TUNING IS KILLING YOUR 6.7L POWERSTROKE

[@stanleyzylowski2414]

Hi Bill, you likely don't remember me but you replaced head gaskets on my 6.4L. I was likely the last job you did in 2013 I picked the truck up late on Christmas eve. I was the old man you are talking about here. Had an H&S tuner. Always drove on setting 1 (Stock power) and for sure always towed my big camper in 1. But I was messing around with different settings and I forgot to change it back to 1 when I hooked up the camper. As I topped Mount Eagle I felt just a little sort of twitch. Stopped for the night and the next day coolant was low. Topped off and continued on the trip. Right about then I noticed the tuner in setting 2 and figured it out. That truck towed that big camper (17,000 pounds) out to western Montana, up to Glacier NP, back to Yellowstone, and back home, all after blowing a HG, I just kept topping off the coolant. Lots of people ragged on the 6.4L but I thought it had great power. Two months after I got it back from you a drunk old woman hit us down in Fort Myers and they totaled the truck. I got a new 6.7L and proving there is no fool like an old fool I have it tuned. Tune is STOCK POWER, EGR OFF, DPF DELETED. I think that is a safe tune. but I'm 80 now so if it blows it blows.

Your concise words on early cylinder ignition is my envy. Having begged with people to understand the multi-injection algorithm (program) PRIOR TO THE PRIMARY or MAIN injection is so key to knowing how these computers and the piezoelectric injectors can get the extra fuel in but cannot stop the physics and chemistry of compression ignition PARTICULARLY EARLY and sending that force down the rod to beat the bearing half and squeeze that oil film away damaging the bearing..... getting OWNERS KNOWING ALL THE FUEL IS NOT INJECTED IN "ONE SINGLE SHOT" is key for them to knowing that EVERY TUNER MANUFACTURER is managing BOTH Pre and Main Injection Programming...

[@wtbman]

Thanks for this explanation. I recently had my 6.7 tuned just to support the 2015+ turbo (mine's a '13) and I've been having frequent regen problems, even after a full flow test certified DPF cleaning. I decided to upgrade the turbo since the exhaust manifold studs started popping off and have read the stories about the early year turbo failures and wanted to bulletproof the exhaust system. The torque converter locks up earlier and shift points have been changed. I'll be sure to check if it's lugging too much or just try to keep the rpms up and see if that helps with the regen intervals. I'm to the point I may need a new Powerstroke doctor to fix it up since the shop that did all this work wants to avoid any responsibility...

[@jasoncooper331]

The frequent regens are from bad tunes.

Thanks for this information as I am that older guy with a 6.0 and a tune. I use the tune for good fuel economy when running unloaded and switch to a mild tow tune when needed.

[@MrTheHillfolk]

That's a thing with even stock cars these days,with small displacement relying on the turbo ,and then having crazy compression ratios like 10-11-12:1 on a gasser. Unheard of compression and boost levels and at lower rpms , if something is slightly off it's gonna pop. On a side note ,my manager at work has one of those little ram vans ,every time from a cruise when you tip into it you'll hear a little spark knock. That's kinda telling me a few things, the stock tune is aggressive , and keep doing that for 100k and watch a piston fry up.

Great video, I'm originally from the Pacific Northwest true diesel truck land. Moved to Phoenix about 18 mo ago. The heat down here is tough on my 95' F250 Powerstroke. I'm a CM for a large home builder so in the summer we spend hours a day in our trucks. All the idling is really hard on bearings I noticed one day my oil pressure was lower than normal. Still in a safe range but not high like usual. 250,000 on the truck and found my oil cooler was leaking. There's a video on a new 6.7 that had very low miles but approx 5,000 hrs of idling! Oil change history was good for the miles but the bearings were toast! Bottom line know your truck and don't abuse it.

Excellent information. Not a Ford guy but what he says applies to all brands. I blew up a mildly tuned 6.5 Chevy by lugging it while towing. Now I have one with a better turbo and more fuel that I can tow much heavier with- but I keep the rpm above 2200 at all times (usually 2500 and up).

