I figured it would be a quick 10 min job to swap a bad crank sensor on my sons car. It sits above the oil filter and can’t really be seen from above or below the car. How bad can one bolt be?

The bolt came right out but this tiny sensor refused to budge. I picked at it for almost an hour and broke it into tiny pieces before I gave up and let my son try it.

After an hour of fun watching him using a digital inspection camera to see around the filter boss and grabbing it with vice grips while snapping off more little bits he finally managed to pop its internal steel core out. Then it was easy enough to put a concrete screw down the center hole and pop it out.

the new one took 5 seconds to install

 

Now the ECU is happy again… 10 points to whoever can tell me what engine this is just from the scope trace.

The simplest things are sometimes the most aggravating……..
