Most common problems:

Oil leaks

V-shaped engines like the LH2 in the 2006 CADILLAC XLR can develop oil leaks from the valve cover gaskets or oil pan gasket due to aging seals and gaskets.

Timing chain issues

The timing chain in the LH2 engine may stretch over time, leading to poor engine performance and potentially serious internal damage if not addressed.

Cooling system problems

V8 engines can generate a lot of heat, and the cooling system may develop leaks or fail if not properly maintained, leading to overheating issues.

Ignition coil failures

The ignition coils in the LH2 engine may fail, causing misfires, poor fuel economy, and rough running conditions.

Intake manifold gasket leaks

The intake manifold gaskets can deteriorate, leading to vacuum leaks, poor engine performance, and check engine light activation.

Carbon build-up

Over time, carbon deposits can build up on the intake valves and combustion chambers, affecting engine performance and fuel efficiency.

Fuel injector problems

Fuel injectors may become clogged or fail, leading to uneven fuel delivery, rough idle, and reduced engine performance.
