The 642 is a complicated engine but a good engine. Problem area is oil cooler seal leaks. If it’s been done you should be good. Timing chain stretch can be an issue also usually related to the gasoline rated oil they spec for it in order to protect the DPF. I prefer to use a real diesel rated synthetic such as Rotella t6 or similar. This will protect the engine but a small possibility of plugging up the DPF. If it does they can be removed and cleaned out, or removed and tuned out. Also, I would look for a 07 or 08. 09 and later would have DEF and more issues to deal with.
