Got 278k out of my old Blazer. Injector pump first replaced at 90k. At 200k replaced the pump again, new head gaskets, (just in case, it didn't need a pump or new gaskets) and a Banks turbo. Started using a lot of oil in 2005, and its been parked in the shed at my parents place since early last year. Ran great when I parked it, aside from using a quart of oil every 700 miles or so.
