My John Deere 510 diesel blew antifreeze outside and also inside into the oil pan from overheating.I left it sit for nearly a year,drained the antifreeze and oil yesterday and removed the head today.There was only approximately a litre and a half of antifreeze to drain.The gasket was intack when I seperated it from the engine and head.I have a new head gasket ready to set in place.The minimal damage to the old gasket concerns me.Antifreeze was blown out the opposite side of the engine from the exhaust the day it overheated practically in the centre of the gasket area.
Also, the 1st cylinder of the 3 cylinder diesel engine seems corroded around the top the pistion within 2 inches of the top,and the engine will not turn over at least without further cleaup and lubrication.I oiled all the surfaces when I finished the tear down until I can determine the best course of acton from here.Is this corrosion from the antifreeze or do I have something else happening here.If not, can I clean up the head,cylinder top and engine gasket surface,apply a new head gasket providing the head is straight.It looks good with the naked eye but I plan to check it with a straight edge.Bolt it all back together and start the engine? I would appreciate any help,i am not a mechanic. Thanks Ron