[@georgesrisomsak9650]

Damnit... Guilty of this on the ol 03 7.3. I don't lug it hard(4r100) but I do drive at low low rpms. And I run the third, from the all out tune. My bearings gonna slip out in the middle of the night, sneak in the house right into the ol bedroom, and put it's shavings in the toothpaste and on my TP likely if I don't knock it off I feel. Im praying to the Ford gods to release the bad juju I've imposed with this "hammering" and let me spin it for another few hundred thousand miles. She runs like a top at 296k, still on factory injectors. Starts at -2 like butter too. Crazy how it works when you maintain them. Fresh ZD-11's and a stancore relay, probably better than new.

I never owned a power stroke engine. I really appreciate this u tube channel as I believe they are very good at what they do ..I remember many years ago in the forums for what that's worth about timing and the effects on bearings , I run more timing in my old diesel as it gets better mileage. I was also wondering about the wrist pin bushings ect . These things are I assume based on the size of the components and the load imposed on them . Timing can also stress the head gasket to a failure... i alway like to let the old engine get up to temperature before i load it up . Thanks for the videos and the information

[@OOMAN]

I’m running the Banks Derringer programmer on my ‘19 F-450, with 2 gauge pods monitoring all the temps. I like that it is adjust on the fly. More power = lower fuel economy. Only time I turn it on is getting on the highway or running up some big hills, when I’m pulling my 20k toy hauler, or I have a heavy load on my flatbed trailer. Has plenty of power in stock setting for most other situations. Also gets best mileage in stock setting. Best thing I did for fuel economy was put the Ram Air system on it. Gives me 10%-15% better mileage.

[@jensenleblanc]

Don’t turn the power up when towing. That was the main point of the video. Ignition timing at lower rpms… Be sure to keep it around 2000-2200 rpm when going up steep grades.

[@ironmike742]

Very good video Bill. People don't realize that the whole time the engine is running it is trying the shove the crankshaft right through the oil pan. All you're doing is multiplying the leverage when you get too crazy with fuel, timing, and overboosting past the limit it was designed for. Very good video.

[@CutlassSupreme6969]

Thanks for the advice and your wealth of knowledge, Bill.

[@Erichhh]

PCP - Peak Cylinder Pressure. Timing affects it, as does fuel rate. Every engine is designed to a PCP target, and nearly every tuning change bumps PCP above that limit. Engines are also designed with Safety Factors for the individual structural components. Some of these are easy to add extra margin to (block), but others have a lot of competing targets (con rod wants to be as light as possible, so it has a smaller safety factor. Head needs to be cooled, so it can't have a large factor of safety because wall thickness competes with ability to cool it). There's always a "fuse" in the system, typically the head gasket (6.0 lifted the heads and puked coolant out of the reservoir). But if the fuse is elsewhere (as in the 6.7), the failure mode can be more severe. 6.7 is robust structurally, but (as you expertly pointed out), the combustion force can literally squeeze the oil film out from between the bearings and crank journals, resulting in metal-to-metal contact just like a dry start (except under full load). The only way to increase capacity in the bearing is to make it wider. And bearing area is another tradeoff - more area requires thinner crankshaft webs (wider bearings) or a heavier crank (journal diameter increase). So the solution to achieving more power safely is to increase the area under the combustion pressure curve, without increasing the peak pressure above the limit.

[@TheCarnivoreCannons]

thank you for speaking from all of your years of experience with honesty.

[@arc00ta]

Pushing the engine harder than intended is always a gamble. In my tuned vehicles I send an oil sample in every couple of oil changes to track what its doing. Keeps my mind stress free that there is no forbidden glitter or reynolds brand bearing foil going on.

Just buy an oil filter cutter, or get a System 1 oil filter, and check it yourself EVERY oil change.

Cylinder pressure 101. I find the stock scorpions are damn perfect bone stock. The only thing I would suggest is tuning the trans shift schedule to lower dynamic cylinder compression...and an aftermarket lift pump and absolute 2 micron cat filter system.

[@davidgraf197]

Great video! It all boils down to leverage. It’s harder to turn the crank when it’s closer to TDC. Once it passes it all goes to the wheels!

