It’s the on-going saga of my MX-6. The other day I drilled and tapped a hole for the second temperature sensor. The J-Spec motor I put in the car only had a port for 1 sensor while the ’93 A-Spec motor requires two. The work was pretty straight forward, but since I’d never tapped a screw hole before I had to practice on the old J-Spec throttle body. Once confident, I proceeded to drill the hole in the radiator return block on the motor. All went smoothly except the pictures!

The sensor hole is drilled out to the right size, ready for tapping:

The finished product! No leaks and the engine runs great!
