    as a automotive technician with 18 years of experience ( i don't couth the years i spent sweeping floors or helping techs thru the years) all i heard was "THIS IS GOING TO COST YOU MONEY WHEN IT BREAKS. THIS IS EXPENSIVE, AND GOD HELP YOU IF THIS GOES OUT AND NEEDS TO BE REPAIRED. THE FUEL INJECTORS ARE ABOUT $500 E PIECE TO REPLACE. THE VARIABLE OIL PUMP IS A INDUSTRY LEADING JOKE IN THE AUTOMOTIVE BUSINESS. 400+ Lbs OF TORQUE FOR GOING TO THE MALL, AND A HIGH PRESSURE CAM DRIVEN FUEL PUMP FOR WHEN YOUR IN THE McDONALDS DRIVE THRU. THIS IS NOT THE TRUCK THAT CUSTOMERS WANT, IT'S THE TRUCK THAT WE, AS ENGINEERS ENVISIONED. AND WE'VE FULLY IMPLEMENTED WHAT WE WANT TO SEE, AS OPPOSED TO WHAT THE ACTUAL BUYING PUBLIC WANTS."
    I have seen time and time again how the car buying public doesn't give a rats ass whats in the vehicle, how it works, or what it's made of. They just want it to go forward and reverse, and look nice doing it. But when something goes wrong.....it's usually US (technicians and the shop) that get the blame for the immense cost of repair. I did a repair on the seat vibrator on a 2014 Suburban that went out when going in reverse. It lets you know when your too close to an object. Total cost: $1,400. Do the air ride rear shocks and the front Variable Magnetic Dampening shocks go bad? $2,600 for new rear air shocks, compressor, and front struts. The vehicles being built today are not built with longevity in mind. They are build with bells, whistles, and the newest Apps that let you control certain functions thru your phone. And when that shit breaks, so does your bank account.
    This truck is a Easy Pass for me.

      I'm not sure. The consumer doesn't care how it does it, as long as it does it. Seems people want it all in a truck now. Low end torque, high end horsepower, runs quiet and smooth, and delivers good MPG. Meanwhile the EPA/CAFE and a host of others want it to not only get good fuel economy but burn so clean. Here is the result. No, vehicles are not built for longevity but due to increased warranties and lemon law requirements they are being built better and lasting longer as a result. I do believe that the average consumer knows less and less about their own vehicle and how to care for it properly while becoming increasingly demanding with an entitlement mentality that the manufacturer is responsible for the vehicle as long as they have it on the road.

    Nothing to clean up intake ports clogged by PCV /EGR deposits wich will ruin the efficiency over time...
    Customers don't demand on variable oil pressure...

    • @lees.4084
      @lees.4084 5 років тому +1

      You can blame ever-tightening government mandated fuel economy standards for all these little tricks to squeeze out every last bit of efficiency.
      Unless, you'd rather pay the hefty gas guzzler tax, AND suffer the higher fuel bill as well?
      But then you'd be bitching about that....
      BTW, EGR is fairly rare on gasoline engines these days. The catalytic converters have taken over the task of NOx reduction.
      And a properly designed PCV system draws very little oil/oil vapor back into the engine these days.

I will take 5mpg less if it has a solid motor that's make 20 less HP but works every day and has little to no down time. Down time cost way more than fuel. No truck no work. It cost me about $65 to start my truck and leave the office but not working for a day could cost me $3000 or more. I'll take. My 07 ram has never been to the shop other than normal maintenance.

      I know all too well what work trucks are bought for...
      It doesnt make what I said any less true.
      You may not like it, but the federal government mandates fuel economy standards, and the auto makers have to come up with such technology to meet the standards.
      Fortunately, this new 6.6L engine isn't going to use AFM, or Stop/Start....
      It will have VVT, but that's a reliable system on these trucks.
      The variable oil pumps likely wont ve a problem either.
      It's a simple system, and the technology has been proven in automatic transmissions for decades already.
      So stop with all crying and moaning.
      So, you bought a Ford, with an engine with FAR more moving parts in it, more valves, rockers, twice as many cams, and twice as many timing chains, long chains that require lots of elaborate guides, with oil pressure actuated tensioners.
      You got damned lucky it only had to go in for spitting out spark plugs. How much downtime did that cost you?
      Those years F150s were notorious for their transmission failures too.
      And then you tell about how you like simplicity??? GTHOH
      BTW, most people making that kind of money typically have a backup truck they can drive if their primary one braeaks down....
      Are you so I'll-prepared that you dont have another truck to fall back on?
      And if your 07 Ram hasn't had any issues, that's just amazing...

