Where to Install Oil Temperature Sensor

[Brookshire my]

What is the most common/practical place to install a oil temperature sensor on a 1.7?

It comes with a temperature sensor, I think, you may have to buy a taco plate for the 1.7

Down in the sump where the oil sits. The "taco plate" is the round sump plate that is held in with two bolts, as opposed to the one with a single bolt that also holds in the oil screen. The OEM ones are two piece, there is one plate that holds the sender and a cover plate. Aftermarket ones are available as well.

This thread on 914world shows pictures of the stock parts.

LN Engineering also sells an aftermarket one.

No second taco plate on this car. I assume a aftermarket sump that holds more oil. I will find out next week when I change oil just how much it holds. Also no oil temperature gauge on the dash. Just a low pressure light.

The taco plate is above that aftermarket oil sump, on the engine case itself. you'll have to remove that sump to get to it.

Or you can weld/drill/tap a boss on that sump for the sensor.

Regardless, it'll have to come off.

Is he reselling Rich's (or vice versa)?

Don't know. It's possible, but that looks like a relatively easy part to turn up on a lathe so maybe not.

I have no oil temperature gauge or sensor since this 914 was stripped by someone in the past to make it into a track car. I have no center console or the console gauge set. Also all heater hoses and heater related parts taken out. No big deal as I live on the Texas Gulf Coast.

So you're starting from nothing, evidently.

The sensor should be in the sump, where the oil sits. You may be able to find one that replaces the drain plug on your deep sump. Depending on your typical oil level, you might be able to remove the deep sump, install the "taco plate" and sender, and re-install the sump. Or you may need to drill and tap a hole in the deep sump for a sender. (Don't do it on the bottom and take away even more ground clearance! Try on the front or rear.)

You'll need a gauge that matches the sender's range. Aftermarket gauges and senders are pretty plentiful; there are a number of gauge mounting options ranging from inside the combo gauge to on or under the dash to replacing the ash tray to on the A pillar. You'll need a wire that goes from the sender to the gauge. Depending on what year your 914 is, and how modified the wiring harness has been, there may already be a green/black wire in the main harness that you can connect to. The gauge will need switched power and possibly ground, and an illumination light which will usually be powered by the black/blue wires behind the dash.

Quite a few things to figure out, and some fabrication to be done.

Great information! Thank you.

I added a capillary tube affair a few years ago, works great. I drilled/tapped the case on the lower/front portion of the case and cemented it together with a two part epoxy.
