I asked the service manager what was wrong with old engine and he said that ford sent them a memo that said "if the engine in these trucks have a knocking sound, do not tear them down just send back to ford and replace with new engine because they are having a lot of problems with them." I assume they are talking about the early chassis cab's. The service manager assumed that the new long block and heads had some kind of upgrade but said that ford didn't tell him. Does anyone know if ford has tried to fix this problem with the early chassis cab 6.7's?
