The first question is: does the new engine make more power than the old one did when it operated correctly? If yes, that may be the answer in a nutshell. It takes burnt fuel to make heat. It takes good injection timing, and expansion control, to turn it into work. Residual heat in the stack is waste. Exhaust valve timing, and back pressure can both affact the amount of heat in the stack. If the tractor is making more power than before, and no other changes have been made I would do the cooling system analysis first. Particularly the heat gun analysis of the radiator. Thermal analysis can also show restrictions in hoses, but not as easily. Thermostats that fail to open fully, and internally collapsed hoses are also possible. If these are sound and checked off, I would just swap the exhaust. It is not a 5 minute change, but running close to the edge is not in the best interests of a long engine life. Jim