[@ctdieselnut]

I was waiting for him to say something like this. Steve dinan, founder of dinan engineering (bmw tuner/race car builder) did a good video about tuning on the drive channel on yt, heard him say 'we try to time an engine so peak cylinder pressure occurs at the optimal crank angle. That's where the engine is most efficient at making power.' What angle is optimal varies with rpm, fuel type/octane rating, flame front propagation in combustion chamber, etc. There is always a sweet spot, and anything earlier is too early, anything later is too late, and you lose power. Or worse, hammer your bearings to death, or in a gas engine, cause knock with too much advance. It gets even more complicated in diesels with multiple injection events per cylinder per firing. In short, don't let just any Yahoo tune your truck.

[@j.b.216]

Just like peddling a bicycle.

[@michaeldunagan8268]

Only tuning I’ve done is for the larger tires. It’s plenty powerful without adding anymore.

[@michaeldunagan8268]

Larger tires without compensating the extra diameter of the wheel assembly and the axle or transmission brings the vehicle closer to the lugging range as larger tires act like shrinking the ring gear relative to the pinion gear.... I'm just saying....

[@stevenmitchell6347]

The only Powerstroke I would consider building and tuning for power is the final edition of the 7.3 that ended in 2003. I currently have an '03 6.0 w/an '04 engine. The 6.0 and DPF Powerstroke isn't designed to be overboosted....and live very long. Economy tunes and Tow/Haul tunes can be more efficient AND powerful within the limitations of the OEM parts. It's the high-performance tunes that kill ALL diesels, especially the Powerstroke, due to its inherent design flaws. I'm not a mechanic any longer and am a retired Industrial Design Engineer. My discussions with International and Ford/Navistar engineers were very enlightening as to the flaws and WHY they exist. Suffice to say that marketing, sales, and the CARB/EPA were camped out in the engineering departments, making unreasonable demands that resulted in the product we were sold. Thank you for your insight.

[@CITIZENSDOGE]

FYI, there is no explosion in the cylinder during the power stroke. There is a controlled burn of the fuel and the oxygen in the air. What is left over is super heated expand nitrogen the piston squeezes the expanded nitrogen and pushes the piston back down.

[@dustinbieri9786]

Ok so I kinda call bs. I work at a Ford dealer and I'm the main diesel tech. Been at the dealer since 04 as a diesel tech so I've seen them all. The real issue here is the epa. Most every truck we work on is bone stock. This is very very common for 6.7s to hammer the bearings or spin the bearings in completely stock trucks. It all stems from the epa wanting fuel milage (aka 6 and 10 speeds with 1400 to 1600rpm pulling on the highway), the epa mandate to pull all of the good things like zink out of the oil because it's bad for the dpf. And then we have the dpf and scr systems that make these things breathe through a dirty straw. I've seen way more issues with main bearings from oil type than any tuning. Yes don't get me wrong tuning can kill any engine. But in the 6.7 tuning is such a small spec on the map compared to what's actually killing the bearings.

Note: when towing if not on flat and level the the cruse control can over load the mains they will rotate and then no oil to rods. Have seen non tuned engine failures. ( Ford senior master Tec.)

[@michaeldunagan8268]

My 2000s trevan had a switch on the turn signal lever that if the vehicle was either hauling heavy or towing one was to Preston switch. My guess was that the system raised the RPMs at which the transmission would up-shift to the next gear in order to keep the 4.3L V6 Virtec engine from lugging.

[@BrandonBigB956]

Thats why I lock out the higher gears when I have a big load behind my 6.7 Cummins. Running a 30hp tune from a smarty and never run the higher tunes as they all start messing with injection timing to get power and that's not good for longevity.

[@davidnation4437]

Great video, Big trucks and cummins drivers can lug a little more, because they are in-line and not V engines. gives them a lot more room for wider bearings = more surface area, more oil film area. I’m sure it won’t matter as much in stock form.

