I have never heard of this happening before but my friend has a IH Scout with a 345 ci engine and the camshaft broke. The mechanic has it all apart and can't get the broken off back part of the camshaft out of the block. The mechanic is about to give up and my friend wants me to take a stab at getting it out and putting it all back together. Has anyone ever encountered this and have some kind of trick to getting it out of the block? Is anyone interested in buying it after I get it back together?
