V6 engines, especially older models, are prone to oil leaks from gaskets and seals as they wear out over time.

The 1991 Dodge Stealth's V6 engine relies on a timing belt, which can wear out and potentially fail if not replaced according to the maintenance schedule.

Intercooled engines can have issues with the intercooler and cooling system, leading to overheating if not properly maintained.

V6 engines can be susceptible to head gasket failure, which can cause coolant leaks and engine overheating.

Older Dodge Stealth models may experience issues with the ignition system, such as worn spark plugs or failing ignition coils.

The fuel injectors in the V6 engine can become clogged or fail, leading to poor engine performance and reduced fuel efficiency.

Vacuum leaks can occur in various parts of the engine, leading to rough idling and poor engine performance.

If the model includes a turbocharger, it may experience wear and tear over time, leading to reduced performance and potential turbo failure.

V8 engines, especially in older models like the 1991 Dodge Ramcharger, are prone to developing oil leaks from valve cover gaskets, oil pan gaskets, and rear main seals.

V8 engines can generate a lot of heat, and in older models, the cooling system components (like the radiator, water pump, and thermostat) may fail, causing the engine to overheat.

High mileage V8 engines may experience issues with the timing chain or belt, leading to poor engine performance or even engine failure if not addressed.

With age and use, the fuel injectors in a V8 engine can become clogged or fail, leading to poor fuel economy and engine misfires.

Components such as the distributor, spark plugs, and ignition coils can wear out over time, causing misfires, poor starting, and reduced performance.

The intake manifold gaskets on older V8 engines can deteriorate, leading to vacuum leaks that affect engine performance and idle quality.

V8 engines, especially those subjected to heavy use, may develop cracks in the exhaust manifolds, leading to exhaust leaks and reduced performance.

Over time, carbon deposits can build up in the combustion chamber and on the valves, affecting engine efficiency and performance.

High mileage V8 engines may suffer from worn main or rod bearings, leading to knocking noises and potential engine damage if not repaired.

Over time, the piston rings and cylinder walls can wear, leading to reduced compression and poor engine performance.

If the model includes a turbocharger, it may experience wear and tear over time, leading to reduced performance and potential turbo failure.

Older Dodge D-Series models are prone to oil leaks, especially around the valve cover gaskets and oil pan gasket.

Problems with the fuel pump or fuel injectors can cause poor engine performance or starting issues.

Radiator or water pump failures can lead to engine overheating.

Issues with the ignition coil, distributor, or spark plugs can cause misfires or engine stalling.

A worn timing chain can lead to poor engine performance and potentially severe engine damage.

Leaks in the vacuum system can cause rough idling and poor acceleration.
