Talk:List of GM engines

Oldsmobile-based Diesel engines
The first sentence of the second paragraph is a bit of cause for some concern. It used to read as follows:
 * Due to the fact that they were based off of standard gasoline engine designs...

but now reads:
 * These Diesel engines were designed to fit into the engine bays of gaoline powered automobiles, but despite popular belief, they were not "converted" gasoline engines...

Is it accurate to say this? The reason I ask is that they're essentially beefed-up versions of standard Olds V6/V8 gasoline engine blocks, albeit with big-block sized main journals. While there are some differences, they're basically modified versions of their gasoline counterparts, aren't they? I'm inclined to change it back, but looking for arguments against doing so.--King V 18:41, 23 May 2006 (UTC)
 * I'm not really convinced that any of that discussion actually belongs within this article - I think it's better served being included with the Oldsmobile V8 engine article and its Diesel section. However, what's there now needs a lot of sourcing for its claims first before that would even make sense. I just spent a good chunk of time adding to the list (basically rounding out GM's impressive engineering history and cleaning up a LOT of redundant redundancies under each engine family) - and after all that, the big honking "Diesel" section looks somewhat out of place. I already moved a paragraph into the Chevrolet Corvair engine article (which still needs sourcing too); I'm thinking of doing the same in this case. Duncan1800 (talk) 11:47, 19 May 2008 (UTC)

I'm a little concerned with the bias shown in the olds diesel section. The author mentions poor failures from design, then proceeds to list failures from maintenance, improper rebuilds, misuse of one use parts, etc, etc, as those failures from design. One of the most common mistakes non-engineering people commit is to use something outside of its designed use, or fail to maintain it within its designed maintenance schedule, then, when it fails, blame it on the design. Even the best engine in the world needs timely oil changes. Like most people on the internet, the author's credentials are called into question. —Preceding unsigned comment added by 74.137.221.66 (talk) 15:41, 20 March 2010 (UTC)

I think the entire Section 8 (Automotive diesel engines) is superfluous especially considering this article is a list. It seems silly to have conflicting and debatabley biased diatribe about the Olds diesel and its impact on North American diesel perceptions; there is already a list of GM diesel engines in section 5 and this article is not really meant to be a source of info about the motors, it is merely a list linking said motors to their respective articles. Would anyone be opposed to deleting section 8? DieselDork (talk) 14:56, 11 October 2012 (UTC)

1917 Chevrolet V8, 1932 Oakland & Pontiac V8
Please add any information on these little-known engines.
 * There's a lot of other "classic" GM engines, including the Copper-Cooled Chevrolet and the earliest Oldsmobile V8 (from 1916). I'm also looking at adding GM's industrial and diesel designs (from Electro-Motive, Detroit Diesel, etc.) into this list. The name of the company is General Motors, after all - best to include the full depth and breadth. Duncan1800 (talk) 12:10, 18 May 2008 (UTC)

2.9L V6 diesel in European Cadillac CTS
I spotted this article from Autoblog about a new 2.9L V6 diesel for the Cadillac CTS in Europe http://www.autoblog.com/2007/03/06/geneva-motor-show-cadillac-unveils-new-2-9l-v6-diesel-for-cts -user Sd-100

I have a question: My 1980 GMC truck had a blown V6 motor in it when I bought. I have a V8 350 motor on hand. I know it will fit, but here is the question.. It has a two gas tanks, which required a 3 outlet for the the V8, but the V6 only has a 2 outlet. What is the third outlet for on the V8..... —Preceding unsigned comment added by 66.174.79.238 (talk) 16:22, 11 September 2007 (UTC)

Major expansion mostly complete - additional rant follows!
I've reworked this list pretty extensively, adding in a lot of missing engines (many of which will need pages created for them) and even throwing in some of GM's heavy-duty production to provide historical perspective. I know I'm still missing some things - early Vauxhall engines come to mind (damn it!) and there may be other regional production from South America, Asia, etc. that I'm not aware of. The help of Wikipedians from elsewhere in the world (outside the US, that is) would be greatly appreciated, especially in pinning down dates and specifics for Opel/Vauxhall production and refining the data for other "world" engines.

The list has been organized mainly in a historical way, tracing GM's engine development through the years - I feel this is more instructive (and interesting) than grouping things by division; others may disagree, and I would welcome additional input. I'm also somewhat hamstrung by the way individual engine pages are currently organized - instead of starting with a semi-DAB page like "Cadillac V8 engine" and expanding from there (into, say, separate pages for L-head, OHV, aluminum, and Northstar V8s), everything is currently mixed into confusing jumbles on single pages. I understand how to get through all these pages now, but that's only after months of learning the "tricks" needed to do so. Most of what exists seems incomplete as well, at least compared to my own references.

I'm also of the opinion that sprawlingly huge pages like "GM Vortec engine" should be nothing more than DAB pages, giving links only to the various engine families (Atlas, small-block, LS, etc.) under that name and sorting things out within those pages instead. On that note, if Ford's Duratec brand has a page, why doesn't GM's equally notable EcoTec brand?

At some point, I may decide to rework this list into a series of tables instead, but that's down the road. I'd also like to work up a comprehensive, cross-referenced list of RPO engine codes (don't laugh - I've already tortured myself with the similarly daunting list of NASCAR race tracks, so RPO codes shouldn't be much more painful). For now, though, I think this gives a good base from which to further refine and Wikipedia's coverage of General Motors and its engineering achievements. Duncan1800 (talk) 13:28, 20 May 2008 (UTC)

I have just added archive links to 1 one external link on List of GM engines. Please take a moment to review my edit. If necessary, add after the link to keep me from modifying it. Alternatively, you can add to keep me off the page altogether. I made the following changes:
 * Added archive https://web.archive.org/20120814143041/http://www.oaklandowners.com:80/pages/History_McCargar.html to http://www.oaklandowners.com/pages/History_McCargar.html

When you have finished reviewing my changes, please set the checked parameter below to true to let others know.

Cheers. —cyberbot II  Talk to my owner :Online 01:48, 9 September 2015 (UTC)

poor list design
This article has a major problem in it's layout (probably because it was started as an automotive article). There are sections for "Locomotive", "Marine", and "Industrial", however the same GM engine families were used across these categories - the 567 engine, for example, was used in locomotives, tugboats and ferries, and stationary generator and pump applications; the Series 71 engine was used in trucks and buses, fishing boats, and stationary applications - so trying to divide these will result in repetition in each category. I'm tempted to just lump them all together under "Heavy Duty" engines.