[@andrewrivera4029]

I really notice the engine in low RPM’s when I have the cruise control on traveling at 70 MPH under load and I hit a hill the cruise control will not downshift til it has gone 5 MPH below the set speed. I’ve begun giving it gas early to avoid the slowdown, didn’t know that was also bad for the bearing too. Thanks Bill and merry Christmas to the whole Powerstroke family!

Almost 50k miles on my 16 6.7 fully deleted and tuned, with 25k of that being full bolt on with non-vgt turbo swap, mpd piping and swap kit, airdog lift pump, etc. Shes been absolutely flawless for me. Tuning does not kill these trucks, the idiots behind the wheel do. Treat it like a truck, use the proper tuning for what youre doing, and be responsible. Also its a V8, dont be afraid to rev it out a bit, youre gonna do more damage trying to lug it at 1800rpm than letting her shift at 3000 to alleviate cylinder pressure.

[@RobVarley]

Awesome video. Thank you.

[@prestonhayden8283]

I feel so guilty 🤦🏼‍♂️ bought my old 7.3 idi @385k and beat the crap out of it everyday for 2years and when she’s rolled over 400k we bumped that pump up and she’s still getting the beating 🥺 love her she’s the strongest old girl I know thank you international can’t believe she’s been beat of for 30 years and still wants more she runs so good I don’t even plug her n on cold nights and she gets up everyday 😊 not bad for ah 30 year old with ah drinking problem ❤

As a owner of a new 2022 6.7 ps, I appreciate the info, keep rpm 2000!!! Ten 4

[@salmonaco007]

Hey Bill that engine is making 475hp 1050 torque now look at a caterpillar 475 hp the bearings are twice the size 😀

[@454budman]

Yeah but whats the torque of the cat? The rotating assembly is probably twice the size of the 6.7 ps. Just because it makes the same hp doesnt mean its made the same. Thats like comparing a tractor engine to a truck engine. They are made different for different jobs.

Yea a 475 truck engine is gonna probably be set up for 1750 or 1850 tq usually. And there's the difference between light duty and heavy duty engines

same thing for constuction. One day its dead, next day we need to hire more people.

[@TKHOTSHOTU]

Hi and thank you so much for your content. You are making our trucks last so much longer. You mentioned tuning could be good for fuel milage. Can you recommend a tune for increased mileage for the F-550 and up that come detuned from the factory?

[@georgehenry3384]

Always a wealth of information! You are a diesel savant!

[@joshuawhite5979]

Love your informative videos where you share your knowledge

[@chevyblock550]

I've heard of this happening a couple of times in the Cummins for the Ram. Those engines pull so hard at low rpm but it is very harsh on the engine and causes the trucks to run so rich which is why they smoke so much more deleted compared to other trucks.

[@huskers1278]

Both my companies rams are deleted one 5500 and one 3500. The 5500 is getting a new engine right now because it decided to delete cylinder #6 while pulling our backhoe a month ago.

[@guardrail2897]

@@huskers1278 How many miles before it deleted itself?

[@jensenleblanc]

Great video and explanation Bill! Is the 20+ motor less susceptible to this problem than the previous motors due to the revised rods, piston, and lower compression??? The new 10 speed loves to keep the rpms way down, I think the main caution would be when towing to be sure to downshift on long grades. Hope you’re doing well!

[@seijirou302]

It's the same for the 20+. The rods piston and compression aren't really factors. Bearing size (width) where wider is better, and then just timing are what do it. Bill touched on it just briefly but the key thing of this failure is metal fatigue in the bearing itself. Take a coat hanger and flex it back and forth it will get weak and break, that's what is happening to the bearing. The hammering is flexing the bearing and after a while the metals in it start to fail. Can't even solve this with some kind of better oil, because it has nothing to do with lubricity or film strength. Even if an oil had perfect film strength all that means is the forces are fully transferred through the oil to the bearing bending it instead of pushing oil out. You could theoretically help this with a weaker rod because a weaker rod would flex and give more, absorbing more energy and reducing what gets to the bearing. But imagine the outcries if Ford installed weaker rods. The reason higher RPM helps Bill didn't explain, but it's because the flame front of combustion always has the same speed. With higher RPM the piston and rod will get farther away from being straight up and down at the moment of peak cylinder pressure because the piston is literally running away from the flame front faster. Bill is correct, when increasing the forces in the cylinder like this you either need to use more RPM to keep the rod angle appropriate, or less timing. The lesson here really is understanding that tuners go by the dyno and adjust their tunes based on the output measured by the dyno. What they aren't doing is tuning an engine and then running it for 2,000 hours at load to see if their tunes create failures in the long run. You'll see things like "early lockup" in tunes, run away. People like that because it really will make the truck feel and drive better and get better mileage, but it's also much harder on the engine's internals.

