03 6.0 for a 08 6.4? good idea?

[arriero4x4]

Hi guys,
I´m planning to sell my 03 6.0 f350 and buy a 08 6.4 f350. I have already had the common 6.0 problems: injectors, EGR and Oil coolers. I have read that the 6.4 has a horrendous MPG. My 6.0 gives me 14mpg hwy. i´ve read that the 6.4 does 8mpg??? that too low! is this true? what about engine trouble? I need a reliable truck.

thanks a lot

I get 16 city and 20(22 if I drive below 75, but that never happens) highway with the mods in my sig. Only problem my truck has had is radiator issues, truck has 111k miles now.

If youve already had those issues and repaired them, keep your 6.0. Search the forums...lots of guys are having major issues with their 6.4s once they actually get some miles on them. Do some research before you make a choice youll regret. Sorry to be blunt, but just my opinon.

If you are a spy (007) and are in need of a smoke screen at the mere tap of the gas (smoke) pedal, I would definitely get the 6.4. Ford calls it "Normal Operation."

i get 15 mpg highway bone stock, never an issue with my 08 f250. You will always here the issues on forums rather than guys just coming on here saying their truck is perfectly fine and how good it runs. Do a lot of research and find a well maintained 6.4, than maintain it well yourself, replace the fuel filters every 5k miles, delete the dpf, and get a tuner asap and you'll be golden with 20+ mpg. Might take better odds and get an 09' or 10' that rarely have issues compared to job 1 2008's.

Agreed with the poster above...trust me I know, as I own a 03 6.0 and people talk about how unreliable it is. I'm just saying do your research and make an educated decision before you do something you regret. If you already have fixed those issues, you're not far from having a bulletproof motor.

What would be the next thing to expect on my 6.0? head gasket and struts? turbo? injectors again?
I have read a lot about the 6.4 having lots of trouble. why ford just used it 2 years? because of the trouble they showed?

thanks

it was for 3 years, and they got away from international so they had to build a new motor. the ford/international contract was up in 2010. also the 6.0 was only made for 5 years. It's not the 6,4 that is the issue, it's the federal gov. making the diesel partical filter mandatory and ford's stupid "regen" process.

So, I think I´ll have to wait until I can afford a superduty 2011.... with a Ford engine... maybe in 20 years from now... I think I´ll keep my 6.0.

I've said it before and I'll say it again...alot of the 6.0 Problems people have are SELF INFLICTED. People push and push that motor, not keeping their eyes on the EGT's or doing proper maintenance and that's when they run into issues. IMO unless you're running your truck hard and keepin the EGTs in the 12-1400* range for longer than maybe a minute or so, you're gonna greatly increase your chances of blowin the gaskets. Whenever I see my EGTs gettin close to 1200* i start thinking about getting off the throttle and backin off. You should've done all 8 injectors at once...if one goes, the others arent far behind is the general rule of thumb. Keep up with your maintenance and have some common sense, and you'll be fine. Keep an eye on your transmission maintenance too.
