The dealership told me that my compression was low and that they needed to check the rods and if they are not bent then i have to replace the entire engine.

400Lbs would be good for that vehicle.but all cylinders should read withint 70% of highest cylinder reading. No cylinder shold read below 100 lbs. But on a diesel that would be a really sick puppy if it were that low. Normally rods get bent do to hydraulicing. meaning a liquid getting in the cylinder.
