Most engines on the market today are exceptionally reliable provided that regular maintenance is attended to, so I'm not sure if reliability is really dependent upon the manufacturer than it is on the end user.

I have to agree with TP... I like the GMC 305 V6.
the biggest of the 60's GMC v6 was a 478ci monster!
Hmmm... An ECU become self-aware and then reflashed at least one too many times?

Best V6 ever... the new Infiniti G37 Coupe with it's 3.7 liter DOHC, making 330 horsepower and almost 30mpg on the freeway! Nissan power...
Nissan V6 end of story. Even the Germans gave them an award

Here is a web page that has all the big block GM V6 engines, including the 305, 401, and 478 cid.
I am a huge fan of the I-6's in BMW. They are just plain great motors from the 2.3L to 3.5L in various gyration from mid 80's - 2004.
The VW VR6 placed into a Corrado was a nice combination too.
3800 is decent but the cars I don't like nor the slush box they are typically coupled to.

Buick Grand National/T-Type turbo 3.8L V6
Looks like the GM 3.8 V6 takes the cake. A lot of the engines people are naming haven't even been around for 10 years... where's the reliability test in that? Hasn't the 3.8 been around for 20 years now, since the 87 Buick GN? Or was the GN out a little sooner?
Somehow, I've managed to break two of the GM 3.8L engines. Both suffered timing failures.
Both jumped timing. One still ran, the other didn't.
The first was a 1975 Buick Century with the V6, the other was an 87 LeSabre.
So the engine has been around quite a while.

The engine in the Grand national is a wonderful engine.what makes it low tech?
ohc engines cost less to make.Quote:

LOL, you had better ask GM that question. Many reports say that 2008 will be the end of the road for the old warhorse. It is being replaced by 3.5 and 3.9 liter versions of the 60 degree V-6 engine family. For 2007 it is only used in certain of the Buick LaCrosse and Lucerne models.

The anachronistic 3.8l 90 degree V-6 is finally being put to rest. The new engines are interesting in that they incorporate variable valve timing into a pushrod engine design and use the inherently balanced 60 degree cylinder bank relationship. GM is probably the last company in the world still tweaking pushrod engine designs for cars. Everyone else has moved on to overhead cams. Even GM makes it's premium engines with overhead cams and saves the pushrod architecture for the certain of the cheap seats.

I'll go with the Vulcan V6. Not very brawny ..but tough. Plenty good for its appointed task and asking little in return
I don't really like the Mitsubishi 3.0 V6. It's got no good reason for being as functional as it is in all the versions that it was offered in. Turbo, twin turbo, SOHC, DOHC. Mild to amazing. They may have annoyed many with being either foggers or HLA tickers ..but I never really heard of too many blowing apart or being inherently problem prone.

Nissans VG, VQ variants, by far... most durable also.
Ford's Vulkan v6 - also very durable.
Toyota's and Hondas newer V6's are good also, but not sure how proven they are.
Didn't GM's 3.8 motors have lower intake gasket roblems, just like their 3.1's have?? If so, I don't see how they could be voted as "best". I'm also tired of hearing about jeeps head cracking 4.0L sludge monster I-6.(flame suit on)

As it happens, we've owned (or own) cars with each of these engines (1990 Merc Sable wagon, 2004 G35 sedan, 2007 Avalon). The Vulcan performed flawlessly for almost 11 years and ~105k miles on 2-3 M1 oil changes per year. The VQ deserves all the praise it gets here and everywhere else. But I'm going on a limb and, as I noted above, voting for the Toyota 2GR-FE 3.5L. Time has yet to tell if it will prove as durable as the VQ, but I prefer its feel, response, etc. This is a very nice engine. BTW, in the Avalon, it comes with a very effective 5-spd auto, unlike the unpopular 6-spd found in the V-6 Camry.
Got to put in 1 more shout out for the Ford 4.9L inline 6. I owned one for a few years. That engine was a work horse and would purr like a kitten as long as you could seal up every vacuum leak. Had 220k when I sold it, and it could still pull a house without breaking a sweat.
