Engine siezure

Hi there, I have a 1979 austin maxi 1750cc, petrol, manual transmition fwd.
it has done a grand total of 22000 miles, and hadnt been used for aproximatly 7 years till it was bought by my self. The engine cranked over fine and it did run but the following morning I tryed it and it just cranked over, so I left it whilst I did other repairs, later on that day I atempted to crank it over again but the engine had locked solid, even in gear and rolled back and forth would not budge it. So far I have removed the sparkplugs and poured hot diesel down the cylinders but have a hunch that it wont help. The gearbox is in the sump of the engine like the old mini. Any ideas, I realy dont want to have to strip down and rebuild.
Do you
have the same problem?

With the spark plugs out will it turn over? I dont't know how that much about austin, if you can you get to the flywheel pulley, use a breaker bar and socket and see if you can move the engine a little in each direction, remember that is with the spark plugs out. When you had it running did you hear any knocks? After you put diesel fluid the spark plug holes did you try to turn it over then?

With the plugs out all it would do is make a click noise as the starter meshes with the flywheel and then it would be silent. When I looked down the bores with a lamp they looked dry, when it did run a few hours previous it sounded fine, no squeking or nocking noises. The flywheel moves about 2mm either way and locks up. Does the same still with the diesel in the bores which has been there for about 6 hrs or so.
Is it posible that when it turned over but didnt fire that petrol in the cylinders has washed the oil off and now caused a piston ring to dig in to cylinder wall?
Thanks in advance

I don't think that is the problem with the petrol washing off the rings. When you are able to move it a little each was do you hear a tap or bang when it binds up?
