Oh yeah. My truck sold in Oct 2007. Thats 40 months, 10,000 miles a month, a little over 300 a day. Probably took weekends off. But it's great to hear that about an 08. Good news for all of us.

 

I see no reason that this motor would not see 200-300K for most people...if you are doing the proper maintance

 

And after 300k? what do you suspect?

 

Most people will trade by then...those that are **** about their maintance will go longer.

Then there are the 2nd and 3rd owners who will blow it up.

 

How many people drive a car until it's engine dies?

Not many I've ever known, more often than not the car is driven until something breaks that exceeds the value of the vehicle to properly repair. At that point it's considered not worth repairing. My old 2000 Contour is worth ~$1,500 but only has 95,000 miles on it. If the transmission were to grenade tomorrow I would likely scrap the car because it wouldn't be worth a $2K tranny job. The engine will likely go another 100,000 miles, but I doubt it'll see that.

I suspect most of these trucks, as well as past year trucks are retired long before the engine is ready to give up the ghost. Even once aftermarket parts become readily available a major high pressure fuel system repair is likely to cost $5-6K due to the extensive amount of labor required to change out many of these components. After 15 years and 2-300,000 miles any potential owner would likely look long and hard at whether or not such a repair is worth it.

I believe most engines will never get worn out, but other surrounding components will force their retirement.

 

Crazy001, thats the scariest part of this truck. Im not concerned about throwing a rod on this engine. Im concerned about a $6k fuel pump, $2,500 for thermostats and radiator, etc. They are ridiculously expensive to repair compared to other diesels, and especially compared to gassers. Even if the truck is worth $25k I dont want to invest $6k in to a fuel pump. Thats 25% of the value of the truck in 1 single repair. Then what if you lose an injector the following month?

 

And that right there will be the determining factor in how long these trucks will last.

I'll admit to anyone that as of right now I'm afraid of owning a newer diesel engine outside the warranty period! We'll see how they age over the next few years, I think there's a good chance that they will hold up pretty well. Tim weill tell.

 

Well guys here's the X factor in all that reasoning, in 2014 model year (or it might be 13) these trucks have to go on a diet. The fine federal goverenment strikes again. So, if we want to tow any serious weight we may have to keep these running. Interesting story. I found another 7.3L 2003 with 42,000 miles. Truck had it all, DRW, 4x4, leather and full power. It was pristine. Price $ 26,900. I talked to the guy, a dealer and the best he would do was an even swap for my truck. I passed but I think we may find that as they reduce the might and size of these trucks the 08 thru 13 models will be in demand the way the 7.3s are now. Let's hope.

 

There's seven 6.4's on Cars.com right now with over 200K miles. Prices vary from $13K - $22K. Dozens more over 150K miles. Not sure on drivetrain condition, but pics look pretty clean.
