This article describes exhaust issues we encountered on our early NT37. It is a postscript to Cameron Sharpe and Jim West’s 2008 SENTOA article on high-temp exhaust issues they corrected on their early NT32’s. 

If you recognize the white Cummins wet-exhaust elbow in this picture (it’s bolted directly to the turbocharger at the back of the engine) and you’ve never had your wet-exhaust elbow off to inspect it, this article is for you.
