The '''[[General Motors Corporation|General Motors]] 60° V6''' family of engines began with the 1980 [[Chevrolet]] 2.8&nbsp;L [[V6]] and continues to be produced today (if one doesn't count a larger block casting with larger bore center and new cylinder heads). Its use in the [[GM X platform|X-body]] cars leads some to refer to it as the '''X engine'''.


It is a 60° vee block with [[pushrod]] heads, except for a single [[DOHC]] member, the [[#LQ1|LQ1]]. This engine family continues with the new [[GM High Value engine]].
This was the first [[Overhead camshaft|overhead cam]] (OHC) engine from [[Opel]], featuring milestone technologies like:
*Aluminum head.
*Cross flow design
*Multi point fuel injection
*Electronic ignition/fuel injection.
*Over Head Cam


==Generation I==
This was "the" beginning of all the later Opel petrol engines.
The first generation of GM 60° V6 engines featured an iron block and heads with inline valves. This generation started in 1980 and versions were produced through 1996. Two different blocks were developed:
This was the first time the cast iron block found in most newer 2 liter Opel engines was featured.
* A [[transverse engine]] family for [[front-wheel drive]]
* A [[longitudinal engine]] family for [[rear-wheel drive]]


===Transverse===
{| class="wikitable"
The [[transverse engine]]s began the 60° family in 1980. Like the rest of the Generation I engines, they were updated in 1985 with larger main journals for durability, along with [[multi-point fuel injection]] or E2SE carb and [[OBD I]]. Production of the Generation I transverse engines ended in 1986.

===Longitudinal===
The [[longitudinal engine|longitudinal]] versions were quite different from the transverse engines on which they were based. This group appeared in 1982 with the [[#LC1|LC1]] and [[#LR2|LR2]] and never added the aluminum heads of the [[#Generation II|Generation II]] engines.
 
Like the rest of the family, larger journals appeared in 1985, along with [[MPFI]] for the [[GM F platform|F-body]] [[#LB8|LB8]] version. [[Fuel injection#Throttle-body injection|TBI]] was added for the truck version in 1986.
 
A 3.1&nbsp;L version was added in 1990 with an 8&nbsp;mm longer stroke, and a 3.4&nbsp;L appeared for 1993 with a 92&nbsp;mm bore and [[SFI]]. Production of the 2.8&nbsp;L and 3.1&nbsp;L ([[Isuzu]]) engines ended in 1994. Production ended for all longitudinal 60° V6s in 1996, though GM's performance parts division continued production of a related crate engine after 1999.
 
====LC1====
The longitudinal '''LC1''' was produced from 1982 to 1984. It was a 2-barrel High Output ("1-code") version for the [[GM F platform|F-body]] cars. Output was 102&nbsp;hp (76&nbsp;kW) and 145&nbsp;ft·lbf (197&nbsp;N·m). It was replaced by the [[#LB8|LB8]] for 1985.
 
Applications:
* 1982-1984 [[Chevrolet Camaro]]
* 1982-1984 [[Pontiac Firebird]]
 
====LR2====
The longitudinal '''LR2''' was a truck version ("B-code") produced from 1982 to 1990. It used a 2-barrel [[carburetor]] and produced 115&nbsp;hp (86&nbsp;kW) and 150&nbsp;ft·lbf (203&nbsp;N·m).
 
Applications:
* 1982-1986 [[Chevrolet S-10]]/[[Chevrolet S-10 Blazer]]
* 1982-1986 [[GMC S-15]]/[[GMC S-15 Jimmy]]
* 1984-1986 [[Jeep Cherokee#XJ (1984–1996)|Jeep Cherokee]]
* 1986 [[Jeep Comanche]]
 
====LL1====
The longitudinal '''LL1''' was a high-output version of the [[#LC1|LC1]] produced in 1983 and 1984. It was an optional ("L-code") engine on the Pontiac Firebird with 125&nbsp;hp (93&nbsp;kW).
 
