I had a frozen motor with the cam stuck in place by the immovable crank/stuck pistons. The cam was in the wrong position to free it. Without the cam free, I couldn't pry up the cylinders or release the head. (Yes, I tried all the fluid heat tricks to get things free.) It was time to get serious. I ended up cutting the cam chain. I suppose this means I will now have to split the case to get a new chain around the crank shaft sprocket. I really would rather avoid that. Is there a split chain with a master link available that can be fished around the crank sprocket or am I SOL? Some other solution? Where is a good source?
