4.5L Duramax For 2010- New Pictures?

**ccole** · 12-27-2008, 11:52

Hello All-
I stumbled across some different pictures of the 2010 (LMK) 4.5L Duramax (new to me anyway). Thought I would share them...

Happy Holidays.

Is the engine using a BOP (Buick, Olds, Pontiac) transmission bellhousing bolt pattern? It's not a Chevy/GMC V-8 pattern (like the Duramax 6600).

Thanks for the pics,

Jim

Way cool...now there is an engine that would make sense to swap into a rolled caged GM Colorado - then head off to Bonneville for Speed Week...

So much for changing the alternator in your driveway. Looks like you need a hoist...

With all that's going on with GM and the economy does anyone know if this engine is still slated for introduction for the 2010 model year?

Looks like it (at this point anyway). Check out the below link and click on "Truck Engines- 2010": http://media.gm.com/us/powertrain/en...owertrain.html

looks like the fuel filter will be fun to access. Maybe from underneath the vehicle, or through the fender well.

I don't think that means much, because this - LINK - shows it in 2008...

**Rabbler** · 01-12-2009, 18:51

I think the first posted pics are more likely to be close to the actual engine.
That link you posted looks like an artist concept drawing.

The LMK is an interesting animal. Notice the missing exhaust manifolds??

The heads flow backwards compared to a conventional V8!

Supposedly this engine is all GM with no Isuzu influence too.

I wonder which bank is #1 cyl on?

**leolkfrm** · 02-05-2009, 14:24

As of right now the new engine project is on hold!!!!!!!!!

**Showgood1** · 02-05-2009, 20:35

Don't leave us in suspense how do you know? For how long? Good grief we've been waiting for 10 years.

**leolkfrm** · 02-06-2009, 04:45

Tonawanda Engine plant is designated to build it, old machines were pulled out, floor is ready for new, with the economic downturn, and bailout GM put a hold on a lot of things.
Really not a good thought process for turning a business around, but then they always blame the labor force and union for their problems, and the public believes it!!

**More Power** · 02-06-2009, 12:16

Ford shelved their light-duty diesel program as well. They blame the cost imbalance between gas/diesel and the rising fuel economy capability of the newest direct-injected gas engines. I haven't heard from anyone who blames the union for the lack of a light-duty diesel. The leadership at GM/Ford made the decision not to move ahead with their diesel programs.

GM and Ford had the past 8 years to establish a foothold in the light-duty diesel consumer market when 1/2-ton & SUV diesels would have been wildly popular.... They let it slip away...

**trbankii** · 03-10-2009, 08:45

Disappointed to see that - especially as I consider that moving ahead with the program could place them as a market leader in light-duty trucks when they need anything they can get to convince people to put faith in them.

**More Power** · 03-10-2009, 10:57

I agree... GM (and Ford & Dodge) sat on their hands for the past 9 years, even though they had a light-duty diesel in the pipeline. None of them was willing to take the lead and actually introduce one (GM was waiting for Ford to take the lead). In doing so, they all passed up a tremendous opportunity to expand their brand and sell a lot of diesel powered vehicles.

Never say never, but I do not believe GM/Ford/Dodge will ever expand their diesel offerings here in the U.S. I say this because of the current political climate, gas/diesel cost difference, diesel engine option cost premium and the improvement in gasoline technology - primarily direct-injected gas engines and other fuel efficiency technologies that improve gas fuel mileage.

It does expand an opportunity for the Suburban/Duramax conversion market. They're currently selling for about $80K, which begins with a used 2500-series gas powered Suburban.

DMAX is down to a single shift 6-days a week, but they are optimistic for the future. No doubt....

I haven't seen anything lately on the Toyota Tundra diesel. Last I saw was a late 2009 introduction. That could prompt GM and Ford to get off their duffs, but then once again they'll be playing catchup and follow the leader instead of being the leader...

**richp** · 03-10-2009, 16:36

Hi,

I was talking today to the owner of my dealership (Bob Jass Chevrolet in Elburn, IL -- fine outfit). It was his view that GM is shelving the small diesel due to the emissions issues that they see coming down the road.

FWIW.

**ccole** · 03-10-2009, 17:45

I agree with Jim 100% on this. As I am very, very disappointed to hear of this news, I am not surprised.

I believe the future of diesels in US consumer vehicles are continually going to fade away. There are simply too many strikes against the diesels in the U.S. for the market to survive. Such as premium $$ for hardware to meet emissions (DPT, urea, controllers, sensors, etc etc), decreased mpg, higher cost per gallon at pump, increased maintenance costs, politics, EPA, GM financial status, etc etc). Especially when you stand back and look at the engineering gains that have been made in the gasoline powered engines such as: direct injections, HP gains, MPG gains from partial cylinder cut-out, cheaper fuel, etc etc.

I have been a faithful diesel owner since I began driving. Especially partial to GM, but I forecast the 4.5L cancellation is just the beginning of the end for diesel powered consumer vehicles in the US. Keep in mind that the U.S. emission standard "Bin 5/Tier2" is 6 times tougher to meet that Europe’s "Euro 5." Therefore, I forecast the Europe diesel engine market will remain on target, while we fade away here.

Quoting Bob Lutz, GM VP of Global Development "At best, the diesel engine of the future will be tremendously expensive, lower MPG and unsure with emissions can be met for California and Northern States."

Just my $.02

GM delays V-8 diesel production at Tonawanda engine plant

By Matt Glynn
News Business Reporter

General Motors Corp. has made announcements about two products at its Town of Tonawanda engine plant.
The automaker has placed an "indefinite hold" its plan to add a Duramax 4.5-liter V-8 diesel engine in 2010 to its Chevrolet Silverado and GMC Sierra light-duty trucks. It was to be made at the River Road site. The start of the new engine's production had already been delayed this year.
The plant will regain production of a 3.7-liter, Inline 5-cylinder engine that had been transferred from Tonawanda to a plant in Flint, Mich., in 2007. Production of the I-5 is set to resume at the Tonawanda plant this summer.

**MacDR50** · 03-11-2009, 16:28

Much of the ULSD produced in NA meets a less than 10% PPM standard. As a result it can readily be sold in Europe. The production of diesel is increasing while gas production is falling. For the first time in several years diesel prices are below gas in several NA markets. The fall off in offshore demand is a partial factor for this decline.
