Thanks in advance for any and all help.
I currently own a 99 F350 CCLB 7.3L ZF6. All modifications were performed by me, and can be seen in my signature.
I have found a 2008 F250 Ext Cab LB, 6.4L, Auto, 75k miles, Tow Package with tranny cooler, 4xr4 Manual locking hubs asking price is $24500. All maintenance performed at regular intervals. Transmission flushed and new filter at 55k, coolant flushed at 55k.
I may be considering selling my truck in order to purchase this one. But i know very little about the 6.4L. I had told myself i would never sell mine until i could buy a 6.7L but this truck is in really good condition and very well cared for.
What do i need to look for when purchasing a 6.4L or 2008 Super Duty in general?
What maintenance will need to be performed in the near future?
What modifications are considered necessary mods, and what are considered highly recommended for Daily driving and bassboat towing, and occasionally a track hoe. ?
Any articles or links to read for reference are greatly appreciated. Or if someone would like to summarize something that would be even better.
For example: if someone was purchasing a 99-03 7.3L i would suggest they check for blow by, check for color of smoke on cold start. Check smoke under load and if turbo cleans up smoke. Check turbo shaft for play. Check oil pan for leaks as its difficult to replace. Check rear fenders for cancer as its very common on those years. There are plenty more but you get the point.
For eXample Common Maintenance Items are:
ICP, IPR, EGR Tube, Clutch Pedal Bushing, and several others.
For Recommended Mods: I would suggest they install a 6637, S&B, or Ford AIS intake. 4-5" Exhaust preferably MBRP. A PHP Hydra Chip for Tunes, and IssPro Guage set with Boost, Pyro, and Fuel pressure for manual, or for auto replace the fuel pressure with tranny temp guage. Its also common to install a billet turbo wheel for faster spooling and better boost and to eliminate turbo surge associated with most tunes.
For more in-depth mods: I would suggest either a return spring upgrade to boost fuel pressure, or a regulated return kit, or a 4-line feed kit. An High pressure oil crossover line. A 38R turbo upgrade for late 99-03 or a Van turbo upgrade for early 99 models. Either 160cc/30% over injectors or 178/80 injectors for moderate upgrade reaching around 400HP. For automatic transmissions they can only handle a certain amount of torque before they are very well known for going out. I am not as familiar with autos but i know they need to be built to withstand hardly any engine modification.
Thanks Again