      @@lees.4084 Guess you read internet trash more then you have real world experience. The GOV does not mandate anything. They do award CAFE "points" though. Every vehicle produced uses these points up. The amount is based on a number of parameters one of which is MPG. Saving .1 points on every truck means they might be able to produce 1 more truck for example and therefor make more money.
      I know many 02-06 Fords (all gas) that have been working since day one with little to no issues other than scheduled maintenance (they tow, plow, and haul). But if you know common issues you can prevent some of them. Like the spark plugs on my 99 or the stupid 2 pieces plugs on early 3V 5.4. Or harness failures on my ram (little bit of spay on electrical tape on problem connectors). But things that require software to run properly you cant (or at least real hard to) prevent failure until the manufacture gets it right. You bitch about chain tensioners, why? Most motors these days are overhead valve. I think (like your electrically controlled oil pump) are proven to last. As far as the down time with my Spit out plug... 4 hours in my own own shop the day after the issue, drove 500 miles on 7 cylinders with a rubber stopper in the valley (drilled a whole in it and put a long bolt sticking up so i could grab it) and the injector unplugged. Also, when your a transporter and your 100s or 1000s of miles away from home, having a spare truck does nothing to help you. My trucks need to be reliable on long trips of 2000-5000 miles at a time. I do ALL scheduled maintenance in the owners manual and I've never had an issue. I have 4 trucks (99 f150, 12 f350, 07 ram 2500, 10 ram 3500) 2 for short or light loads and 2 for heavy loads. All gas (because if you do the math its cheaper than diesel). I can get 300k out of a gaser then replace the motor with rebuilt for $2500-$4000 depending on year and get another 300k. My newest truck is 12 f350 with a 6.2. I knew this year had issues with throwing rods so I found out it was a main barring oiling issue. So I had my local put new bearings in it at 70k in 2014. Yes, it was 2 days of down time and $800 but better than $4k and 2 weeks down. But other than a sunroof issue NOTHING BUT ROCK STEADY like my rams. I'm not a Ford or Ram fan boy but it seems GM has implemented the "lets let the computer control it" attitude. I'm not a fan of that, not in work trucks. I loved the 99 and older GM trucks. Hell, my dad has a 14 GMC 1500. He had to replace his ECU because the external Baro is built into the the freaking computer. WHY? No other manufacture does this. They might have one in the motor but it can (in some cases) help in fine tuning the fuel mixture for a tiny bit of extra MPG but the cost to the customer is not worth it. GM benefits cause they get .5 CAFE (made up number) points though.

      I do agree with you about diesels not being cost-effective in many, or even most cases.
      Just the higher diesel fuel prices eat up most of the MPG advantages of them.
      Not to mention the much higher purchase, maintenance and repair costs...
      I know Ford has had plenty of timing set issues, plus cam phasers (VVT) issues.
      And yes, many engines are OHC or even DOHC these days, and most dont have major issues with it, but some do.
      On a V6/V8, it does add substantially to the number of moving parts involved, something GM has avoided with the LS V8s, and something Ford is rediscovering with it's new 7.3 gasser...
      My company just upgraded my work truck to a brand new GMC Sierra 5.3L yesterday, love it...
      And no, a backup truck wont do you much good a long way from home, but it can help you get back on the road faster if you are looking at prolonged repair on the truck that did break down.

    • @Broadpaw_Fox
      @Broadpaw_Fox 5 років тому +6

      It's actually an awesome idea. Lubrication is critical in an engine, and temperature plays a huge role. Once oil is up to operating temperature, things are good (that's what they design the system around). But if the oil temp is low then the oil is thicker than it should be - this raises the pressure. Pressure does not lubricate - flow does. Pressure drives flow, right up until the cutoff point where the bypass valve opens. This is why most of the wear in engines happens when they're cold.
      On the flip side, when you work an engine hard, the oil gets hotter than the ideal operating temperature- this thins it out more. Now you have more flow and less pressure- and this can also destroy an engine. But if you have a system that can vary the flow of oil and a high enough pressure limit you can make sure the engine is properly lubricated much more effectively.
      With all that said, all I heard when he mentioned it was the next big recall/maintenance debacle to hit the news. I just don't have faith that they've engineered/tested this well enough just based on their track record. Sorry GM... but I do think this will become a standard once the bugs are ironed out. :)

      From what I understand, GM has had a fair amount of success with optimizing cam and injector timing to get a little bit of gas back behind the intake valve during overlap phase. While some earlier GM engines with DI had issues, I think they have a stronger track record than most in more recent times. This set of mitigating solutions is patented, so that would explain why others are doing different things.

    The new Ford 7.3 definitely wins on simplicity and more than likely on horsepower. Fords current 6.2 is rated 385hp/430tq which isn’t far off what this new 6.6 is rated. Unimpressed

      @@toddjohnson7133 the cleveland or windsor never stayed together when abused. Nor do either of them make even make 4.8 ls power factory. Also gm ls based engines are the first factory engine to incorporate 6 bolt main caps unbelievable flowing cylinder heads. A windsor or cleveland would never ever stand the beating these motor will put up with factory. Not trying to push your buttons but if you look at both cutaways and really look they are identically designed. The new 7.3 is the only ford motor that incorporates the 6 bolt mains and the lifter tray design.

      @@loganpenland6568 "the cleveland or windsor never stayed together when abused"...this is a news flash to me...and the rest of the world. So we should disregard the fact that the Cleveland style Ford engine forced NASCAR to allow GM to run the SB2 twenty years ago. Because the Gen 1 SBC was simply outclassed. The SB2 was the first engine that competed that was not a factory based engine design. Huh? This is stock car racing? Ford was made to soldier on with a Cleveland style engine until '07. How do you explain that when there is an engine build-off with big $$$ on the line either Kaase or Bischoffe shows up with Cleveland or a Clevor and cleans house? No LS or BBC or SBC is able to put up the numbers that the old Ford small blocks can. Hell Kaase won the last Hot Rod contest with a Y-Block Lincoln. The LS is not to intimidating. The gen III hemi is much more efficient. If there was a modern pushrod engine to copy....that would be the one. 6 bolt mains is also old news. These have been on Modular Fords since the 4 valve head....old news.

      @loganpenland, you are VERY uninformed on Ford engines, Fords had cross bolted mains in the 60’s and still have them in Cobra Mustangs, hope this helps you a little!
