6.0L vs 6.4L Powerstroke: Which One is Better?

Article: dustrunnersauto.com/ford-6-0l...
Unfortunately, both of these engines are plagued with various issues, and there are more problems than what we’ve discussed in this video. The important thing to remember here is that both engines have a decent amount of potential once the most common issues are fixed with aftermarket parts. At the end of the day, both of these engines were so unreliable and bad that Ford ended up developing the 6.7L without Navistar.

Your talking some good stuff man. I have a 6.4 and had a 6.0. I will recommend a 6.4 anytime for the power you will get, but they do suffer from lifters. Good info my brother. 👍

[@rustyshackleford3649]

I worked for Ford at both a dealer and then corporate level. Here’s my .02$ Take the 6.0 all day long. Most of the quirks that led to horror stories are now easy to diagnose and fix or avoid all together. Anything 2005 or later that has Not been tuned, and has had the recommended maintenance done is a great starting point. Look at the engine hours versus mileage. These engines don’t like to idle for long periods of time. do an EGR delete and you’re good. Monitor your temp deltas and FICM and it will last you a long time and be pretty economical. The 6.4 runs like a raped ape but they are a ticking timebomb. And by that I mean you will need a new engine. Not just a head, or a long block, the whole thing which is 12-15k because every runner is spoken for. The mechanics in the comments can get into more detail but usually it’s the #7 or #8 piston that begins the cascade of failure. They usually last 150k. There is no bulletproofing them. Do all the deletes you want and studs it will still blow up. Now add onto that the mileage sucks and it’s a loser. Unless you are building a race truck stay away. All those advocating a 7.3. Have you driven a newer diesel? Its loud, down on power and sucks to start in the cold. Granted it is more reliable, but the truck that it attaches to has a worse transmission, suspension, etc. Plus you’re going to have to rebuild the 4r100 anyway.

[@SOU6900]

The thing that hurts the 7.3L, or at least the ones used in the 94.5 to 97, it the fuel pump. It can't make the fuel pressure that the injectors need to get the most out of them on those engines, or thats what I hear anyway. Being a mechanic you'd know better than I would and I can't ask my uncle's opinion and he was a mechanic for Ford back then.

[@BrandonBigB956]

The 7.3 is reliable because it makes crap power.

[@adamanderson1866]

But Duramax LBZ doesn't have these problems ummm🤔 lolbut my choice is the bullet proofed 6.0

[@ZackVanMeter]

I work at a shop specializing in Light Duty Diesel, more specifically Fords. The 6.7 is fantastic after you replace the CP4 Pump and install a Catastrophe Kit from Ford before the CP4 grenades. The 6.4 is in fact a ticking time bomb. I think the interior and body are the best looking, but that engine is a damn boat anchor. If you have one and it runs, trade it or sell it for a 6.0. The 6.0 is my baby. Delete the EGR and cooler, put new lifters and updated pushrods in it, update the STC fitting, heavy duty oil cooler, New Ford factory headgaskets and ARP head studs, blue spring upgrade, coolant filter kit, and change the oil and filter every 5k and the fuel filters every 10k. For the love of God stop using the tall oil filter and tall filter cap. The 7.3 is your grandpas truck..it’ll work all day but doesn’t make any power. Buy a 6.0 and be happier.

I had it totally deleted new intake, turbos were still good so we just cleaned them up and put a 4" exhaust. Mild tune FASS fuel system and the thing is amazing. Realistically i will be very happy to get 200k additional miles out of it. I still think that I am way ahead financially from buying a newer truck. Besides that I love the looks, ride and transmission. Hope you guys have great luck with your rigs.

08 6.4 F250: I was terrified by all the reviews of the 6.4 but couldnt pass on the deal i was getting. I got it at 46k, still have it and want to keep if for as long as possible. In the 1st 2 months I had to replace the egr valve, both thermostats and was noticing I was burning through a lot of coolant due to the dpf. At 50k I did a full EGR/DPF delete ( 90% of the truck critical failures come as result of either the EGR or the DPF Messing things up internally) and ordered aH&S Mini Maxx tuner for it. I stay up-to-date with my maintenance currently have 88,000 miles. I deleted everything and installed the tuner over a weekend and have had zero problems since deleting. The truck performs better, sound better and operates without a flaw. There are definitely easier engines to work on, but it's not as bad as everyone makes it out to believe.

Plus I purchased a SCT X4 Tuner/Monitor to keep track of engine parameters. It is a solid runner now. I think all that was easier than replacing bottom end items in the 6.4, so I would have to say the 6.0 is a better choice for fixing the issues.

Talking about 6.0 having weak head bolts and that being a big problem yet its said you need to bullet proof which doesnt pertain to headstuds but rather the oil cooler and egr cooler? To my knowledge the tty bolts are ok for stock and slightly turned up applications but when the EGR ruptures from lack of coolant caused by a clogged oil cooler and sends coolant into the combustion chamber is when the bolts are usually compromised. The 6.0 isnt a bad motor, which the video state that its a decent motor but you have yo understand the issues on it and which steps to take for your 6.0

After working at a Ford dealer which had two shops, one for cars and one for trucks where I was a tech in the truck shop I can easily say the 6.0 is better. When I first started working there I asked all the other techs what they would own. Most said if they could afford a 6.7 they would buy one, others said a 7.3 if they could find one cheap and rust free whether or not it ran. When it came down to the 6.0 and 6.4 not a single person ever said they would own a 6.4! In fact two guys I worked with actually had 6.0s lol. As far as work that I have done on them usually the 6.0s had oiling issues or needed fuel injectors. The 6.4s always came in needing an engine after the owner neglected to change the oil in time and the truck "made oil" which was thinned out by fuel and either made the truck run away or wore out bearing material prematurely. All in all I tell all my friends and customers, a 6.0 Will be a decent truck with some time and money but stay FAR FAR away from 6.4s

[@michaelchan8915]

HA! I'm glad I'm not the only Ford dealership technician who thinks the 6.4s are ticking time bombs on wheels. It's not a matter of IF but rather WHEN that expensive repair is going to happen.

