glow plug / injector harness damaged

Hi guys. I'm new to the forum. Just picked up the truck ('95, F350 w/ 7.3l) so I thought I'd learn as much as I can about it.
We're up in Canada, so cold starting is beginning to be an issue...
I checked the gpr and it's working.
Next I unplugged the harnesses that feed the glow plugs and injectors with power. I noticed that both ends of the plug (ie. the outside pin receptacles) are both all really badly "melted". It looks like it would very hard for there to be any continuity through this connection.
Can anyone tell me if they know: Is this melted condition "normal"? Is it a symptom of a bigger problem? (ie. glow plugs staying on all the time) Where's the best place to get replacement plug ends?
Any other info that you guys (or gals) think is helpful would be much appreciated. The unit is tore apart in my driveway and Mama-Bear is going to want it moved...if you get my drift.
Thankyou, Gord

Valve Cover Gasket Replacement


You have to get a new valve cover gasket. The gasket contains the wiring for the glow plugs and injectors. That is how the wires (on the 95 anyway) get through to the glow plugs and injectors. I bought one at Advance Auto. Auto Zone has them too. You can of course buy from the dealer for twice the money. Not a bad job to replace them and doing both sides is likely a good idea. It solved my very hard start and very rough running problem.
