I feel that engine is going to have to come apart regardless.
If you plan to use the motor / rebuild it then you need to unstick the motor . Its far easier to disassemble an unstuck motor .

True, but with the crank our you can beat on the pistons individually, top and bottom.

If there is a rush to get it apart , thats one thing , if there is no rush , thats another thing . I did ask if there was a rush .

In reply to # 1496665 by Lizzard Are you in a rush to get it "free" ?
If you have time , put the drive shaft back on , park it on a slope and let gravity pull on the lock up .

Hi,
All this is assuming that the pistons are stuck in the bores. That isn't the only thing that can lock an engine. I just dealt with an engine which had spun a bearing. With both shells on the same side of the crank journal and lots of debris spread around, the rods and mains both had to be undone before the crank could be turned.
All the best,
Paul

Well, I know I'm going to get yelled at, but here it goes.

I've brought back a stuck MK1 GT6 engine by soaking the cylinders with diesel fuel for a few days and breaking it free with a big monkey wrench on the crank pulley. Once it was free to do a full revolution I didn't do anything more until I was ready to crank some oil onto the bearings. I have no doubt there "must" have been some physical damage to the cylinder walls and/or bearing surfaces, but I put the car into service anyway. I figured: "I'll pull the engine when I get symptoms, why pull it now, just because?"

As it turns out, I got over ten thousand of miles out of that engine after bringing it back to life twice from being stuck. It never failed - I just replaced it with a MK2 many years later.

Big monkey wrench. Break it free. Get it running. Check the oil pressure. Check the compression (after a while). If all's OK - just drive it.

OK guys, ... don't yell at me "too" much. drinking smiley

You have to admit parking it on a hill in gear to break it loose invokes this....

So recently in springfield, ma. An all electric city bus refused to move. The driver radioed in, it was suggested by the shop to unplug the battery. Of course they forgot to mention he should choke the wheels. Didn't turn out to good. Once the battery was unplugged, the brakes let loose.
