Problems:

Oil leaks
V8 engines, like the one in the 2008 Mercury Grand Marquis, often develop oil leaks from valve cover gaskets, oil pan gaskets, and rear main seals over time. This can lead to oil dripping onto other engine components.
Spark plug issues
High-performance V-shaped engines may experience spark plug fouling or wear more quickly, leading to misfires or poor engine performance.
Cooling system problems
The cooling system in V8 engines can sometimes be less efficient, leading to overheating issues. Problems can arise from radiator leaks, faulty water pumps, or clogged coolant passages.
Timing chain wear
In some V8 engines, the timing chain can stretch or wear out over time, causing poor engine timing, rough idling, or even engine failure if not addressed.
Fuel injector problems
V8 engines can experience issues with fuel injectors becoming clogged or failing, leading to a loss of power, rough running, or increased fuel consumption.
Intake manifold gasket failure
The intake manifold gaskets on V8 engines can fail, causing coolant leaks and potential engine overheating issues.
Engine mount wear
The high power output of V8 engines can lead to premature wearing of engine mounts, causing excessive vibration and noise.
