wrong about ignition module heat sink compound...it was there when it was new! 700

posted by  someone claiming to be JohnB on  Mon Mar 24 05:42 CST 2003 [RELATED]

I've replaced at least two of them, one an 87 760T, another 90 740T. Both replacements had some type of dielectric/conductive paste between the IC and the heat sink. One of the reasons the new IC's come with a new heat sink, apparently.

Pressure washing the engine indiscriminately will apparently clear the compound from the IC/heat sink. The IC can then overheat/thermal runaway, leading to intermittent engine cutout. Shut the engine off, let it cool or freeze-spray the ignition module and it may work again, or may be fried.
