V-shaped engines, including the LG8, have a tendency to develop oil leaks due to the complex design and multiple gaskets required to seal the engine.
Intake manifold gasket failure
The intake manifold gaskets on the 2002 Buick Century with the LG8 engine are prone to failure, leading to coolant leaks and potential engine overheating.
Ignition coil issues
The 6-cylinder LG8 engine may experience problems with ignition coils, causing misfires, rough idling, and poor engine performance.
Coolant leaks
The coolant passages in the V-shaped LG8 engine can develop leaks, especially around the intake manifold and head gaskets.
Timing chain wear
Over time, the timing chain in the LG8 engine can wear out, which may lead to improper engine timing and a decrease in performance.
Egr valve problems
The Exhaust Gas Recirculation (EGR) valve can become clogged or fail, leading to increased emissions and poor engine performance.
Crankshaft position sensor failure
The crankshaft position sensor on the LG8 engine can fail, causing the engine to stall, have trouble starting, or run inconsistently.
