I took last Friday off to use up the sick days I didn't take this year. So I used that day to run errands and get a couple things done. Replaced the heater blower fan and blower resistor module in my Grand Marquis. Whilst getting those parts, I got another tarp for the Crown Vic, since the top layer/tarp (3 layers of tarp) was coming apart. I peeled all of the tarp off to put the new one underneath them. I discovered that some vermin chewed up a small section of the 3rd layer and used it to make a small nest under the windshield. So I grabbed the vacuum cleaner and cleaned all of that up. I figured since I done that, might as well clean whole cowl and some of the engine compartment. Then for whatever reason, I started pulling plugs and inspecting all the wires. I found a few plugs had some gel form on the electrodes. I have no idea what it is. It looks like vaseline. Does WD-40 gelatinize? That's the only thing I can think of.
I would post pics, but my files are invalid now for whatever reasons.
