Thanks for the advice guys. After a little bit more tinkering and getting a second, third and fourth opinion from qualified diesel mechanics, i came to the same diagnosis as I feared. I probably have a stuck valve. I am able to turn the crank by hand but not a complete revolution. So tomorrow's project will be to remove the valve cover and check if any valves are stuck. Then basically bath the engine with transmission fluid or Lucas oil and let it sit for a week, hoping and praying that I get lucky and everything breaks loose. But if I have to, I am capable of removing the head and I'll have to send it to a machine shop to get worked on. Again hoping and praying that it doesn't have to come to that. To answer your question garrison, I have not thought of getting an outboard motor. Simply because it's just not in the budget. I did however think about putting her back in the water anyway, with or without the engine running. It is a sailboat after all. All the rigging and sails are in great condition. All electrical systems work. I've actually just worked out a mooring buoy that I can use. If I can get the bottom painted and finish re bedding the rest of the windows, make sure they don't leek anymore, I don't see why I couldn't get her back in the water. I can still work on the engine while she's in mooring. I have some time. Actually I have plenty of time. Yesterday was just one of the hiccups that I'm sure I'm going to encounter. It just happens to be the first problem. But I'm "sailing on" with my project and will keep you guys posted.
