My father in law has a 08 powersrtoke with 280,000 miles on it, about a week ago it started making a horrible knocking sound. He called me and i could hear it over the phone. He shut it off and let it sit a few hours went out and started it and there was zero noise it ran perfect. Then yesterday on his way to work it started making the same noise only much louder, he was only about a block away from work so he limped it there. His friend owns a diesel repair shop so he had it towed there and his friend said one of the pistons and the block is shot do to a bad injector. They are quoting him $15,000 for a new motor installed. Is this a common problem with the 6.4?

 

i think more information is needed. What codes were there, how did they diagnosis this as the issue and how did they determine that they entire motor needs replaced.

 

Sad to say, but this happens more than it should on common rail engines. 5.9 Cummins and 6.4 PSDs being the worst about it.

 

I'm guessing sloppy injector washed some bearings out? Be curious if it has been regening for 280K miles or was deleted at some point. I'd say he got his money out if it at around 60K miles a year.

 

He said there was a warning that said something like shut off vehicle as soon as possible, as far as codes go i dont have the info on that. Nothing has been deleted on the truck as far a emission stuff goes. Its 100% stock. The only problem he has had before this was a leaking radiator when it was new. He uses the truck too, pulling over 12,000 all over the western states

 

280,000 with the DPF on, and no repairs but a radiator. I'd say that's pretty good. I'm sure he's not happy about it as an older generation diesel engine should go double that until a major overhaul, but unless or until the technology improves or the EPA gets closed down that's probably as good as it's gonna be. There are some 6.4 engines showing up on craigs list around the country or in the junk yards if he wanted to try that route. Hope it works out for you.

 

Yeah he is pretty dissapointed, but like you said he is used to the older diesels. He has 5 7.3s that he uses for his business one with over 450,000 on the original motor. He has a lead on a used engine with 40,000 miles, the guy wants 8k for it though. He is also looking at buying a 2013, I have read that there have been a few problems with those though.

 

The new technology is I guess a little better. What distressed my about my 6.4 was the oil dilution. It is a very different truck with the DPF off. If he has all those 7.3s he just needs another. They can still be found with under 100,000 miles. Even with a 100,000 mile head start they probably out live the 6.4 or the 6.7 and operate a lot cheaper. I sure miss mine.

 

Thanks for the post..It's not often we see a post about a stock truck and 280k on the motor....this gives me hope that these motors can last more than 150k..but far from the 500k minimum miles everyone expects from a diesel motor.

 

I wonder if anyone's tackled putting a 7.3 in an 08+ chassis.

 

In fact there is a 7.3 extended cab DRW with a six speed manual on ebay right now with 30,000 miles. It's in new jersey so I'd want to know that it wasn't under water during the storm but that will make somebody a good truck if it wasn't flooded.

 

Actually putting a Cummins from Destroked in an later model Super Duty is more popular.

The problem with the 7.3 is its not emissions compliant in any of the newer trucks.

 

A dt360, MD manual trans would be my goal lol

Hard to make the electronics work.

 

I know this is pretty old, but I thought some of you would be interested to know that It turned out being a broken rocker arm. Thats it! It did make a horrble racket though. They ended up changing the whole rocker assembly on that side. The final bill was just under $1,000. A heck of alot better than 12-15 thousand. He also has just over 300,000 on it now. Still running completly stock.

 

Thanks for the update. Far cry from a trashed block like originally though.
