[[General Motors Corporation|General Motors]]' [[Opel]] division in Europe designed a compact [[V6]] engine with an odd 54° vee angle. It was an iron block/aluminum head [[DOHC]] design with 4 valves per cylinder. All 54° engines are assembled at [[Ellesmere Port]] in [[England]]. | |||
This engine was used in the American versions of these models as well. The engine was reworked substantially between the 3.0 L L81 and 3.2 L LA3, but the bore centers and deck height were retained. In its 3.0 L form, this engine has a notable history for recalls of all units installed in U.S. Cadillac Cateras due to problems with timing belt tensioner bearing failures, which could cause catatrophic damage to the engine with its interference design. | |||
