V8 engines can generate a lot of heat, and an older model like the 1982 Mercury Capri with a V-shaped configuration may have cooling system issues, such as a failing radiator, water pump, or thermostat.

The Central Fuel Injection/2V 2BBL system can develop problems like clogged injectors, faulty sensors, or a failing fuel pump, leading to poor fuel delivery and performance.

Older engines, especially those with higher mileage, are prone to developing oil leaks from gaskets and seals, such as valve cover gaskets, oil pan gaskets, and rear main seals.

With an older V8 engine, components like the distributor, spark plugs, and ignition coils can wear out, causing misfires, rough idling, and starting issues.

The exhaust manifold gaskets or the manifold itself can develop leaks, causing exhaust noise, reduced engine performance, and potential exhaust fumes entering the cabin.

Over time, the timing chain and its associated components (sprockets, guides, and tensioners) can wear out, leading to poor engine timing, noisy operation, and potential engine damage if not addressed.

The older intake manifold and vacuum hoses can develop cracks or leaks, causing rough idling, poor acceleration, and increased fuel consumption.

The gaskets and seals in V-shaped engines like the Ford V8 can wear out over time, leading to oil leaks, especially around the valve covers, oil pan, and timing cover.

Due to the compact design of V-shaped engines, especially in older models like the 1986 Mercury Capri, cooling system components like radiators, water pumps, and thermostats may fail, causing overheating.

The electronic fuel injection system in the 1986 model can sometimes lead to problems with the ignition system, such as faulty ignition coils, spark plugs, or distributor cap issues.

Electronic fuel injection systems can suffer from clogged or malfunctioning fuel injectors, leading to poor engine performance, misfires, and reduced fuel efficiency.

The complexity of the V8 engine with electronic fuel injection can result in vacuum leaks from deteriorated hoses and gaskets, causing rough idling and poor acceleration.

Over time, the timing chain or belt in a V8 engine may wear out or become loose, leading to issues with engine timing and potentially causing severe engine damage if not addressed.

The V-shaped configuration can lead to uneven heat distribution, causing the exhaust manifolds to crack, which can result in exhaust leaks and reduced engine performance.

The electronic components in the fuel injection system, such as oxygen sensors and throttle position sensors, can fail and lead to issues with engine performance and fuel economy.
