Well it depends what the truck was used for if the truck was not driven much the turbo veins could be coked up or rusty causing the turbo to stick, but on an 07 its not all too likely to be an issue. 07's were the best year yes, but that doesnt say a thing to a 6.0, theyre all potential victims if not properly maintained, or treated right.
Huge problems with any 6.0 are the egr and oil coolers alongside the headgasket issues. Its more a chain of events rather than just the crappy TTY headbolts. To start things off is the crappy gold coolant Ford uses in these trucks. It contains silicates, these silicates are very harmful when the engines oil cooler is a finned heat exchanger that is cooled by using the engines coolant. When coolant with silicates in it is trying to pass through that finned heat exchanger it acts as a filter and clogs the oil cooler.
The coolant should be passing through the oil cooler to cool the oil temps then dowstream moving to the egr cooler to cool the exhuast gases. When this coolant cant make it through the oil cooler because the silicates in the coolant clogged it... it cant get to the egr cooler so it spirals into blowing the egr cooler. This causes intense pressures and allows these pressures into the cooling system therefore blowing headgaskets.
Tuning, the factory tuning on these trucks flat out sucks, they have power and torque but they all bring high cylinder pressures. NOT good. Most people run custom tuned SCT's becauxse they get you more power reliably and safer.
My suggestion to you is buy it, these trucks are TANKS, you just have to take care of them. If you buy this said truck take extra money out on the loan and do some prevention modifications such as... oem oil cooler rebuild, egr delete, ELC coolant flush, coolant filter, custom tuned SCT and an exhaust to drop exhaust temps, keep your headgaskets intact for the time being and free up cylinder pressures. Remember drive the bastard hard, they love it, when you baby it is when things go down hill.
