WTB: IMS Guardian sensor

[clickman]

I only need the sensor but if someone has the whole package they want to get rid of let me know.

I'm on my second sensor now. The first one leaked and also became frayed where the wires enter the sensor. Flat6Innovations sold me a new sensor for $99.00 USD. It has also begun to fray at the sensor. This despite securing the wires with zip ties.

We are working on a run of IMSG Sensors now. They'll be done in 3-4 weeks.

As for the fraying, if the wires can move too freely under the car, the fraying can occur. You may try electrical tape the wires to the body of the sensor, so the fray point moved further up the wires. This should not be necessary, though.

Yeah, mine frayed too, to the point of leaking. I've tried tying the wire down better and caulking it at every oil change, but it doesn't last for long. It sucks to have to worry about dripping oil out of your fancy Porsche onto your friends' driveways! I'm tempted to forget the whole thing and go back to the magnet only...

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.

Securing the wire to the sensor with a cable tie might be the best bet. If the wire is free for the turbulent air under the car to move it around, then it can fray at the point where it goes into the sensor. Putting a small bend with not much radius in the wire, then cable tying the wire around the sensor will reduce the amount of travel the wire has.

I see that all of you guys in the thread are Canadian. I can help but think that the wires may be hitting frost humps in the road, or something is leading to this. When testing the IMSG in Alberta I did contact a frost hump outside of Calgary and the wire was damaged, along with the front suspension, the headers and the crankcase.

We have no problem working with anyone on a replacement sensor. We are making a new run of them now and maybe I'll try making some with wires existing he bottom of the plug.

I ended up trying three different sensors and they all leaked. I over torqued the first one; the second two, no. It was a PITA. I've since had the IMSB replaced, and when that work was done, abandoned the Guardian. It was good for a little peace of mind, but the sensor seeped oil from day 1.
