3.1L/3100 L82The L82 (\"M-code\") was an updated, SFI version of the MPFI 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 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 if the engine is not maintained properly.Applications:19941999 Buick Century19941996 Buick Regal19941996 Chevrolet Beretta19941996 Chevrolet Corsica19951999 Chevrolet Lumina19971999 Chevrolet Malibu19931997 Oldsmobile Cutlass Supreme (1993 received both LH0 and L82 3.1 L motors)19941996 Oldsmobile Cutlass Ciera19971999 Oldsmobile Cutlass GLS19941999 Pontiac Grand Prix19941998 Pontiac Grand Am19941998 Buick Skylark19941998 Oldsmobile Achieva19951999 Chevrolet Monte Carlo