Like I said they all have their flaws regardless of what brand or motor. Personally I would much rather have a 6.4 than a 6.0. Maintenance goes a long way and I've seen both motors reach very high mileage and are still going because of the right preventative maintenance and upkeep. Simple things like EGR delete, intake, exhaust and mild tune really makes the 6.4 a completely different animal. That as well as fixing some fuel system issues, body mounts and rad problems it becomes a great reliable motor. Same can be said for the 6.0 by doing some of the same and also fixing it's common flaws. They can both be made reliable but if your looking to make any kind of power the 6.4 is certainly the way to go, not to mention the 6.4 is still the best looking body style made in my opinion.

My 7.3 just keeps running and running and other than changing to 1.5 injectors and installing a +140hp tune (which at max makes the transmission shift very hard) it gets 20mpg and will pull anything, including your truck via chain if you park it in my way.. i can go through any mudhole that anyone else can, and winch you out if you don't make it. Still getting 20mpg.. and I have less than 10K in my truck, new tires and all. Only downside is starting cold..

I race a 6.0 and every shop or racer I talk to says the same thing “almost every 6.4 we get needs a whole new motor” but the only thing 6.0s are coming in for are head studs and deletes. Not new motors.

[@alvinhyman6838]

Seing this is an older video, the 6.7 has it's own problems that are just as expensive to repair . The 6.0 and 6.4 have to be deleted to be reliable and both need certain areas that if addressed make both of them good . The 6.4 is a beast of power that can run fine tuned between 5 to 6 hundred HP making as much or more than the 23 6.7 high output. My 08 6.4 has 240,000 miles and gets 19 MPG as a daily driver on the highway empty gets close to 30 MPG. Pulling my 4 horse with living quarters trailer around 15K I get around 17 MPG so I will stick with the 6.4 as being the better of the two!

My boss gave me one with only 144k(kms) He was starting to have enough of the breakdowns and he was just about through that struggle as I saw that it was head studded and had egr delete after I was working on it for him. I put a new ficm in , and changed one injector and rebuilt the turbo for him as the vgt was getting stuck. He liked how much research I have done for the 6.0 and knew if anyone would keep it going it would be me. I still have to change or rebuild the fpr as it is leaking, do a coolant filter, rebuild the passenger side oil rail and get a tuner to monitor deltas. All just for piece of mind as I've already rebuilt the driver side oil rail. It runs good but has smoke on start up, so I'm thinking the other oil rail is loosing pressure.

You don’t really need to go crazy on mods if you can delete or varying by states emissions EGR upgrade/bypass at bare minimum truck can and with a good on time maintenance schedule last 900k miles bottem end on a 6.0 is good for about 1.2 million miles After EGR cooler next thing that’ll give you trouble is the FICM just get a SWAMPS 58V ficm and then the turbo but if you got the EGR deleted turbos will last significantly longer btw with a EGR delete put a SCT tuner on it so that you can bypass the EGR code and your check engine light will work like normal next thing to do if you do EGR FICM and turbo is arp head studs and or oil cooler replacement/upgrade

[@justnsaliga8518]

With a completely stock 6.0 and not in a northern climate or severe duty work loads you can expect to see 200k before major issues pop up like FICM loosing voltage clogging or clogged and or cracked EGR cooler it ruins your cylinders overtime, clogged /stuck turbo typically speaking though diesels once you build it well are pretty cheap to maintain if it’s been built well and provided has good maintenance schedule a set of injectors which fail mostly because your ficm goes bad or improper oil or old oil too long injectors last anywhere from 200-400k miles and if I recall it’s probably the most expensive part about 1200 dollars for a set

I plan to put over 600k on the truck in the next 10 years - the truck had 150k on it when I got it - and it just went over 200k this week - 50k in 10 months). After having the truck worked on by Powerstroke Specialty; it's been a dream to own. With no EGR, no DPF and no DEF. ...I idle the engine with nearly no worries on cold DC days - and I also get to drive lefty DC people crazy :-)). I 100% change the oil every 5k (so once a month), I always use Rotella T6, Ford filters, Archoil Friction Modifier, Fuel Treatment and Fuel System Cleaner (you can get a kit on Amazon for $95 - good for 5k miles). Change the fuel filters...BOTH on a 6.0...always at 10k. ...as US diesel is nasty. Drain and fill your coolant every 60k (never more than 60k miles and never flush - just drain and fill - use ONLY Ford VC-7-B Gold and ALWAYS a new Ford radiator cap). Change the transmission fluid & filter at 60k also (no need to get fancy - again - just drain and fill - Ford filters, Ford Mercon SP fluid). I also installed a Sinister Diesel oil and coolant bypass system (works ok good) and their Blue Spring kit. With a Loony toon (and all the other sh*t :-))...I get right at 19mpg driving 80mph.
