Last month I unstuck a GMC 248 straight six that was froze solid. It's been sitting outside this guys back yard in Auburn, CA for 18+ years. The only protection it had was a one gallon bucket sitting over the carburetor. I soaked each cylinder with tranny fluid for about a week and got it to budge and kept working back and forth 'til it would rotate freely. I could feel the compression on the spark plug holes and knew it would run. After replacing the fuel pump, starter, distributor, carburetor, I dropped the pan and scraped out the sludge, gave it some fresh oil. Added a radiator, coil, battery and played with it for a few more days and got it to run! I can't tell you how exciting that is waking up a motor like that. Here it is running CLICK. Needs a little more tweeking. I'm just gonna run it and use it for what it's worth.