Applications:
* 1983-1984 [[Pontiac Firebird]]
 
====LB8====
The '''LB8''' ("S-code") replaced the [[#LC1|LC1]] in 1985 and was produced until 1989. It used multi-port [[fuel injection]] and was made for longitudinal mounting. Output was 135&nbsp;hp (101&nbsp;kW) and 165&nbsp;ft·lbf (224&nbsp;N·m).
 
Applications:
* 1985-1990 [[Chevrolet Camaro]]
* 1985-1989 [[Pontiac Firebird]]
 
====LL2====
The carbureted '''LL2''' ("R-code") was produced from 1982 to 1983. Another LL2 ("R-code") with [[throttle body]] [[fuel injection]] was produced from 1986 to 1993.
 
Applications:
* 1986-1993 [[Chevrolet S-10]]/[[Chevrolet S-10 Blazer]]
* 1986-1993 [[GMC S-15]]/[[GMC S-15 Jimmy]]
* 1989-1991 [[Isuzu Trooper]]
 
==Generation II==
The second generation, still 2.8 liters, was introduced in 1987. It used aluminum heads with splayed valves and an aluminum front cover. It was produced exclusively for transverse, front-wheel drive use.
 
The next year, Chevrolet introduced a full-production long-stroke 3.1&nbsp;L (3136&nbsp;cc, 191&nbsp;CID) version, thanks to an 89&nbsp;mm bore and 84&nbsp;mm stroke. It was produced simultaneously with the 2.8L in various compact & midsized vehicles until 1990 when the 2.8L was dropped.  [[MPFI]] was added to both, and a full-production turbo version was available on the 3.1L. An even higher displacement [[DOHC]] 3.4&nbsp;L [[#LQ1|LQ1]] was also developed and, eventually, the new [[GM High Value engine]] family followed. Production of Generation II engines ended in 1994 after the introduction of the [[#Generation III|Generation III]] in 1993.
 
The 2.8&nbsp;L 60° V6 was used in the following vehicles:
* 1988-1989 [[Buick Regal]]
* 1987-1989 [[Chevrolet Beretta]]
* 1987-1989 [[Chevrolet Cavalier]] Z24
* 1987-1989 [[Chevrolet Corsica]]

* 1990-2003 [[Pontiac Grand Prix]]
* 1990-1994 [[Pontiac Sunbird]]
* 1990-1995 [[Pontiac Trans Sport]]
 
===LG6===
The '''LG6''' ("D-code") was produced from 1990 to 1996. It used [[fuel injection#TBI|throttle-body injection]] and iron heads. It produced 120 hp.
 
Applications:
*1990-1995 [[Chevrolet Lumina APV]]
*1990-1995 [[Oldsmobile Silhouette]]
*1990-1995 [[Pontiac Trans Sport]]
 
===LH0===
The '''LH0''' ("T-code") was introduced in 1988 on the Pontiac 6000 STE AWD. It featured a more exotic (for the time) [[fuel injection#MFI|multi-port fuel injection]]. While not known for its high RPM power, the LH0 has strong low- and mid-range torque.  The 3.1 L engine has retained an excellent reputation for reliability.  It was produced until 1996 and was exported in some models. This engine produced 135hp and 180lb/ft of torque from 1988-1989, then upgraded to 140hp and 185lb/ft of torque.
 
Uses:
*1988-1991 [[Pontiac 6000]] STE & LE
*1990 [[Chevrolet Celebrity]]
*mid 1989-1993 [[Pontiac Grand Prix]]
*mid 1989-mid 1993 [[Oldsmobile Cutlass Supreme]]
*mid 1989-1993 [[Buick Regal]]
*1990-1992 [[Chevrolet Beretta]] GT
*1990-1994 [[Chevrolet Lumina]]
*1990-1994 [[Chevrolet Cavalier]]
*1991-1994 [[Pontiac Sunbird]]
 
===LG5===
The '''LG5''' ("V-code") was a special 3.1&nbsp;L [[turbocharged]] engine produced with [[McLaren]] for just two years, 1989 and 1990. It featured the same multi-port fuel injection intake manifolds and throttle body as the '''LH0''', but cranked out {{Convert|205|hp|kW|0|abbr=on}} at 5200&nbsp;rpm and {{auto ftlbf|225}} of torque at 2100&nbsp;rpm.
Approximately 3,700 engines were produced each year. This engine had a block with more nickel content and hardened internals.
 
