GM 3.1 L82

The General Motors 60° V6 engine family is a series of 60° V6 engines which were produced for both longitudinal and transverse applications. All of these engines are 12-valve cam-in block or overhead valve (OHV) engines, except for the LQ1; which uses 24-valves driven by dual overhead cams or (DOHC) instead. These engines vary in displacement between 2.5 and 3.4 liters and have a cast iron block and either cast iron or aluminum heads. Production of these engines began in 1980 and ended in 2005 in the U.S; but continued being produced in China until 2010. This engine family was the basis for the GM High Value engine family. Some refer to these engines as X engines due to first usage in the X-body cars. The L82 ("M-code") was an updated, SFI replacement for the MPFI LH0, produced from 1993 through 1999. It featured a structural oil pan, a stiffer redesigned engine block, sequential fuel injection and revised aluminum heads. Output for the L82 was up 20 hp (15 kW), over the previous Gen II LH0, to 160 hp (119 kW) at 5200 rpm and 185 lb·ft (251 N·m) at 4000 rpm. Compression Ratio for the L82 was 9.5:1 and the bore measured 89 mm (3.5 in) while the stroke was 84 mm (3.3 in) giving it a displacement of 191 CID (3,136 cc). This engine is notable for its cooling system issues which may lead to blown head gaskets and cracked heads.[WIKI]
