That carbon ring may be a fire ring designed to keep the compression in the cylinder and away from the head gasket. Pinching head gasket material down on top of a liner that is not some type of metal is not going to prevent compression from leaking into water jacket. Case uses fire rings on their tractors. Gaskets come from Case without the rings and you must buy them seperate. Some after market Case gaskets have the fire rings in them. Make sure you have the right gasket as it sounds as compression is getting in water and the exhaust would make temp run high. Does it seem to be worse when you load it hard and the boost is up?

Don't know what the current appraoch in head gaskets might be. From the service manual illustration (not great) original appears to be a single thickness metal, maybe copper. Doesn't appear to be a fire ring to it. Does appear to have a step to the liner flange. [Reply]  [No Email]