This engine is notable, along with other GM turbo engines of the era (such as that found in the Typhoon/Syclone), for the ease with which significant performance gains can be realized with relatively pedestrian modifications.
 
Applications:
*1989-1990 [[Pontiac Grand Prix]] ''Turbo''
*1990 [[Pontiac Grand Prix STE]] ''Turbo''
 
==Generation III==
The third generation of the 60° engine was introduced in the 1993 [[Oldsmobile Cutlass Supreme]]. It was still an iron block/aluminum head engine, but the head was redesigned for better air flow.
 
From the mid-1990s to 2003, some versions (the plastic intake manifold version) of this engine are involved in intake manifold gasket defects which caused coolant leakage often leading to engine failure.  A series of [[class action]] lawsuits, implicating deterioration of the [[nylon]]/[[silicone]] material of the gasket & the heat warping of the plastic intake manifold upon exposure to [[Antifreeze#Organic acid technology|Dexcool antifreeze]], are pending on this issue.  Tell-tale signs of such eventual related damage are a white foam that appears on the inside of the oil filler cap and the gradually increasing loss of antifreeze coolant (due to seepage into the intake passages which will lead to engine lock up failure in such cases).  External seepage is also found near the
valley edge of the lower intake manifold.
 
===3.1L/3100===
====L82====
The '''L82''' ("M-code") was an updated, [[fuel injection#Multi-point fuel injection|SFI]] version of the [[fuel injection#Multi-point fuel injection|MPFI]] [[#LH0|LH0]], produced from 1993 through 1999. It featured a structural oil pan, a stiffer redesigned engine block, and sequential [[fuel injection]]. Output for this version was up 20&nbsp;hp to 160&nbsp;hp (up 15&nbsp;kW to 118&nbsp;kW) at 5200 rpm and 185&nbsp;ft·lbf (250&nbsp;N·m) at 4000 rpm. Compression Ratio for the L82 was 9.5:1 and the bore measured {{convert|89|mm|in|abbr=on}} while the stroke was {{convert|84|mm|in|abbr=on}} giving it a displacement of 191&nbsp;CID (3,136&nbsp;cc).
 
Applications:
* 1997-1999 [[Buick Century]]
* 1994-1996 [[Buick Regal]]
* 1994-1996 [[Chevrolet Beretta]]
* 1994-1996 [[Chevrolet Corsica]]
* 1994-1999 [[Chevrolet Lumina]]
* 1997-1999 [[Chevrolet Malibu]]
* 1993-1997 [[Oldsmobile Cutlass Supreme]] (1993 received both [[#LH0|LH0]] and L82 3.1 L motors)
* 1994-1999 [[Pontiac Grand Prix]]
* 1994-1998 [[Pontiac Grand Am]]
* 1994-1998 [[Buick Skylark]]
* 1994-1998 [[Oldsmobile Achieva]]
* 1995-1999 [[Chevrolet Monte Carlo]]
 
====LG8====
The '''LG8''' ("J-code") was a modern version of the 3.1&nbsp;L engine that displaced 191&nbsp;cubic inches (3,136&nbsp;cc)<ref>http://media.gm.com/division/2003_prodinfo/03_powertrain/03_car_engine/index.html</ref>, produced since model year 2000{{Fact|date=February 2007}}. It still had an iron block and 2-valve pushrod aluminum heads but now had full [[fuel injection|sequential port fuel injection]]. The LG8 also featured a new [[intake manifold]] and numerous changes to improve parts sharing with the offshoot [[GM High Value engine]] family. Emissions were improved with air injection for [[LEV]] status. Power was 170&nbsp;hp-175&nbsp;hp (127&nbsp;kW to 131&nbsp;kW) and torque was 190&nbsp;ft·lbf–195&nbsp;ft·lbf (258&nbsp;N·m to 264&nbsp;N·m). The LG8 was built in [[Ramos Arizpe]], [[Coahuila]], [[Mexico]] and [[Tonawanda, New York]].
 
