I forgot when we did the engine work on the 425, I took some pictures with my camera phone....
they didn't come out that good, but eh, better then nothing.
Its hard to see, but the heads/rockers are gunked up quite a bit.... I dunno, I have seen worse, but it is the worst of my 3 cars...it can't be good, but the 425 dosn't seem to care.
My father said it is probably from lack of regular oil changes over the years and just general heat build up, the bottom of the valve covers were really bad, though I cleaned them up nice with the parts cleaner.
I bet being owned by an old lady in FL for the majority of the cars life, it was just driven to the store and stuff.... oil never had time to heat up, and this is exactly what happens with moisture/acid are left in the oil and stuff.... running an engine without it getting up to operating temp... ah well... one day this car will have a hefty 500
The engine runs fine, starts easy, idles really smooth.... you would think its a new engine. Plenty of power for what it is etc...
Does all that gunk really bother anything? or it just kinda sits there and minds its own business. I know I am not thinking twice about driving it from NY to FL in about a week.
The valley was somewhat clean, lifters, cam etc... just the upper parts of the engine, that leads me to believe that maybe it is from heat build up over time, low quality oil in the 70's and lots of short trips over the years.

Re: Pictures of 425....
Man if you think any of those pics are dirty you should've seen the 425 in my 78 Brougham. The car had 170, 270, or *70k miles on it and it was so damn funky in there... I used degreasing foam under the valve covers and it took a good 4 or 5 applications before I could even SEE the metal. I almost doubt it ever got an oil change until I bought it (it died anyway.)

Sounds like one of the warning lights, like for the alternator. Can't really say unless you can tell which one it is.
I thought only the EFI cars came with the economy lights. And if that was the case, the light should be on all the time under WOT. Fuel economy sucks under WOT!
I know the generator light is orange, and the oil pressure light is red. But I can't remember the temp light color.
When I opened up the 455 I had years ago, I actually picked large chunks of caked gunk out from under the valley pan. The motor ran good before I went in there. That gunk just sat there on the baffle above the crank.
