Yeah Dan, the up to 02 the engines were AMAZING, then in 03 they came out with the 6.0L and they made HUGE power, but were nowhere near as good an engine. My 03 went through the VGT turbos like a fort fiend goes through refills in their brown mugs! But the 03-07 did have just about the best fuel economy of all of them. I wouldn't wish my 08 on my worst enemy or Larry... LOL it is just a diesel guzzling boat anchor if you ask me.
Starting in 2011 models, international is no longer making the engines for ford and ford themselves have totally redesigned the motor. According to their propoganda, it is supposed to be a beast, but I did see that it has a version of the VGT turbo, (Variable Geometry Turbo) and international had nothing but problems with them. I actually like the compound turbo on my new truck, nice low end boost and HUGE hi end boost, I hit almost 36 lbs when really pulling. But no matter what, the EPA and the Govt, and the idiots at Ford who designed the and implemented the DPF filter can shove that stupid thing where the sun don't shine.
My lease is up in a couple months, and I have got to BUY my next one, I can't turn this one in, I am about 20,000 miles over my lease, so at .25 cents a mile, I would get crushed, so I am looking right now!
Anyone want a 2008 f-350 crewcab dually with a 6.4l boat anchor, err I mean deisel engine??? Sell it to you for what I owe!! Only 6k over NADA, (thanks economy, and fuel prices for killing my resale)