Applications:
* 2000-2003 [[Pontiac Grand Prix]] SE
* 2000-2005 [[Buick Century]]
* 2000-2003 [[Chevrolet Malibu]]
* 2000-2001 [[Chevrolet Lumina]]
* 2002 [[Chevrolet Lumina]] (Fleet Vehicle)
 
===3.4L/3400===
GM produced three 3.4&nbsp;L (204&nbsp;CID/3,350 cc) variants of the 60° block: The [[#L32|L32]], a normal large-bore [[Overhead valve|OHV]] descendant of the 3.1&nbsp;L (not to be confused with the 90° Series III L32 supercharged), the [[#LA1|LA1]], and a performance-oriented [[DOHC]] version, the [[#LQ1|LQ1]].
 
====L32====
The power rating of the 3.4&nbsp;L '''L32''' ("S-code") used in the Camaro and Firebird was 160&nbsp;hp (120&nbsp;kW ) @ 4,600&nbsp;rpm and 200 ft·lbf (270 Nm) torque @ 3600&nbsp;rpm.
 
Applications:
* 1993-1995 [[Chevrolet Camaro]]
* 1993-1995 [[Pontiac Firebird]]
 
====LQ1====
The '''LQ1''' (also called the '''Twin Dual Cam''' or '''TDC''') was a 3.4&nbsp;L [[DOHC]] V6 motor ("X-code") based on the  aluminum headed second generation of GM's 60° engine line, sharing a similar block with its [[pushrod]] cousins, the 3.1&nbsp;L [[#LH0|LH0]] [[V6]] and the then recently retired 2.8&nbsp;L [[#LB6|LB6]] [[V6]]. The motor was built only for front wheel drive applications, and was featured exclusively in the first generation of [[GM W platform|GM's W-body platform]].
 
It was built from 1991 to 1997. From 1991 to 1993, it used tuned [[fuel injection#(MFI)|multi-port fuel injection]], made 200-210&nbsp;HP (150-160 kW) @ 5200&nbsp;RPM and 215 ft·lbf (290&nbsp;Nm) of torque @ 4000&nbsp;RPM. From 1994 to 1997, it used sequential port fuel injection, making 215&nbsp;hp (160 kW) @ 5200&nbsp;rpm and 225&nbsp;ft·lbf (300&nbsp;Nm) of torque @ 4000&nbsp;rpm. It had four large valves per cylinder. The 3.4&nbsp;L engine used a cogged belt to drive the four overhead camshafts. Adapting a [[pushrod]] block for the LQ1's overhead cams was difficult, and the 60° angle made this a very tall engine, but power output was impressive. 
 
Bore was increased to 92&nbsp;mm, but the 3.1&nbsp;L engine's 84&nbsp;mm stroke was retained. There are only a few interchangeable parts between this DOHC engine and other members of the 60° family, namely the connecting rods and crankshaft.
 
The heads and intake manifolds were redesigned for the 1996 model year, incorporating a larger throttle body and plenum area, slightly shorter intake runners, cloverleaf combustion chambers, and larger "pill"-shaped exhaust ports. Camshafts and cam timing were also revised for the new, higher RPM powerband.
 
Optional from 1991 to 1993 was a [[Getrag 284]] 5-speed manual [[transaxle]], which was also exclusive to the [[GM W platform]] and was available only with the LQ1. The electronically controlled [[Hydramatic]] [[GM 4T60-E transmission|4T60-E]] 4-speed automatic [[transaxle]] was the alternative, used during the entire production run.
 
