here is one more for your viewing pleasure. Comes from YouTube, PowerStroke help guy. He finally gets his hand on a 6.7L Scorpion engine.

Some insightful comments made during the video. He also covers the main bearings, and their lack of keying to hold them in place, as mentioned by a previous poster.

Good god this video is an eye opener. The 6.7L is a definite improvement over the 6.0L and 6.4L but still a lot of inherent design issues. I think my jaw dropped when he stated that Ford fixed the front cover design by making it leak coolant externally rather than internally when cavitation wears through the cover. How about fixing the cavitation problem to begin with? This type of thing is exactly why I did not buy another Ford; buy a truck with inherent design issues. Maybe they will rear their ugly head while the truck is on warranty and you can go and fight with Ford about getting warranty coverage. OR, maybe they will rear their ugly head after the warranty is up and the owner is on the hook for a big repair bill. No thank you.

Thanks for the video; I am feeling even better about my choice to buy the Cummins now!

You my friend are the blind leading the blind... How do you know Ford has a cavitation problem with the water pumps on the 6.7 PSD? Because Bill said so? :S

Enjoy your tractor engine... :W (According to Gale Banks and not me!)

I would say the fact that there is a formal procedure for checking coolant pH and a maintenance reminder that pops up on the information screen points to there still being an issue/risk of cavitation. I remember having to check for additive in the coolant of my 1996 7.3L; and this maintenance requirement is still there almost 20 years later!

I don't think that it can be denied that the 6.7L is a bit of a high maintenance engine with some serious inherent design flaws. The fact that there are so many changes to the 2015 version proves it. Hopefully Ford got it right this time and don't leave owners with super pricy repair bills like I'm sure many of the earlier versions will.

Trust me, I was a true Ford man inside and out before buying my current truck. My grandfather was the sales manager for 25 years at a Ford dealer on the Canadian prairies and my large extended family drove nothing but Fords (all different types of cars and trucks and many of them) for many years including 3 Ford trucks myself. My last truck was a 6.0L and I defended them for years including spending several thousand dollars in bulletproofing it. Then I needed a truck with a bigger cab and found that even with a 6.0L with decent reliability I was going to get hosed on resale, and I did. I researched the Ford 6.7L extensively and read common threads of HPFP failures, valve failures, and turbo failures and decided that I really did not want to be in this boat again so I decided to try a different route.

And, I most certainly will continue to enjoy my tractor engine (with no coolant testing requirement!) ;)

No bearing failure here either and this is on a stock transmission (884hp 1660ft/lbs) to boot. :B Don't try this on your stock 68RE as the internals would twist like a wet noodle :W

Interesting that this 500k mile Power Stroke did not have a bearing failure. At the time of this video only the water pump was recently changed.

Fish, I would have to dig all over creation to find it again.

But 3 percent IS the correct figure. Based from NHTSA reports on both GM and Ford with the same Bosch pump.

NHTSA didn't say a percentage, but reported 1 failure out of 1000 trucks.

Did RAM stay with the Bosch CP3 HPFP for it's inline 6 cylinder 6.7L motor?

Yes, and it played a major factor in my decision to buy the Ram.

I truly wonder what will happen with the CP4 pumps in 10+ years and 100,000 plus miles. I suspect that the failure of them will result in trucks being scrapped because the repair cost will surpass the value of the truck. It was simply a chance I was not about to take.

So, the water in fuel light is not set properly! so when the light comes on it`s too late? sounds like a defect in design!
Kind of like having a fuel tank run out of gas and still showing 1/8 of a tank left. or a temp gauge that shows normal temp, but the actual engine is overheating! how would the customer know there was a problem when everything is showing normal?

And FWIW, I`ve driven a few 6.7`s and I`m not impressed! no power and lousy mileage. my boss has a `14 F250 with the 6.7 and the best it gets on a 40 mile rural round trip is 14mpg! (minimal stops and an average of 45mph). my 02 V-10 X can get 12 on just about the same trip.
