Looking at a 2008 F250 6.4l
I am looking at a 2008 F250 King Ranch with 90k miles that is stock and will get a 3 year bumper to bumper Ford warranty. I know these engines had issues with front covers, valvetrain, and making oil ...

The 6.4 was a huge step above the 6.0 in terms of reliability and issues. The biggest issue with the 6.4 is poor fuel mileage stock. If it were me, and you live an area without emissions testing, I'd save the money on the warranty for a delete package. You'll get better fuel mileage than current diesels and really it's a reliable engine and tranny combo deleted. As long as you are reasonable with your tune, get a custom SCT programmer and tune.
If you keep it stock you'll get in the 14-15 mpg area unloaded. You could get a newer gas engine for the same price and similar mileage.
It's a hard decision. The 6.4 is a way better engine than people give it credit for once you delete everything. But resale isn't the best when you sell it.
Negative ghost rider!
The 6.4 was par with the 6.tow at best.
More emissions which gave them fits, terrible fuel economy, more costly to work on, still must remove the cab for major repairs, fuel pump issues, etc. Hardly an improvement. Probably why the 6.4 was only in production for barely 3 yrs vs the 6.tows just over 5.