[@sav300]

@@seijirou302 what are you talking about?! I’m mainly referring to your comment of “run away” to “early lockup”. Do you even know what that means??? Do you understand what that does? You were pretty easy to follow at first and then it started to ramble like you regurgitated something you heard. Then you make that comment and it’s obvious you don’t know what your talking about. Don’t give advice when you yourself don’t know

[@mysock351C]

With the 6.7L, is the design itself not also an issue? From the much narrower and smaller rods (Edit: The later model ones seem to be more reasonable as far as size) it seemed as though Ford was banking on the injection strategy to keep the peak cylinder pressures down by spacing out the combustion over multiple injection events. Since the pressures are lower, so are the forces, more like a gas engine with it spaced out over the work cycle rather than as a sharp impulse like old-school mechanical diesels. These seem to have fairly small bearings as well. Probably works ok with the factory tune and helps fuel economy by keeping the rotating mass down, but I can see why they would fail when tuned more like a traditional diesel. In a way the bottom end is somewhat like what you would see with a gas V8.

[@jadesmith8512]

We have a 6.7 at the shop now. This is the third ive seen. Same problem just a little worse. It spun 3 main bearings and 4 rods. It is stock, not tuned. I think the stock programing is also to blame. They want the rpm low and converter locked for fuel mileage and to help control transmission temperatures when towing. I've talked to another shop that specializes in just powerstrokes and he is seeing alot of bearing failures around 200k miles or less. The other two trucks, one was tuned, and the other was a oil field work truck that was not tuned

[@bobbywalter5320]

Yes....trans shift scheduling and high end oil will be a big benefit. I honestly think they want these trucks dead by 250k so people buy new stuff. Look at the 7.3 gas engines. That oil system is a joke. I am at my fill with ford. They are turning me into a hater. I am an oilfield guy as well.

[@CarlosRodriguez-hb3vq]

I drive a stock 2011 with 170k and Blackstone tells me I’ve got aluminum, probably from bearings, in my oil. I use good oil, change it regularly, and drive normally. I don’t know what else to do but wait for it to fail and get a long block.

[@travisthiessen3570]

Just sold my 2014 with 306,000km that was tuned and deleted from day 1 then I installed a full H&S non vgt turbo kit at 60,000, 2015+ cp4 and custom tuning. Zero issues and I drove it like a race car, pulled a 40’ gooseneck and my 38’ camper 🤷🏻‍♂️

Ok I'm one of the old 5.9 guys I have a 24 valve 5.9 with compound turbos and it is a tow rigg that will tow anything I put behind it. But if I'm pulling a pass or the loads heavy it still get pulled down in gear appropriately. No point in overworking rings pistons and rods. Keep it cool.

What are your thoughts on the new fuel water separator/secondary filter that SPE came out with last week? It uses CAT filters and replaces the stock unit in front of the tank.

[@410ytlmustang]

If you get rid of epa, which has no right to make law you solve the biggest problem.

[@disgracebook5708]

Even the new 6.7L (stock tune) with the 10R140 (stock tune) lugs when shifting from 4 - 3 when in tow mode (1500 rpm). Sucks. Forces you to hit manual to force a downshift to raise rpms.

[@jeepindave5464]

As an engineer this is a good video. I sold my lbz duramax and a tuner never touched it. Slow and steady.

Do you know what weight oil he was running? Bearing failure seems to be more common on trucks running 15w40, especially if they ever see cold temps.

Closer bearing tolerances on the 6.7. 5w40 is crucial on these engines!
