I've got an 04 lb7 zf6 crew cab short bed 4x4, was dragging a cummins down the interstate when I melted my turbo, pulled over and she ran off on me, replaced turbo, thought I had gotten the inter cooler clean enough, fired it up she idled good and ran off on me again, this time she was at about 6k for 30 seconds, when she finally died, tried a restart and is blowing compression from one or more cylinders through the intake tube, haven't torn her down yet, haven't heard if these are interference motors or not yet...other than maybe a couple bent valves or dropped valve seats....I'm thinking minor head work....your thoughts?
