Hi all, I am about to refresh the engine in my truck. I have a 1993 GMC 6.5 TD Dually w/ auto. The truck has 220,000 and the timing chain is stretched from here to Montana. I have the cooling upgrade, new marine injection pump, hi pop injectors and an inter-cooler, new BD exhaust and a BD jake-brake. I have also purchased Hughes performance transmission setup for diesel applications.
Should I replace the oil pump and have a look at the heads? Is there any thing else I should replace upgrade?
