How do You Diagnose and Fix Ford 4.2 Liter V6 Engine Problems?

As you can see from the above table, some of these major problems have similar signs. And this makes it hard to decide which problem your engine is experiencing.

In this part, we’ll show you how to easily diagnose and fix common Ford 4.2L V6 engine problems.

To do so, we’ll take a deeper dive into each of the above problems, analyze what causes them, signs to look for, and the best possible fix.

#1. Ford 4.2L V6 Engine Oil Pan Gasket Issue

One of the most common troubles with Ford 4.2L V6 is the oil gasket pan failure. As you may already know, a car engine features many individual parts through which the engine oil must circulate.

This oil must be kept inside the engine, and this is where the pan gasket comes in—it creates seals that keep the oil from escaping out of your car engine.

Unfortunately, the gasket undergoes normal tear and wear as your car runs. And when your engine covers between 20,000 t0 50,000 miles, the gasket becomes completely worn out and unable to form a seal in the oil.

The result is an oil leak with the following additional symptoms:

  • Engine overheating
  • Oil level quickly going down
  • Oil leaks beneath the car
  • Smoke emerging directly from your engine or the exhaust pipe
  • The check engine warning light coming on

Solution:

The best solution here is to replace the gasket pan as soon as possible if you notice a handful of the symptoms above. And don’t forget to fill up your engine with oil if the levels.

Remember, each truck has recommended oil capacity, whether it’s a Ford or Honda Ridgeline oil capacity, so check your owner’s manual for more details.

#2. Ford 4.2L V6 Engine Timing Cover Gasket Issue

The timing gasket is tasked with timing the timing belt/chain attaching the camshaft to the crankshaft. This way, it allows your engine valve to close and open at the correct time during the internal combustion process.

On top of this, the cover helps keep away dust from entering your car engine and completes a 100% airtight seal.

Unfortunately, this gasket is notorious for failing in Ford 4.2L V6 engines. When the gasket wears out, it may cause your car to stop running abruptly (this is the most common symptom of a failing timing gasket).

Additional signs you should look out for include the engine running rough knocking sound near the engine front part and oil leaks in the center of your vehicle. The check engine light is also likely to come on.

Solution:

One way you can fix the timing cover gasket issue in your Ford v6 engine is to restore it. An even better alternative would be to replace it with a new high-quality gasket.

#3. Ford 4.2L V6 Engine Intake Manifold Gasket Issue

The issue of intake manifold gasket has been prevalent in Ford V6 engines from the word go. The manifold gaskets help seal the manifold against the engine cylinder heads.

When the gasket goes bad, common signs to expect include engine misfires, coolant leaks, overheating engine, and a reduction in power, fuel economy, and acceleration.

Solution:

Replace the bad manifold gasket. This is a cheap fix as the gasket isn’t costly. However, the installation cost is a bit high, so you shouldn’t be surprised if your mechanic charges you a labor cost that’s higher than the gasket price.

#4. Ford 4.2L V6 Engine Exhaust Manifold Leaks Issue

The exhaust manifold leak is another major issue many Ford 4.2 liter v6 engine car owners have experienced. This issue puts forth several symptoms that are key to helping you diagnose the underlying problem.

If you want to easily diagnose the exhaust manifold issues with Ford 4.2L V-6, give it an ear and listen for a repetitive ticking noise (especially when the engine is cold).

Other symptoms related to exhaust manifold leaks include;

  • A vibrating gas pedal.
  • The presence of exhaust fumes in your car cabin.
  • A burning smell coming from the engine bay.
  • A significant decrease in acceleration, power, and even fuel efficiency.

Solution:

The fix for a cracked exhaust manifold is to take it out and repair it. If it’s beyond repair, then you should just replace it with a new one. You should also replace any faulty seals and gaskets to ensure you fix the problem fully.

#5. Ford 4.2L V6 Engine Oil Pump Issue

The oil pump is a crucial part of your engine responsible for sucking out oil from the pan and then pumping it through the oil filter and onto the bearings.

When the pump develops issues, the check engine light will illuminate to alter you the oil pressure is low, due to an issue with the oil pump.

Additional signs to look out for include engine overheating, engine burning oil, leaks, unusual pump noise, and valve train noise.

Solution:

Try using high-viscosity engine oil to see if it solves the issue. if that doesn’t work, you may need to buy a new oil pump to solve the problem once and for all.

#6. Ford 4.2L V6 Check Engine Light On

Ignoring the check engine light is never a good idea as you may pay heavily for it later on. If the engine light is flashing, then it is warning you of a critical problem that needs immediate action. In this case, you should stop driving your car immediately to avoid further engine damage.

How Reliable is The Ford 4.2L V6 Engine?

If you’re wondering whether Ford 4.2 L V6 engine is reliable given all the problems above, this is your part.

The Ford V6 engine is more reliable than earlier Ford engine models and boasts a simpler mechanical configuration compared to the modular motors.

For instance, earlier engine models had issues with spark plugs, but this isn’t so with the V6 engine; it comes designed such that its spark plugs properly secure to engine cylinders for maximum effectiveness.

Even better, the V6 engine utilizes an iron block and heads, which helps ensure a more dependable, longer-running motor.

Note that V6 being the base engine means low trim levels, explaining why it is common in inexpensive trucks. Any work-grade truck with crank windows, manual locks, fixed sides, and rear windows will find this engine reliable.

However, one thing to keep in mind about the V6 engine is that it requires no balancing shafts that help neutralize the force produced when driving your car.

The result is heavy vibration, which significantly reduces the engine reciprocation efficiency.
