Should there be thermal paste on the ICM for TBI engines?

There is supposed to be a dielectric lube/paste on the bottom of the ignition module where it mounts against the base of the dizzy.

When I had installed a new distributor, the paste that GM had put under the module kind of looked like white frosting, and another time when doing just the module, the included lube just looked like petroleum jelly or dielectric grease.

Thermal paste is used to allow effective heat transfer from an object to it's cooler. Most commonly used in computers to allow the heat from the chips to pass into the heatsinks more efficiently. For automotive applications it's not needed since your not using heatsinks. Your actually probably going to be using some sort of dielectric grease which inhibits moisture from entering and corroding the connections.

On a side note thermal paste is actually a form of liquidized silver so don't allow much skin contact or you'll get Argyria Wink
