G'day Tom, The term blew it, down here means very secondhand! The part in the manifold was a molten mess imbedded in the top of the piston, there was something looking like threads for a bolt, was found by cummins when they pulled the engine down, I have seen it, not pretty! No info. from these companies, but engine is running, not happy. Paid a lot of money for a secondhand engine! I have been rather unhappy this harvest with agco and cummins, but dealer has bent over backwards to help, supplied another machine so we could go on.
