After owning my first car (g REG 90) for a few days i noticed it was constantly reading overheating, after reading up on it and completley flushing the coolant system + changing the thermostat to no avail, we decided it was the temp sender... took it into a local landy mechanic just to be doubly sure, where he discovered that the crank pulley could be rotated slightly by hand. He said the crankshaft was worn down and that i needed to replace the engine (and kindly offered to do it for £1000... yeh, right !) he said the woodruff key had worn right down aswell, is this repairable, or do i need to invest in a new engine?