Applications:
* 1991-1994 [[Chevrolet Lumina]] ''Z34'' and the Euro ''3.4'' sedan
* 1991-1995 [[Oldsmobile Cutlass Supreme]]
* 1991-1996 [[Pontiac Grand Prix]]
* 1995-1997 [[Chevrolet Monte Carlo]] ''Z34''
* 1995-1997 [[Chevrolet Lumina]] ''LS''
* 1997 [[Chevrolet Lumina]] ''LTZ''
 
====LA1====
 
The '''LA1 3400''' ("E-code") was a bored-out version of the 3100. It retained the [[Overhead valve|OHV]] layout of the previous engine, and was first utilized on the 1996 [[List of GM platforms|U platform]] minivans and appeared in a car for the first time in the 1999 [[Pontiac Grand Am]] and [[Oldsmobile Alero]]. A {{Auto mm|92|1}} bore with the same {{auto mm|84}} stroke brought the displacement to 3.4&nbsp;L ({{convert|3350|cc|CID|abbr=on|disp=s}}). Like the LG8, the LA1 featured numerous common parts with the similar [[GM High Value engine]] family. Power was up to 170&nbsp;hp-185&nbsp;hp (127&nbsp;kW to 138&nbsp;kW) and torque was {{convert|210|ft.lbf|N.m|abbr=on}}. The 3.4 L engine is known to have intake manifold gasket problems causing engine damage if the owner of the car neglects to check or change the gaskets (if necessary). Many aftermarket companies have released gaskets that correct this problem for good.
It is used in the following:
* 1996 [[Chevrolet Lumina APV]]/[[Pontiac Trans Sport]]/[[Oldsmobile Silhouette]]
* 1997-2004 [[Chevrolet Venture]]/[[Pontiac Montana]]/[[Pontiac Trans Sport]]/[[Oldsmobile Silhouette]]
* 1999-2004 [[Oldsmobile Alero]] GL/GLS
* 1999-2005 [[Pontiac Grand Am]] SE/GT
* 2001-2005 [[Pontiac Aztek]]/[[Buick Rendezvous]]
* 2000-2005 [[Chevrolet Impala]]
* 2000-2005 [[Chevrolet Monte Carlo]]
 
===China===
Production of the 60° family began in [[China]] with the success of the [[Buick]] marque there. Importation of Chinese-built engines to the United States began in 2004 with the [[#LNJ|LNJ]] found in the [[Chevrolet Equinox]].
 
====LB8====
The '''LB8''' is [[General Motors Corporation|General Motors]]' base [[V6]] in [[China]]. It is a derivative of the [[#LG8|LG8]] with the same 89&nbsp;mm bore and a shorter 66.7&nbsp;mm stroke for 2.5&nbsp;L (2490&nbsp;cc). It is still an iron block with pushrods and an aluminum 2-valve head. Power is 145&nbsp;hp (108&nbsp;kW) and 155&nbsp;ft·lbf (210&nbsp;N·m). It is built by [[Shanghai GM]] in [[Shanghai, China]].
 
Applications:
* [[Buick Century|Buick GL/GLX (China)]]
 
====LW9====
The '''LW9''' is a larger version of the [[#LB8|LB8]] with an 80&nbsp;mm stroke for 3.0&nbsp;L (2986&nbsp;cc). Power is 170&nbsp;hp (127&nbsp;kW) and torque is 185&nbsp;ft·lbf (251&nbsp;N·m).
 
Applications:
* [[Buick Century|Buick GL/GLX/GL8 (China)]]
* [[Buick LaCrosse]]
 
====LNJ====
The 3.4&nbsp;L '''LNJ''' is a 204-cubic-inch (3,350 cc) modified version of the normal 3400 engine. It includes a modified [[intake manifold]], oil pan, engine cover, and fuel system as well as [[electronic throttle control]]. It is built in China and imported to Canada for use in the [[Chevrolet Equinox]] and [[Pontiac Torrent]].  The LNJ makes {{Convert|185|hp|kW|0|abbr=on}} and {{auto ftlbf|210}}.<ref>http://media.gm.com/us/pontiac/en/product_services/r_cars/r_c_torrent/08index.html</ref>

The 20NE is a fuel-injected, four cylinder engine developed by General Motors.

This was the first overhead cam (OHC) engine from Opel, featuring milestone technologies like:

  • Aluminum head.
  • Cross flow design
  • Multi point fuel injection
