The crankshaft can be turned by removing the hexagonal plug from the righthand side of the engine there is a 14mm bolt that can be turned with a socket and bar if the engine is not siezed.

As Superjack says this is the way. But first of all i think that if you don't have mechanic experiance it is better to give the sf to a mechanic. But if you still want to try it by yourself,i think that you must have the service manual.
Here some help for the first steps:







Take care,i think something is broken inside and if you try this work perhaps you gonna make more damage.

Where abouts are you, maybe someone close who may be able to help you.

Thanks for help. I removed the left cover. Typical bolt turns 3/4 then jams. Im in heswall on wirral. Thanks

I think a valve maybe stuck. Would crankshaft jam if this happened?

Yes piston would hit it do not force it , If you remove the camcover it could be possible to see if a valve was stuck in the open position, in which case its a head off job.
