Problems:

Oil leaks

V-shaped engines, including the L67, are prone to oil leaks due to the complexity of their design and the number of gaskets and seals that can wear out.

Supercharger issues

The supercharger on the L67 can develop problems such as bearing noise, reduced efficiency, and eventually failure if not properly maintained.

Intake manifold gasket failure

The intake manifold gaskets on the L67 are known to fail, leading to coolant leaks and potential engine overheating.

Ignition coil failure

The L67 often experiences issues with ignition coils, which can cause misfires, rough idling, and reduced performance.

Coolant leaks

Due to the supercharged configuration, there are more potential points for coolant leaks, especially from the lower intake manifold gasket and supercharger assembly.

Harmonic balancer failure

The harmonic balancer in the L67 can deteriorate over time, leading to vibrations and potential engine damage if not replaced.

Fuel injector problems

Fuel injectors in the L67 can get clogged or fail, leading to poor fuel economy, rough running, and performance loss.

Crankshaft position sensor failure

The crankshaft position sensor can fail, causing the engine to stall, misfire, or not start at all.

Worn timing chain

Over time, the timing chain in the L67 can stretch or wear out, leading to timing issues and potential engine damage if not addressed.

Pcv valve issues

A faulty PCV valve can lead to excessive oil consumption, poor engine performance, and increased emissions.
