About to buy my first diesel 2007 6.0L Lariat F-250, can anyone tell me if it’s bulletproofed from this picture or will I need more? Also what is the blue box? And how did this engine look overall clean, not clean, worrisome?

Someone mentioned possibly replacement parts due to repairs or front end damage. When you look at the front wheel well the frame to looks like it has an add protrusion. Could this be from a bend and then straightened? I don't personally know. Either way. the odd mix of old vs new parts. I wouldn't even look at this unless you have the VIN and check history.

I was in your boat 2 years ago. I wanted a diesel and was willing to do almost anything to get one. After reading a lot of what to look for - and then going out and looking at used trucks.. holy shit they are just waiting to fuck an unsuspecting buyer. BE AWARE. I finally said fuck it, bit the bullet, waited until finances were right and bought new.
