The names Richard, but everyone has always called me Dukes. I'm new to the thread and to owning a diesel. Recently bought a 94 F350 4x4 7.3 IDI. Not the best with diesels but can help some. I'm a mechanic in the oilfield have worked on anything from the small onan 4cyl engines up to the QSK50 V16 Cummins. Also worked for GM as a diesel mechanic on the first gen duramax engines. Also have an 85 K5 blazer 12in lift with 44 boggers that I compete in mud competitions so can also help with some of those 4x4 questions.
