I emptied the old oil out of my cossie sump and got half a mug of water out first, it has been stood a year with some of the breather pipes and block blanking bolts out and wondered if the head gasket had given up, block was cracked or could that much water be from condensation or what?? It fired up on all4 cylinders and hasnt lost water since i refilled the tanks with anti freeze, should I be worried?
