Ford 4.2l V6 Engine Problems And How To Fix

Do you have any experience with Ford 4.2l V6 engine problems? The truth is most drivers using this engine can share the same concern. 

Ford 4.2l V6 engine, or the Canadian Essex, aimed to improve the old versions in terms of durability, lifespan, and performance. However, this project wasn’t successful. As a result, Ford decided to eliminate this line in 2008. 

We will discuss the problems with Ford 4.6 liter engines that we have encountered here. Most of them can affect your car’s performance. Let’s get into the details! 

Ford 4.2l V6 Engine Problems

Ford 4.2l V6 Engine Problems 

The most common issues with the Ford 4.2l V6 engine occur with its intake manifold gasket, exhaust manifold, time covering gasket, and oil pump. 

There are reasons for each issue; you can solve them by replacing the broken part. In fact, swapping the engine in vehicles is common. Many models, like Honda Del Sol (2), allow you to do so to achieve the best performance. 

Intake Manifold Gasket Issues

This problem was common when the Ford 4.2l V6 engine came out. Its outdated lower intake manifold gaskets remained a headache for drivers until January 2008. 

To tackle this issue, Ford employed a thicker gasket that could produce a tighter between the manifold and engine. 

The new intake manifold gasket aids in preventing oil leaks. Even so, it may break down sometimes. The signs include overheated engine and coolant leaks.

Besides, due to the damaged intake manifold, the air/fuel ratio in the engine will not be correct, leading to the fuel color change and backfiring. 

How to solve it?

If you have problems with the intake manifold gasket, replacing it will be the best solution. This component doesn’t cost much, but the labor is quite high because of the complicated installation.

Exhaust Manifold Issues

Exhaust Manifold Issues

The exhaust manifold sits on the Ford 4.2l V6 engine and is the first component of its exhaust system. It’s responsible for directing exhaust gas from every cylinder and hose toward the catalytic converter.

Nevertheless, the Ford 4.2l V6 exhaust manifold soon weakens and causes numerous issues. For example, if it leaks, you can hear a ticking noise while the engine is still cold. However, a damaged exhaust stud may also cause the noise. 

Other signs of the leaks are pedal vibration, cabin exhaust gas, burning smell, and power loss. There can be a reduction in fuel economy and acceleration, too. If you don’t fix it soon, the Ford 4.2l V6 engine may fail. 

How to solve it?

Remove the damaged exhaust manifold and fix it immediately if it leaks. And if it’s impossible to repair because the damage is too severe, replace it. 

On the other hand, if you detect problems in the seals or gaskets, replace them, too. The Ford 4.2 v6 engine replacement will ensure that your engine can perform its best.  

Oil Pump Issues

The oil pump, as its name implies, pumps oil from the pan onto the bearings. Because the pump can last long, drivers don’t often replace it. However, the pump of your Ford 4.2l V6 engine may spoil quickly. 

When the oil pump fails, the oil pressure will drop, turning on the oil light or engine light. You need to check your oil level using a dipstick and add oil if it’s low. 

If the lights are still on even when you have added oil, the oil pressure may not be the cause. In this case, check for other symptoms, such as an overheated engine and strange noise in the oil pump. 

How to solve it?

Switching to higher-viscosity oil will help fix this problem. You can add the oil to your Ford 4.2l V6 engine to see if it has recovered. However, consider replacing the oil pump if the new oil can do nothing for your engine.

Timing Cover Gasket Issues

Timing Cover Gasket Issues

The timing cover gasket is in charge of protecting the timing belt connected to the crankshaft. It helps open and close the engine valves at the right time during combustion. 

Another role of the cover basket is sealing. Thanks to its airtight seal, dust can’t enter your Ford 4.2l V6 engine. 

Sadly the seal may break down sometimes due to the damaged timing gasket cover. As a result, your car may stop abruptly. Other issues include oil leaks and rough idling. 

How to solve it?

You have two options to solve a timing cover gasket issue: repair and replacement. You can consult your mechanic for the best solution.  

Oil Pan Gasket Issues

Oil flows through multiple components in your car engine. There are seals between them so the oil can stay within the engine. The oil pan gasket is among the seals, which keeps them from leaking. 

Over time, the seal will wear out. Things worsen if you have a Ford 4.2l V6 engine because its oil pan even wears quicker. 

When the seal degrades, there will be leaks under your automobile. Smoke may also emanate from the tailpipe or engine. Other issues are oil drop and overheated engine. 

How to solve it?

You can apply an oil leak product to the engine oil to restore the oil pan gasket. But ensure that its initial size and shape can recover after being cracked or shrunken.

Another solution is to replace the worn-out oil pan gasket. Remember to buy it from reliable stores and install it correctly.

Compared to modular engines, the Ford 4.2l V6 model is reliable with less complex mechanical construction. It creates a dependable, long-running power by using an iron block. 

The Ford 4.2l V6 engine is often used in low-cost trucks because its base engine is V6 with a low trim level. Hence, work-grade vehicles with rear windows, fixed sides, and manual locks will like this engine. 

On the other hand, the Ford 4.2l V6 engine doesn’t need balancing shafts to manage the force generated when running. Thus, there will be heavy vibrations, which may reduce the engine’s reciprocation efficiency.

Do People Still Use Ford 4.2l V6 Engine?

The Ford 4.2l V6 engine is no longer in production because Ford has eliminated it since 2018. Yet, there are still some Ford vans and vehicles with this engine. 

Drivers use this engine because it’s durable and reliable if properly maintained. Besides, they may need a cheaper and more straightforward engine design rather than sophisticated engines for their vehicles. 

The Ford 4.2l V6 engine requires more frequent maintenance and repairs as it ages. Moreover, it’s not easy to find the proper replacements. 

As a result, if drivers have severe problems with their Ford vehicles, some may swap the engine with a newer and more modern motor.


Ford 4.2l V6 engine problems will cause trouble when you are in the middle of the road. For example, the exhaust manifold, oil pump, or intake manifold gasket may break down.

The common symptoms of those issues are the overheated engine and strange noises. If not fixed soon, the whole engine may fail.
