Depends on why it is seized?
Really need to open her up and see what damage is in there.
Or you could "unseize" it and it not last another 5 mins.

If it's seized then it's overheated - probably seized on the pistons which would probably mean the piston rings are seized in a compressed position so even if you got it free you wouldn't have much compression - if it were the bottom end seized then you'd need new shells and a regrind anyway
Try a diesel soak - if it works you got a running car - if not you'll be stripping or replacing the engine anyway

Yes it can be siezed due to being left, and your mate is right, putting a drop of diesel down the bores will help to unsieze it if thats the problem, i personally wouldnt use brake fluid.
I have also come across engines that were siezed because an ancillary component was siezed, IE a citroen Berlingo that had locked up because the altenator had seized,
If its the bottom end thats seized, then a strip down is the only solution

one of my uncles bought an old tractor few years ago with a seized engine, he poured n poured diesel down the injectors, until he took the head off n found no end of dirt n twigs n other stuff like that 
worth a shot.

Hi,
How about a huge hyperdermic syringe ... and I mean huge.
Close valves on No.1 cylinder. Remove injector or heater plug. Fill cylinder with oil. Screw hyperdemic into the aforementioned "plug" hole. Prime the syringe. Belt plunger with a club hammer. 
Principles of Hydraulics will multiply the pressure of the impact .... ask that Greek philosopher bloke. Fluid will magnify the impact ... ask Barnes Wallis (of Dam Buster fame).
There, I've invented it. You make it, and send me half the profits.
Or maybe a grease gun would do the same job ..... but use a lot of grease.

I have something of that ilk to 'rejuvenate' grease nipples - you'd need something you can hit with a 4lbs sledgie to make any difference! I'd run with pouring diesel, engine oil or similar down the bore (NOT brake fluid, WD40, petrol etc) and leaving for a few days somewhere warm (heated garage, south of France ...) then hand cranking over slowly.
This worked perfectly for my veteran engine - each winter I pour a smidgen of 3in1 in each bore and crank slowly once or twice to lubricate the bore as an antidote to petrol drying it out.

Hi,
Not so common these days, but if you have the old fashioned INERTIA starter motor, it is worth taking the cap of the outer end of the armature shaft, and try to turn the square peg underneath with a 1/4BSF x 3/16WHIT open ended spanner.
Alternatively, put the gearbox into TOP, release the hand brake, and rock the car back and fore, with greatest effort on the "back". The idea is to rotate the engine backwards.
I don't know why, but a jambed starter can give a very good impression of a siezed engine. This does not apply to PRE-ENGAGE starters.

grease or oil is too thick, diesel is the way. Me old man collects stationary engines and sometimes buys ones that have seized due to eater ingress, a good few days with some derv soaking in and they free off a treat. He did unseize a big Ruston Hornsby 3cyl diesel that many said would 'never run again' using this method and it now runs sweet as a nut

Yep give it a couple of soakings with diesel (spread it was much as you can around the bores, a cheap squirty oil can with a relatively flexible neck should do the trick; make sure you' don't over do it: ie half a cyclinder full of liquid will blow it to pieces if it does unseize), and then have a google on how to unsieze an engine - I forget the exact process but you have to push it, hit the the starter, and jump hard on the brakes at some point for a few rounds. If it's not too badly seized this will work easily.

Don't try and tow a vehicle with a Seized engine in an effort to unseize it.
You may bend con rods!

Soak it in deasel then turn the crank pully around with a big bar if it still doesnt turn soak it abit more and keep trying till it swings around a complete cycle take out as much compression as you can as well befor turning it over
