure tap doesn't care where it reads. I think this picks up oil temp between the pump and cooler. I would show low oil temperature until the pressure dropped, telling me the bypass valve had closed and I was reading the temperature of the oil as it went into the cooler. I wrapped a bit of pipe insulation around the tee.

It seems to me the readings didn't change a whole lot when I later moved the probe to the Taco Plate, though they did come up sooner.
