Robert,you wrote "offul sounding stink boms you call an engine" Must times when a diesel is running out of time they produce black smoke and stink as you put it. The louder sound is caused by the injection of the diesel fuel. The compression is higher in a diesel than a gas engine. The fuel is injected with high pressures. I for the most part like your choice of word "superior" HaHaHa. You also said "by and large I believe have more torck" yes they do have more toque. In many diesel applications they run at lower RPMs than a gas engine. Over the years I have worked on many gas and diesel engines. Growing up in a family owned small business you work on whatever comes your way. Art ----- Original Message ----- From: "Robert J.
