Not a great start to the summer vacation......Driving down highway towing trailer....everything going great......EGT's about 800ish.....poof......smoke blowing out exhaust, truck loses power and runs rough. Shut it down fairly quick once we found a safe spot to pull over. Coolant is fine, oil looks good. I see a bit of an oil mess under truck that looks like it had come from up by the turbo. So I'm thinking now that it might be a turbo seal that blew. Get truck into a local dealer and they are telling me the scan showed misfire in cylinders 2 and 7. They will be doing a manual compression test.Should I be assuming the worst? could it just be an injector or two? Rocker arm? Truck is deleted and I do run a tuner in tow mode when hauling the trailer. Road was fairly flat and like I said, EGT's were good.Thoughts from the experienced here?Thanks.

Turbo's very common failure... Injectors also very common. Keep us informed!!! Way to wreck a holiday, eh? We had an f350 that blew head gaskets on a 6.0l on holidays

how many km on the truck? Chances are pistons/cylinders are fine unless you got 400+k. I agree with Ric, turbos common issue. Never had issue with mine when i had one but i did have 3 injectors go bad, pricey as they weren't on the same bank.

Only 240000 and it's a very well looked after truck.

If it happened that sudden and no signs until then I’d guess a turbo.
not sure if dirty diesel in Red Deer is still around but they used to do a lot 6.4 stuff. May even have a takeoff.

Sounds like a turbo, and hopefully thats all. My buddy just blew his turbo on his 6.7l ford. He had to wait, and it was a 6g bill.

You delete your EGR too? I just had similar symptoms on my Duramax and it turned out to be a stuck EGR valve.

Stealership called. They are saying no compression in cylinder 2. Shoot me now.

Oh boy.. I have helped a few family members through 6.0 swaps.. I’d guess you are looking at 15k or better

Buddy lost his first 6.4 motor couple years ago at 165k just out of warranty, burnt up piston #8 I believe he said. New DFC longblock and turbo but they didn't replace injectors which may have been fatal because last week he lost the replacement engine, #7 this time. So he's stuck down in Nevada getting another new longblock turbo injectors fuel pump rails etc everything.

I should add my friend was running a Bullydog on tow setting I think since the truck was new in 2008. The first failure was in Spokane area and he had a DFC approved shop install their basic longblock and I think it was a slightly upgraded BD Turbo. Now 2 years later he's dealing with another DFC dealer in Nevada and going with the upgraded longblock, he's figuring out which turbo to go with today I think. Of course he's trying to get warranty through DFC but because the Spokane shop re-used the original injectors this may be difficult.

There may be some alternative shops as well, Alberta superdutys (facebook) does good work I hear and has lots of used gear. I know a guy who has 3 rebuilt status trucks from him and he seems pretty happy with them.

DFC? Early talk is about $18,000 for a longblock plus 17 hours labour. A lot of cash for a 10 year old truck. It's in great shape and we'll looked after, but worth fixing?? That's a lot money that could be put towards a 6.7 truck. What to do....

Yeah I don't envy your situation ZRrr. If it were mine I'd look into a Cummins swap but I'm not sure how well integrated the kits are regarding electronics.
