A rubber band oil pump drive!
Simply drop the transmission and replace it every 100,000...
No thanks!

It pleases me to read about this engine. And, it pleases me even more that when, in 1964, I sold my one year old Chevrolet car to a mechanic after carefully explaining to him all of the things that had gone wrong with that car and the fixes applied. It was the only Chevrolet car I ever owned and was not only the worst car I ever owned it was the worst car I ever heard of. The mechanic just gave me a Oh Hum look, paid for it and drove off. As he was driving away, I made a vow to never, ever own a product with the name Chevrolet on it and I never have and never will. They keep on confirming my beliefs.
It?s available in the 1/4 ton as well. We almost bought a 1/2 ton dodge with an eco diesel but ran after talking to a mechanic. He said the emissions maintenance cost and the higher price here for diesel vs gas would far outweigh what we?d save with better mileage. Our province recently bought 44 brand new school buses all with gas engines. A first for here in 40 years. Diesel emissions solutions have a lot of high maintenance issues to be resolved. They aren?t cheaper by a long shot to run than gas in most cases.
Nope Dean, you got it wrong. The environmentalists want to do away with the internal combustion engine. They are going after diesels so hard because you can see the black smoke. Visible proof of the alleged damage. They have the test results. Then know that the Tier 3 standards had diesels running cleaner than gas. They don't care. They think if they can ban one they can shorty get the others. But the end goal is to stop the use of fossil fuels totally.
That is the reason they keep pushing the battery/wind/solar power thing. What they are not telling you is despite claims there are no cities completely powered by solar and wind. When it's night and the wind isn't blowing and the batteries go dead they tap into the grid. Nor do they talk about strip mining lithium for the batteries. And large areas have to be mined to get the lithium we use now. They also don't tell you about the companies that have erected wind farms, then abandoned them because of the cost of maintaining them. Lots of hidden agenda.

Diesel was a great thing until the feds got involved with their epa shenanigans.
Now it just a dead technology, mandated into poor performance and worse longevity.
They turned a good, efficient, superior simple design thing into an inefficient complicated break down mess. They made it a ?squiggly light bulb.?

Amazing the junk built by today's engineers. This thing is a failure from the drawing board.

So, Bill, doing the math, you are 70 years old, owned 1 Chevy model ? from the planned obsolescence era and now announce they are all bad? I assume over the last 55 years of running autos, NONE have broken down on you, ever. Wow. What do you recommend?

The youtube video was very interesting. Lots of technology going into the 3 litre duramax. With that said a very complicated design that i have no interest in. Makes me really worried about what is coming for our tractor diesels that are overly complex already with modest gains in effiency.

Don't blame the engineers. Blame the bean counters and the EPA.
My 1981 diesel Chevette still runs fine. Funny that in 1981, Chevy had to use Isuzu for a diesel engine. Seems today, that is still the case with the Duramax. My Chevette can get around 40 MPG at 65 MPH. Diesel nearly always costs more then regular gas now adays. The diesel advantage is lost but at least this 81 is much less complicated then the new ones. As I recall, GM only designed a few diesels in-house and they were all horrible. At least Ford did one themselves and it worked.
On the general subject of diesel - I have to ask - what is the point now adays? A gas engine always makes more horsepower and torque then a diesel when bore, stroke, and aspiration are equal. Gas, per gallon, is usually MUCH cheaper then diesel fuel. Seems the only cost-effective reason would be cost of driving? I doubt there is any savings now adays driving a diesel car as compared to a gasoline car.
Unless you plan to put 400K miles plus on a vehicle, there is no point in owning a diesel vehicle built after January 1st 2007, the beginning of DPF. Diesel has been on a downhill slide ever since. I was a GM tech at the time, when I was told in training that the LMM Duramax would burn a gallon of fuel from every tank just to clean the DPF, I though, "How stupid is that, using more fuel to be cleaner?". Then came the customers throwing a screaming fit, when they traded in their 18-20mpg LB7 truck on a new truck that got 14mpg with a tail wind. The Duramax has gotten more complicated, more expensive, and less reliable with each new generation. With no real gains in efficiency over the original LB7.

JDEM .... man, your reply brings back memories for me ...... my dad owned three Chevettes, all gas ..... I don't think I ever heard of the diesel version, I suspect they sold them in Canada though. My dad used to brag those cars up all the time to anyone who would listen (he drove me crazy to be honest) .... ha!
The last one he owned went over a cliff near Valemont, BC in 1989. Dad fell asleep at the wheel, he was 73 at the time and survived. He wasn't a regular seat belt wearer but he had it on that day thank goodness. The trip down the side of the mountain shredded the little Chevette's bottom like a cheese grater but dad crawled back up to the road and got a ride into Valemont. Crippled up a bit for a few months but he recovered pretty good.
How long have you had yours? How many miles on the odometer? A true classic, I think people have pretty much forgotten about them. Like the early Honda Civics, you could drive a million miles and never see one on the road.

What ever gave you guys the idea I wanted one?? I am just curious about what they are and who really builds them? Thanks for all the replies, I would not own a diesel unless in a class eight road tractor .
Our local school district just brought two new gas buses. They have had nothing but diesels for years. So far they have been real impressed with them not to mention the price was about 8,000 less. They are also doing better on gas mileage. The buses bodies wear out sooner then the diesel engines do so they figure the don't need the longevity of the diesels. Not to mention the problems they have had with the def. and regin on the diesels. They are thinking of ordering 6 more new gassers.

