7.3L with 300,000 mile

[rcoooper311]

I am considering buying a truck with 300,000 highway miles on it. So far everything I have read states 350,000 miles is about the normal break in for the 7.3's before any minor or major engine work is needed!

Can anyone tell me what I might expect to or need to consider having replaced soon if I buy this truck. I have heard injectors are a must every so often but I don't the replacement interval for them or the other parts.

Is there anything I need to look at when I go to inspect this truck?

Thanks!

I have 416,000 on mine. Just replaced the transmission for the first time at 407k. Motor still stock and never touched, have replaced o ring where oil leaks have shown up from time to time, mostly in the last 50k miles. I had to replace o rings on the HPOP, turbo pedestal, turbo mounts, turbo EBPV, oil cooler, and HPOP lines. Several unihubs and alternators. Just replaced the radiator last week, had a crack in it. Power steering pump, hydro boost. I think that's about it? Injectors still the ones that came in the truck, I mention that as you did. We have three of these 7.3 in our family, mine and my brothers both have over 400k miles and my dads retired to the farm and has 350k? All have the sme injectors that came in them. None of them smoke any different than the day thy were new. If the truck has been taken care of and not abused, preferably stock, it should be fine.

Yeah I'm in a similar position, going to look at a '96 7.3 with 241k. What's important to keep my eye out for while inspecting the truck to make sure it's been taken care of. I'm 19 and just getting into diesels so some help would be appreciated

Mason, Just have a flashlight handy to really look at the engine, belts oil leaks and leaks of any kind. Carfax if available or maintenance records. Not sure where you live but block heater for winter time is a must with the 7.3 good working glow plugs are a must. Check for corroisson inside the coverings of the batt cables. Create your own post in here and address your questions and concerns about that 96.
Good Luck!
