What To Do When Your 6.7 Power Stroke Fails

[@powerstrokemaintenance]

Rebuild or buy new, which are you doing?

[@MikeFullyFulford]

Depends on the condition of the rest of the truck as well. But generally i always lean towards a rebuild.

[@powerstrokemaintenance]

That’s true. If the truck is a rot box perhaps not worth keeping

[@billbabbs3871]

This is a no brainer, it's always easier to maintain your truck and keep it running for as long as possible, if you're plan on keeping it, replacing the engine or transmission will be cheaper than buying a new truck. Me I own my 2019 F350 out right and I'm also retired so buying a new truck isn't an option, plus too all of the aftermarket goodies that's been added on over the years, so yes I'm keeping my truck..

[@powerstrokemaintenance]

A truck owned outright is the best kind of truck 💯

[@raykranzusch4614]

I’m with ya, I have a 2019 F250 KR, told everyone it’s my last truck, if and when the engine goes out I will send it to Dave’s . Hopefully that will be way down the road as long as I do all the services every 5K, fuel every other service.

[@jamesvaldez4093]

I agree with taking it Dave's. Bad dude there on engines.

Rebuild. 100%. For me, I have tens of thousands into add-ons including an air suspension all corners, dual remote reservoir shocks all corners, 4 link rear (Kelderman, LOVE IT). Luckily mine was a 2019 F450 has 70k on it and still worth more than I paid for it since I (again, very luckily) was ahead of the massive price hikes. edit: 68 gallon S&B fuel tank too in stock location. SO GOOD. DCR fuel pump. Mishimoto trans cooler (really an aux cooler I'll never understand why Ford uses the trans as an engine heat sync), ...

[@powerstrokemaintenance]

Sounds like you have a dialed setup! What do you mean ford uses the trans as a heat sync? As in trans helps cool the engine?

[@marksr1907]

@@powerstrokemaintenance 100% The engine coolant flows thru the transmission "cooler" which - of course - spikes the transmission temperature. After extended long runs at load the transmission and engine temperatures are sync'd and often the transmission is hotter than the engine because it cools more slowly (factory setup). I'm really curious why Ford does that - it makes no sense - unless Ford decided they needed to piggyback engine cooling on the transmission. The transmission would probably run cooler air cooled (Mishimoto) without the radiator coolant heat sync. Right now per install instructions the Mishimoto is in line with the factory cooler (radiator coolant) and it's keeping my transmission 10 degrees cooler than the engine on average, and both 15 degrees cooler on average than they were pre-Mishimoto. Hence I call it a secondary cooler. I'm really tempted to remove the factory transmission radiator coolant heat sync. However, keeping it in-line with the Mishimoto keeps the engine cooler too so I'll leave it for now. Perhaps in the future when I swap in a larger Mishimoto radiator for the engine I'll eliminate the factory heat sync completely.

[@powerstrokemaintenance]

Interesting. Thanks for explaining that!

If you fix all the weak points of the fuel system, you've solved most of the problems the 6.7 typically suffers from. Make sure you don't do the things that kill the EGR system of the DEF system. Change your oil and keep your fuel filters clean, you should be good. I've got a '24 F550, and I've replaced that CP$ pump with a DCR, Relocated the upper fuel filter (which is the cause of many of the reported fires) to down underneath, replaced the rear fuel/water filter with a better system and as quick as I can get a cold intake pipe replacment for a '24 F550, I will replace that. Truck now has 7900 miles on it. With the F550 engine detuned, it should be good for at least 200-300,000 miles. I use Archoil in each fuel fillup as well.

[@powerstrokemaintenance]

It sounds like you’re really on top of your maintenance! Best of luck with the new rig!

[@paul91103]

New engine or rebuild would be my balancing decision. Cost, downtime, availability of both would all factor in. And keeping the truck that has been upgraded is an excellent point. Who wants to rebuy and install all those goodies a second time. Hopefully the disciplined MX will keep the rig going in the hundreds of thousands of miles. Great topic to explore.

[@powerstrokemaintenance]

Indeed! It seems like it’s better to just fix the motor rather than parting with all the custom parts! I suppose if your truck is rusted out then perhaps that could be an argument in favor of buying new, but still. I would strip off all my upgrades 😂

[@AlbeeSoaring]

I ran into this with my old tundra I had. I was planning on rebuilding the engine when it blew, however the block was rebuildable so I had to go with a crate motor. That turned into a nightmare cause the shop I had do it really should have told me they couldnt handle the job. With my current truck 2016 F350 diesel, I would definitely rebuild or replace the engine if it was to fail, unless the truck is ailing from lots of other costly issues then Id replace the truck.

[@powerstrokemaintenance]

That sounds like a tough experience. Who did you end up getting to do the Tundra rebuild?

[@GilStephens-si9ec]

2006 Chevy Silverado 5.3 4x4 driving to the wheels fall off couldn't see paying 80,000 for any truck

[@seanc6514]

You might get a couple bells for 80k today but definitely no whistles. Decently optioned diesels are over 100k right now.

[@powerstrokemaintenance]

It’s absolutely absurd. For how many issues they have, diesels these days shouldn’t cost that much haha driving yours until the wheels fall off is the way to go

[@willb7975]

Agree with rebuild/repair attempt by myself - considering mods/customization setup of my '17 F350.

[@powerstrokemaintenance]

It seems like a good option!

[@PatrickHennelly-uc3mz]

I would agree with probably just getting a new engine. However, I would also look into buying an older truck as long as no big rust issues on frame and underbody. Prob go with a used 7.3 and no emissions crap

[@powerstrokemaintenance]

Makes sense! Emissions does seem to be the biggest issue across all of these trucks. It’s a damn shame

[@jimm2442]

I think the CP4.2 will fail within 100k but the engine likely won't as long as you maintain it properly. I am a retired mechanic so I lean towards rebuilding but I am 70 so I don't know if I'm up to it. That said I don't care for Ford, I have seen too much. My choice is the L5P Duramax.

[@powerstrokemaintenance]

Nice!

[@pat9125]

I agree with rebuild. I am curious about the "oem junk" comment though.

[@powerstrokemaintenance]

I’ve found basically all the stock suspension and steering components from ford are junk. They fail under hard use after 50k it’s insane

[@pat9125]

@@powerstrokemaintenance Interesting. I wonder if it's the same for 24s. They changed the suspension a little and have no idea if anything was upgraded. Will be watching it for sure.

[@genehart261]

Is 2000 a modern vehicle? I still have my Dodge Cummins and have no plans to get rid of it. I do get offers. I really don't see that it will ever need a rebuild.

[@powerstrokemaintenance]

I consider modern anything built in the last 10 years but that’s just my opinion haha that sounds like a mint rig! Did you buy it new?
