[Healeys] Frozen in Place Engine - 1961 BT7

Ibm going to read between the lines. Assuming that the engine was rotated or ran before the several years of sitting and no mechanical issues known, again assuming from past knowledge, the usual culprit is a bit of moisture in bores that had an open valve while stored. The corrosion is usually between the top of piston and the first ring.  It doesnbt take much corrosion to lock up a piston and it doesnbt take much to break it loose. Forget the crank nut. Put the car in gear and rock it back and forth with the plugs out.  If it doesnbt break loose then something else is amiss and probably was when it was parked.
