Thanks for clarifying guys, you can probably tell I've never owned (or worked on) a diesel....
To the OP, if the rest of the truck is in good shape, it's a good investment at only 100k miles considering what you would shell out for a new truck. I went for almost $2k in parts for new stainless brake/fuel lines, new shocks, new muffler, injector cleaning and a few other misc items....and a month of nights/weekends in the garage. I'm at 143K and plan on keeping it for a while.
For all you guys fighting the brand wars, any gasket can fail and/or leak...
As a general comment, exotic cars packed with engineering and technology that push what's possible to the limit always came standard with frighteningly high repair costs, but folks figured if you could afford to buy the car, you could afford to get it fixed. Seems like some of that is trickling down into our everyday trucks. After reading stories about $10,000 HPFP failures, $3000 injector jobs and $5000 head gasket repairs it scares me to think about buying a new diesel.
