Hoot, valve cover and air intake plenum with heater element need to be removed. Total time is 1-2 hrs. Also cost wise two less injectors on cummins and you eliminate having to pay someone. If all systems suffer injector failure, do to the high pressure systems around 100,000 miles this set-up is still alittle more reasonable. I love my chevy 3500 but if there isn't some type of improvement in new injectors or an easier way to replace them, then in 3 years when it hits the magic mileage number its gone.I don't mind putting money into it to keep it running. But 5-6000 is a little rediculous and kind of defeats the purpose of buying a diesel in the first place. Hell big block crate motors are 5-6000 grand and will run past 100,000 towing.
