so there it is, the whole reason why my engine seized, and my crank wouldnt budge...
EVENTUALLY got the sump off.... and then saw some little pieces of metal in it...
the shell had actually stuck to the crank shaft...... then when we took it off, we saw that the crank will need regrinding - slight scuff marks (its was on number 2)
So......... LUCKY LUCKY ME!!!
