We all know that over time the potting material used in sealing the crank/cam angle sensor will eventually leak out as a black tar. Well, when I took mine out, more than half of the potting material had already leaked out. I found a new way of permanently repotting it.
Material: Fast curing epoxy putty. I got a tube called Magnum Steel from the Lowes home improvement store. The label states that after thoroughly mixing, the putty will harden in 15 minutes and fully cure in 1 hour.
1) Remove the crank/cam angle sensor. Do this when you are replacing your timing belt and waterpump. It's probably not worth the effort just to get to this one part. Here's what it looks like (sorry for the fuzzy pic.)
2) Clean up all the melted potting material off the sensor.
3) Mix some epoxy putty and start filling the void left behind by the melted potting material.
4) After the expoxy has hardened (approx. 15 min.), sand down all the high spots on the expoxy. I just rubbed the whole sensor assembly, with the epoxy side facing down, on the concrete floor of my garage. Here' what it looks like.
5) Clean it up. Wipe it down. Reinstall.
