I've got my hands on a single wire vdo temp sensor. From what I've read in other posts, it screws into the taco plate, and I'm going to need some gaskets. If my motor didn't come from the factory with a temp sensor, do I need to figure out a way to drill and tap this thing into the taco plate, or is there a good source for 73+ taco plates?

Thanks,
Alex

that reminds me ...

whatever happened to the billet taco plate project?

I'm having some programming issues with my CNC mill

Here's a Taco Plate listed on eBay; Tidyboy is selling it.

The VDub guys use a sensor that sticks in the oil dipstick hole.....pretty ez install.

There's another one that replaces the drain plug.

James....does that one work like the head temp sensor/thermocouple?

both terrible ideas*..

*I gotta say that so I increase my chances of selling my billet parts when I get around to making them, hahahaha

It works just like the oil temp sender. It's a thermistor, varying resistance with temp. I have one on my Type 3, as it doesn't have a taco plate. As far as I know, other than the threads on the plug and the length, it's no different that the 914 sensor.

The 914 CHT is also a thermistor, just a higher temp range. The Westach/VDO aftermarket CHT ring-around-the-spark-plug senders are thermocouples, which generate a very weak voltage based on temp.
