What Is A Blow-Off Valve (BOV)?

Ford F-150 Ecoboost BOV (Blow-Off Valve) Problem: Reasons And Solutions

The blow-off valve (BOV) on the EcoBoost F150 releases the pressure in the intake system. Basically, it releases it back into the air when the throttle plate is closed.

The compressor wheel is struck by the turbo’s pressure when there isn’t a correct release, which results in a compressor surge.

Eventually, compressor surges lead to forced compressor wheel stopping, longer turbo delay, or possibly an early turbo failure. It should be clear that investing in a high-quality BOV is a wise decision.

What Is The Reason For Blow-Off Valve Noise In Ford F-150?

Your Ford F150 EcoBoost’s plastic blow-off valve may be the weakest link in the engine’s defenses.

Because of that, it is prone to breakdowns that leave you with annoying noise.

Keep reading to find out what is causing the BOV noise.

1. Oil

Your car’s engine oil is essentially its lifeline. It keeps them cool while in operation, stops corrosion, and lubricates crucial moving parts.

Pure, high-quality oil must be continuously available for the turbocharger. Lack of oil (oil hunger), the wrong kind of oil, or poor-quality oil will cause pollutants to accumulate in the engine.

The inside of the turbo might sustain abrasive damage as a result. This may be the root of the valve’s F150 EcoBoost noise.

2. Damaged Seals

Here, the seals between the compressor and the engine start to leak or fail. Into the exhaust system, the oil will leak. The turbo needs to work harder to increase the air pressure.

This issue is also known as overspeeding. Ultimately, it will generate noise and reduce the turbo’s efficiency.

3. Deposits of Foreign Material

The two fundamental components of a turbocharger are the pump at the front and the generator at the back.

Occasionally, foreign objects like dirt, leaves, and tiny stones can enter the turbo through the compressor intake or the turbine inlet.

The foreign object often originates from the compressor housing and travels to the air filter. In contrast, the engine is typically the problem when a foreign item damages the turbine.

If foreign things begin to degrade them, the turbo’s compressor tires or turbine blades may suffer.

Your air filter must be maintained and changed frequently to prevent this. You could also check your turbo for debris.

What Can You Do About The Blow-Off Valve (BOV) Noise?

If your turbocharger fails, you’ll still be able to drive your car, but engine failure won’t be long behind, so only continue if it’s essential.

As soon as you observe any warning signs described above, have your Ford F-150 examined by a qualified technician. The longer you neglect it, the worse it will get (and the more it will cost you).

In general, this doesn’t mean that the cost will be ridiculously high. However, it can be higher the longer you wait.

What Are The Problems With EcoBoost?

Overheating, oil leakage, and turbocharger failure are the most frequent problems. 

However, with the proper maintenance, you may avoid these issues. 

Maintain regular spark plug maintenance, oil changes, and coolant level checks. Allow your engine to breathe, and keep an eye on the belts.

How Can I Tell If My EcoBoost Turbo Is Malfunctioning?

There are several signs that your turbo is malfunctioning. 

The signs are:

  1. Losing power
  2. louder, more gradual acceleration,
  3. sustaining high speeds is challenging,
  4. smoke that is blue or gray emerging from the exhaust,
  5. the dashboard engine light is on.

How Does EcoBoost Rattling Happen?

The absence of initial oil pressure feeding the VCT before beginning is the primary source of this rattling. 

Occasionally, this rattling can be brought on by an oil filter without an anti-drain back design to stop all the oil from draining into the crankcase, but in this case, that doesn’t stop the problem.
