    ATF in the cylinders, breaker bar, crank bolt, patience, back and forth, MORE PATIENCE

    READ CAREFULLY BEFORE TRYING THIS TECHNIQUE

    alright

    tell us what you did to confirm that the lower end was seized...

    if it is infact seized, then this trick may work for you
    but you NEED PATIENCE with it...

    first check to make sure your timing marks are correct, you want to make sure it didn't jump time and smash the valves, cause that could make the motor not turn over as well...

    if you are confident that its the lower end then take out the spark plugs and fill the cylinders with ATF, yea, thats right, automatic transmission fluid...
    then let it sit for a day, yea a WHOLE DAY

    now you need a big ass breaker bar with a socket the size of the crank bolt...

    the next step is what takes the real patience...
    you slowly need to try and turn the crank, back and forth, back and forth...
    when i started on a seized motor i could barely get it to move like 1 degree, and then i kept working it back and forth and i got to 2 degrees, and then 3, then 4

    it takes a lot of time and patience to get the motor to fully turn over again, but the ATF should do the trick...

    this was done on a saturn that was starved of oil and locked up TIGHT...

    you might have to use a pipe on the breaker bar to get it to start moving
    and you want to turn it until you run into resistance, then go back the other way, you DO NOT WANT TO FORCE IT... it will require force, but you need to know how much is too much

    the key is SLOW AND REPETATIVE, back and forth, and if it doesn't budge after a day then give it another... this has been proven to work so trust me... best of luck

    Make sure nobody left a screwdriver in the ring gear on the flywheel to keep it from spinning :lol: . Sorry just being a smart ass. Best of luck getting that thing unstuck. You might have the best luck just rebuilding the bottom end with some new rings and bearings.

    all motors tend to lock up when they sit for a long time.

    remove the arpk plugs.. dump a little bit of oil down each cyl.

    turn over by hand until it gats easier.

    if it doesn't, you got more serious problems...

    they usually have a start up gaurantee on the engine. my engine sat for 2 years and started on first try/engine rotation.

    If the ATF doesn't work you can also try some Brake Fluid, that shit will take paint off your car so be careful. it should breakdown the carbon and gunk in the rings
    Just substitute the ATF For brake fluid and follow the same procedure as above.

    Good Luck,JIM

    The ATF trick is your best option. A good penetrating lubricant :giggles: would also work very well in this situation. I prefer JB 80. Same deal as the ATF. Spray some in each cylinder, and leave it for a day. Also, pop off the valve cover(since it doesn't take long), check to see if your valves are oily or rusty. With the valve cover off, you'll have no problem looking at the cam gears and checking the valve timing. If the cylinder walls are pitted, I'd sue for your money back after giving them a chance to make it right. If not, then you should be able to break it loose and fire it up.

    One other thing. Make sure one of the cylinders isn't full of fluid. I doubt that would happen, but hydraulic lock wouldn't let that engine move at all.

    if it does have hydro lock, crank the motor over (after you get it freed) with the spark plugs out. the fluid will be ejected from the cylinders. i'm sure it will run like shit for the first few minutes.
