V8 engines, particularly in older models like the 1994 Buick Roadmaster, are prone to oil leaks from the valve cover gaskets, oil pan gasket, and rear main seal.
Overheating
The cooling system in older V8 engines may struggle to maintain optimal temperature, leading to potential overheating issues, especially if the radiator or water pump is failing.
Ignition system issues
Wear and tear on the distributor, spark plugs, and ignition wires can lead to misfires and poor engine performance.
Fuel injector problems
Clogged or malfunctioning fuel injectors can lead to rough idling, poor fuel economy, and reduced engine performance.

Exhaust manifold leaks
Cracks or gasket failures in the exhaust manifold can lead to exhaust leaks, causing noisy operation and potential exhaust fumes entering the cabin.
Vacuum leaks
The V8 engine relies on a series of vacuum lines and components that can deteriorate over time, leading to rough idling and poor engine performance.