NOx is actually a worse problem with diesels than the visible smoke. The attributes that makes diesel engines so efficient (high compression ratio, high ignition temperature, and un-
throttled intake air) unfortunately make them very good at producing NOx pollutants which in turn results in smog. Gasoline engines by their very nature (the opposite of the above
attributes) are much less prone to producing NOx and therefore don't need all the complicated emissions controls that diesels do to achieve the same level of exhaust pollutants.

It has 120,000 miles on it. Sold in the USA. I had two. I finally junked the other since it got driven in the salt every winter and rusted out. I still have a 1985 Isuzu 4WD drive with basically the same engine. Chevy sold S10 trucks and Blazers with the diesel also.
Here is the one I junked with a little over 200,000 miles on it and it still ran fine. Just no body left.

You are right in that a gas engine makes more horsepower with everything being equal, BUT, you are wrong on the torque. A diesel makes much more torque than a gas engine with everything else being equal. Diesel fuel has MORE BTUs per gallon than gasoline. Diesels have much higher compression than gassers.
Also note that a diesel makes its peak horsepower and torque at a much lower RPM range than a gasser. Most gassers have to rev up to near redline to reach their peak horsepower.
Each type of engine has its own set of strong points and weak points.

Why pray tell would you want to try to use a diesel engine in light duty service ?
This is 2019, not 1970. Gasoline engines do not have low compression ratios, carburetors, heat riser valves, choke plates, points , mechanical fuel pumps etc. Diesel costs more than gasoline per gallon. Diesels have glow plugs, particulate filters, ammonia injection, EGR coolers, waxing fuel filters etc .
Diesel pickups gained popularity through the 90's, They were simple, easy to work on, cheap to fix, good fuel economy, almost bullet proof reliability and the fuel was cheap. None of those attributes are true today, not for any of the the diesel engines or manufacturers and it's getting worse.
Isn't Kubota looking at going back to gas engines on their compact tractors?
Given what I've seen of the expensive little John Deere compacts a gas engine looks pretty good. One of our hay buyers has a little 3032e with a loader. Cute little thing that does exactly what he wants - except in 4 years its been in the shop 2 times for the emissions - each trip costed him just under $3000. He didn't like it when I pointed out the two tractors that put all his hay didn't cost $3000 COMBINED - and neither hand been in a shop the last 10 years.

Drop the transmission and the oil pan at 150K. Why the **** did they put all the timing chains and oil drive on the back side of the engine so any service requires the engine to be pulled? I'd rather pull a radiator any day over pulling the engine and the transmission.
Don't let the dissers get to you, Bill. That was just how I felt after owning two VW beetles. I would have been further ahead buying the cheapest Rambler, Plymouth or Chevy. Never again ANY German engineering...for 60 years! I am down on Dodge as it was the only pickup that left stranded on the road...all because of a long coil wire from the firewall to the shakey engine. Bah! It feels good to bellow this to my fellow man!

Duramax didn't exist in 2000. You must have actually needed a semi if you were breaking a Duramax truck. The Duramax/Allison/11.5 AAM rear, is a virtually indestructible drivetrain. The LB7, LLY, and LBZ are the most reliable versions of the Duramax. Next came the LMM, which started the emissions downfall. The only think that stinks about Duramax trucks is the ball joint eating IFS. If GM would have understood the HD market wants a straight axle 4x4, I think that would have been an end of the Super Duty line during the 6.0 years, and would have put the hurt on the Cummins shipping crate Dodge called a truck during that time.

The extra btu s In diesel are wasted when particulate burn off are performed .
Diesel costs more per gallon.
The diesel option makes the vehicle more expensive to purchase .
If all you can think of is torque , you failed physics 101 in school . Power is what performs work .
Diesels have to operate at low rpms and cope with the extra stress of higher combustion chamber pressure .
The cam duration is short on a diesel or it won t build enough pressure and heat to start . The short cam timing chokes the diesel airflow and prevents the diesel from reving like a gasser and making power .
Per cubic inch of displacement a natural aspirated gasser makes more torque than a natural aspirated diesel .
The diesel is no longer a low maintenance and reliable engine .
You need to move from the 1970 s and into 2019 and quit worshiping at the diesel idol .

Kubota released a line of spark ignition engines designed for bolt in replacement of the Diesel engines .
The plan is to #1 provide an engine that does not suffer the failures , expenses and lost productivity of Tier IV Diesel engines in light duty operation by amateur drivers .
#2 a spark ignition engine for those applications where propane or natural gas is the intended fuel .
Kubota, GM and other manufactures were expecting h i l l a r y to win and the EPA enact Tier V emissions . Hence the development of spark ignition engines such as the 6.6L 401HP Direct injection gas for light and medium trucks .
In 2019 gasoline is a viable alternative given the cost of diesel fuel , cost of diesel maintaince , the cost of the diesel option and the cost of down time .
For the diesel lovers . Don t worry , gasoline engines will not take over service in shipping, the railroad , heavy trucks , heavy construction equipment, base load power generation and real farm duty tractors, combines, forage harvesters etc .
