Head temp sensor above or below the spark plug washer?

Which way is better?

Mount between the plug and washer and I suppose you'd get the best sealing but the sensor spins with the plug.

Mount between the washer and the head and sealing isn't as good but the sensor is easily removed.

I did mine below the washer... It would have been a pain to remove the plugs with the sender above the washer.

I thought that was for wiping my hands when I was done with the install!

Actually, I can't believe I missed that.

I also removed the washer.
In addition I used some copper grease to act as a kind of thermal interface... Helps the heat transfer more easily... So a more accurate/faster responding reading.

I just tore down my 2lt. TI that the OP did not remove the washer on the plug also, it was the only chamber that the exhaust valve was not totally shot, but only due to a weak spark (well the spark was goods just too far inside the threads) JR

Can someone provide a link to a picture of this temp sensor? Is it worth having on a 914?

Its the thermocouple for a CHT gauge.

EVERY aircooled car on the road needs a CHT gauge!

..and ideally 4 sensors: one under every spark plug!.. with a dash 4-way switch.
