Well, we lost my Dad in 1995 (he was 56 and juuuussst starting to enjoy a couple of the good things in life) so, it made this project even more important to our family. My son, who is 13 now, wants to learn to drive using Ol' green and I told him someday he and I would read a book on how to paint and we'd try to paint it. (read disaster!). That piston in #5 was stuck so tight that we couldn't break it loose by towing the truck and popping the clutch in gear. We tried that a couple of days in a row and EVEN with the head completely removed! She was stuck BAD. I think we soaked all the cylinders for a month with brake fluid but then when we pulled the head, we saw that the rust ring that had built up on top of the #5 piston wasn't letting anything seep past. So I took a very thin bladed knife (one of my mom's paring knives *don't tell her*) and carved all the rust off the piston top and poked the knife blade in thru the rust until I hit the top ring. THEN we poured the knock'er loose in on that cylinder and it soaked a day & nite before it started weeping thru past the rings. Another night of soaking and we started smacking that almost perfect fit pine post on top of the piston with a 2 lb mallet. After maybe 20 try's throughout the day of smacking and re-adding knock'er loose, I noticed that when my brother smacked it, I could JUST BARELY see the fan belt jump. DONE! We dropped the piston in the cylinder as low as it would go, (down stroke) honed that cylinder and prayed for the best. We got lucky I think! Rings seem fine and she's purring like a stovebolt six ought to!
