Knock Sensor
I am putting back together my 91 F150 302 / E4OD, after replacing the head gasket. When doing the tear down, I found the KNOCK SENSOR was melted in half. I now have two pieces and the wires inside the sensor are melted. And my local auto parts store doesn't have a listing for the knock sensor.
My question is do I need this sensor or is there a way to put everything back together without it? And the truck still run without much problems
?

You don't need it, if the truck ran fine without before you found it destroyed. This has been covered many times. Mine is the same way. I left it in and put wire caps on the wires from the harness. If you do a search, this was cover several months ago and was lengthy in Posts. General consesnus was you don't need it, but for $35 or so $$$'s you can get a new one. Need to get th right color code from the sensor if possible IIRC.

So I am going to put a plug in the hole in the block and cap the wiring as you suggested! Thanks for all your help, it's greatly appreciated.

Knock sensor retards timing 4 degrees if senses knocking. As long as you are not expierencing any knock you should be fine. The trucks are the only 5.0's that used the knock sensor. I am guessing because of the potential for knocking with heavy loads.
