I applaud whoever wrote this entry, however I noticed some serious mistakes which I will attempt fix. Anyone else attempting to edit this should probably start thier research at 60degreev6.com, domesticcrew.com, or V6Z24.com. I have found that those sites contain the most useful information regarding the 660 (as it's known in enthusiast circles).

Edit: After rereading the original entry, the mistakes were worse than I thought.

Much of the information is presented in a confusing manner, some of it is just very incorrect.

The 60°V6 was designed from scratch. It shares nothing in common with the 90°V6 except the number of cylinders. It is not in anyway based on the 90° V6, nor could any it be considered the 660s predecessor.

This would be my first wiki edit, so I appologize if I make any formatting errors, please bear with me. My main focus though is to correct the misinformation.

"The General Motors 60° V6 family of engines engines began with the 1978 Buick 3.2 L V6" Since when? Nothing I've ever read suggests it, & my issues of CC, HR, & C&D from when the 2.8 was intro say it was a brand-new design. In fact, as I recall, the Buick was a 90°V6... Can somebody confirm? Otherwise, I'm changing it. Trekphiler 08:18, 29 December 2005 (UTC)[reply]

You're absolutely right on this one. Nobody's changed it yet, though, so I changed it to 1980, Chevrolet, and 2.8L. --King V 14:33, 10 March 2006 (UTC)[reply]

"no interchangeable parts between this DOHC engine and any other members of the 60° family"? Really? The 3.4/12v slugs, the 3.1's crank, the ignition, all were designed new & N fit? Fat chance. Confirm, or I'm changing that, too. Trekphiler 08:22, 29 December 2005 (UTC)[reply]

Trekphiler, the 3.1 crank casting is used but the throws are further machined for the DOHC. The 3.4/12V pistons are completely different. Electronics are identical. Internal stuff, no. The rods and main bearing caps are really the only things that didn't change. Series8217 —Preceding unsigned comment added by 131.179.80.43 (talk) 19:21, 29 February 2008 (UTC)[reply]

OK, dating the 3.1's wrong, too. The aluminum head & front cover were '86 ('87 model year), the 3.1 the next year, as I recall (without sources in front of me), not '90 as the article suggests (unless it meant "next year" to mean '88, which is neither clear from context, nor correct...). Can somebody confirm & correct? Trekphiler 08:29, 29 December 2005 (UTC) There seem to be a lot wrong on the dates on the LG8 It says the earliest applications where in 1999, when I know that a 1995 Grand Prix has a 3100 Engine in it (or a 3.4) and so dose the Cutlass Supreme.[reply]

No need for speed

I deleted the 0-60 & 1/4 times as meaningless drivel. Obviously, the original poster had no conception of testing: unless the results were in the same car, by the same driver, at the same place, on the same day, or with suitable correction factors (which I suspect yon poster never heard of, let alone took account of), the results are about as valuable as a $3 bill.

The '78-79 3.2 litre V-6 was a debored 90 degree Buick engine, which was discontinued because it was seriously underpowered and consequently unpopular with buyers. It has the same crank as the 3.8/231 and is in no way connected with the later 60 degree V-6. I agree that 0-60 and quarter mile times are irrelevant for this article. (Jonathan Versen 08:21, 12 February 2006 (UTC))[reply]

Agreed. The references to Buick V6s and the 3.2 litre from 1978-1979 more appropriately belong on the GM_3800_engine page, and I make mention of it on that entry's discussion page. This page should probably be called something else, since the 3200 designation never existed. (King_V)

Whoops, rather, the redirection should simply be removed (I didn't realize that GM_3200_engine redirected to GM_60-Degree_V6_engine. --King V 23:16, 9 March 2006 (UTC)[reply]

L body 2.8 engines?

from 1987 to 1990, the corsica and beretta used a 2.8, but which one was it? and where does it belong in this article?

87-on 2.8 should be Gen II. Toastysoul 06:27, 13 April 2007 (UTC)[reply]

F body 3.4l engines

I added a bit to the 3.4l section. it mentioned there were two variants and went on to describe three, so I cleaned that up a bit. I'll add more to the L32 section eventually. (I have one myself :) ) -notsonic

I've got a question..

I've got a question about the 3.1 V6 used in the Lumina APV/Pontiac Trans Sport/Olds Silouette. I was told on one internet forum that this particular version of the 3.1 in actuality has more in common with the first generation transverse 2.8 V6 than it does with the Generation II V6's. I was told the 3.1 in the U vans has iron heads like the old 2.8's, therefor they don't have the problem with headgaskets that the Gen II V6's had. Can anyone confirm that? I'm looking at buying a 94 Lumina APV with the 3.1 and I'm just checking to make sure these engines weren't the ones with the headgasket problems. 156.34.196.76 21:06, 21 January 2007 (UTC)[reply]

You are correct. The minivans used the Gen I engine until some time in the mid 90's (probably 96 or 97 when the new model was introduced). I would update the entry, but I'm not sure exactly when they actually stopped using it. Actually now that I look at it, I believe there is some other incorrect info about which cars had the Gen I cast iron vs Gen II aluminum heads, but I'm going to have to dig for more info to be sure.Sketch242 19:07, 1 February 2007 (UTC)[reply]

Cadillac Cimarron

The Cadillac Cimarron (J body) also used the 2.8L V6 beginning in 1985, getting the Gen II as standard equipment in 1987 along with the rest of the cars that used it. The 1987 and 1988 Cimarron were unique in that they did NOT move to the redesigned J platform. 'Course nobody would know that from this article...

Current production

The original size block 60 degree V6 is still in production, in two different forms. You can walk into any GM dealer's parts department and order the 3.4L HT. That's the complete engine minus intake manifold and oilpan. It's intended for trucks and rear-drive cars that originally came with a 2.8L or 2.9L carbureted engine. (It CAN be used with Mass Air Flow EFI but CARB, EPA and the DOT won't allow GM to market it for such applications.) It does NOT have the engine and starter mounts for transverse applications.

The other one is an aluminum block (weighs only 20 pounds bare!) with engine and starter mount points for longitudal or transverse applications.

3.1 problem

In the early 90's, there is a problem with many of the 3.1 engines where the camshaft timing sprocket bolts weren't torqued enough and they'll work loose. The result is a banging noise as the sprocket comes loose and eventually a scraping and squeaking sound as the bolt heads hit the inside of the timing cover. The books I have specify a mere 15 inch-pounds torque on those bolts! 15 FOOT-pounds is more like what the torque should be. I had this happen in a 1991 Oldsmobile Silhouette van and I've seen the same problem in others of those plastic vans as well as in some GM cars of the same years. Far as I know, GM has never issued a recall for the under-torqued cam sprocket bolts. —The preceding unsigned comment was added by Bizzybody (talk • contribs) 02:26, 13 April 2007 (UTC).[reply]

LB6

Someone should look carefully at the LB6. Beretta GT was added here through 90, but my understanding is that Berettas moved to Gen II design with the other platforms in 87. I added in the Cavalier for 86-87. The Gen II's were actually transitioned into 87 models mid year. Many 87 vehicles left the factory with Gen I iron head engines (i.e LB6s).

L-Body 91-96 V6 Vin M engines

Hi,

Just noting that the 1994-1996 Chevy Corsica had the Gen-3 L82, SFI engine (as per 1995 GM L-Body Service Manual), not the Gen-2 MPFI one. Its V6 engines were the same as the Beretta's for 91-96.
