WTB: IMS Guardian sensor

[paulofto]

I'm going to experiment with my original sensor by grinding down the hex shoulders a little and then using epoxy to strengthen where the wires exit the sensor. Hopefully this will give it better contact with the sump and give the wires a little more strength. Wrapping the wires with electrical tape should help too. I'll then swap out the current sensor with the 'refurb' at my next oil change and do the epoxy trick on it as well, which won't be until next spring some time because I just did an oil change and put the Boxster into hibernation for the winter.
