    When I was younger, my dad had an old fiberglass buggy tub that he was going to build. He found an old beetle for a doaner chassie and the engine was siezed up. For a couple of weeks, every day he had me go out and spray brake free in the cylinders. And then one weekend we tried braking it free by dragging it down the road behind our neighbors truck. My dad is about 6' 4, he was in the beetle and I was in the truck with our neighbor. When we got up to speed my dad popped the clutch and the car jurked so hard it sent him into the windshield, the windshield popped out, the wipers were up, so they acted like springs and slapped the windshield back onto my dads head and sent him back in the car. We laughed so hard we had to stop. And the motor was still siezed.
    That sounds like a funniest video moment right there,,,,

    anyway you'll differently brake the oil ring thats stuck to the cylinder bore

    engine is out.... what a pain in the ass it was to get at the torque converter bolts since the engine wont turn. I pretty much had to pry apart the engine from the trans, pull the engine up on the driver side only to get some space inbetween the two, sneeked in a wrench and got it off

    I've personally seen this one work twice now....

    I can't remember the exact process, but here is the basics of what I've seen my grandpa do before. He would get the engine hot (even if it is just letting sit out in the sun for a few hours) and then continually put small shavings of dry ice into the cylinders. I guess the rapid cooling of the piston actually caused it to shrink and expand, which eventually freed it from the block.

    Oh, I didn't realize the engine was out. Dry ice on the bottom side of the pistons (where they are probably stuck to the block) might help also.

    i think i might just blow up the engine :-)

    this sucker is not going to unlock if i put 10,000 volts through it :-)
    when I went to 'drain the oil' there was none... not a drop...

    Not Coke in an engine, but have heard that if you burn up an auto tranny, a can (not bottle) of coke will get you home if you dump it in the tranny. I was also told that it renders most of the internals unusable for a rebuild.
