When compared to several Ford engines, it is a reliable long-running motor. At a time, it was rated as one of the most reliable engines for Ford F-150.

Nevertheless, you can experience issues with it, and that’s why we created this piece to help you.

05 Unexpected Ford 4.2L V6 Engine Problems

There are many problems that you can encounter with the Ford 4.2-liter V6 engine. Five common problems are treated below with their solutions.

01. Timing Cover Gasket Problem

Ford 4.2L V6 engine’s timing cover gasket problem is a conventional thematic one.

The timing cover’s basic function is to protect the timing chain or belt connecting the camshaft to the crankshaft.

In addition, it helps with the timely opening and closing of the valve of the engine when internal combustion is going on.

It forestalls dust from gaining access to the engine and fulfills air-tight sealing.

If your timing cover gasket corrodes, your vehicle may stop suddenly. Oil may start leaking beneath your car, and you will notice the leakage at the center.

Besides, another symptom of the timing gasket cover problem is that your engine will start running rough.

You may notice a knocking sound close to the engine’s front line. Most importantly, the check engine light may turn on, and you should not ignore this to avoid deterioration.

02. Intake Manifold Gasket Problem

This problem is usually due to the use of old-fashioned lower intake manifold gaskets for the engine before the 15th of January 1998.

After this date, Ford started using a more solid gasket, which helps in creating a more sturdy bond between the manifold and engine.

Manifold gaskets’ major role is to seal the manifold against the head or heads of the cylinder.

Some symptoms you may notice if your has this problem are engine misfiring, reduction in acceleration, power, and fuel economy.

Also, there may be coolant leakage as well as overheating of the engine.

03. Oil Pan Gasket Problem

There are many components in an engine and oil circulates through every component. That’s why each component comes with seals to keep the oil within the engine.

Oil pan gaskets are seals, and they work in preventing oil from leaking out of the engine.

It is normal for the oil pan gasket to wear and tear when used constantly.

After covering between 20,000 and 50,000 miles, there is every possibility that the gasket will begin to wear, hence, it won’t be able to seal the oil properly.

Some of the signs you will notice in this type of situation are apparent oil leakage beneath the vehicle and overheating of the engine.

Also, smoke may be coming from the exhaust pipe or directly from the engine. There may be a sharp reduction in oil level, and the check engine light will beep.

04. Oil Pump Problem

One of the basic components of your vehicle’s engine is the oil pump. It helps in sucking oil from the oil pan with subsequent pumping into the bearings through the oil filter.

In most cases, there is no need to change the oil pump, identifying problem signs should not be overlooked.

The most prevalent sign is the turning on of your check engine or oil light. You should not ignore this because it can lead to extra expenses for you in the future.

Especially when the check oil light beeps, because it does not beep frequently.

It may be a sign that your oil pressure has gone down, and there is an issue with the oil pump. Also, your oil may be leaking, and the engine may be burning oil.

Furthermore, you may notice an increase in the operating temperature of the engine. The valve train and oil pump may be making an unusual noise.

05. Exhaust Manifold Leaks

There are several-exhaust manifold leak signs that will suggest that there is an issue with your Ford 4.2L engine. The first one, which is very prevalent is that you will hear some pulsating noise.

Usually, you will hear the noise when the engine is cold. This is because the heating up of the engine leads to the discharge of hot air via the exhaust.

Thereafter, the manifold’s meal stretches and encloses the manifold’s defects, which is more probably a crack.

Also, when an exhaust stud is broken, it can lead to undesirable noises. You may notice exhaust fumes but this is not common.

Exposure to heat and moisture due to constant use can lead to wear and tear, which can make them break.

Besides, the closeness of one of the studs to the firewall can cause an air gap when it breaks.

In a situation like this, there will be excessive deterioration of the gaskets, which will lead to louder pulsating noise.

At this juncture, there is every possibility that you will be experiencing the smell of exhaust fumes. Undoubtedly, exhaust fumes should be fixed quickly because it is a safety issue.

Another symptom that you will notice is the vibration of the gas pedal. Also, there may be a conspicuous reduction in acceleration, power, and fuel efficiency.

These are pointers to the fact that your exhaust manifold is leaking.
