Many steps forward, one step back.
Progress has been a bit slow on the wagon since the gas tank and radiator install. I have this:
And this:
To thank for that. But this Sunday, when the sun was out and the temperatures were in the Goldilocks zone for outside car-workin'-on, I managed a few hours of good progress.
Chrysler was known for many great engineering achievements in it's time, however, relatively mundane tasks seemed to escape their competence. I have never, for example, seen a Chrysler engine that did not leak oil from the valve covers. The 383 in this Town and Country was no exception. And when I removed the valve covers to install a set of fancy, high dollar Moroso synthetic rubber gaskets, I found the valvetrain encrusted in thick black gunk. The valve covers and rocker arm assemblies soaked in solvent for a week, and then I blasted them with the pressure washer. Some amazing before/ after shots:
Then I attacked the engine with a shop vac and a toothbrush (an old one, not the one I currently use for dental hygiene) to get as much crud out of it as possible. This interesting apparatus, made from plastic pipe, rubber hose, shop rag, and electrical tape enabled me to reach deep within the engine to suck out loose sludge.
I decided against using solvents in the engine to break up the sludge, not wanting a deposit to become dislodged and find its way into a small oiling passage. Over time, frequent oil changes and long, high speed drives should remove the sludge remaining. I drained out the old oil, which didn't look terribly bad, and the oil pan, from what I could see, wasn't a sludge-encrusted mess.
I did a bunch of other stuff to basically replace rubber parts, clean things, and get the engine back together. I painted the valve covers, and the engine's starting to look rather good, now:

And, hey, it's getting dark, let's fire this thing up! Wait, why won't it start?
After several minutes of cranking, backfiring, and general "WTF"ing on my end, I decided to crack the valve covers open and make sure everything was OK inside. With the coil wire removed, I cranked the engine at the solenoid, and all the valves were doing their happy dances. So...what's the matter? I did finally get the engine to start and run, but it sounded horrible- like it was running on a number of cylinders not equal to 8. Or even 7.
Somewhere back in my head I remembered futzing about with the car one day a few weeks back and accidentally bumping off a couple of spark plug wires. Sure enough, when i checked the cap...#8 and #2 wires were switched.
We all know what happens next, right, Crank, vroom, etc? Which it did. Horray! And then, once the thermostat opened...wait, why is it spraying water everywhere?
Oh.
One of the freeze plugs behind the exhaust manifold on the left side of the engine was spitting out water. Guess what the next project is going to be?
