How To Perform 6.7 Powerstroke CCV Delete [Full Guide]

Many Ford 6.7 Powerstroke owners and users often wonder whether deleting CCV is a good idea or just a waste of money and ask what benefits or drawbacks they should keep in mind while deleting and re-routing the CCV.

So, in this very article, I have decided to answer all the common queries and clear all misconceptions regarding CCV delete on 6.7 Powerstroke.

Can You Perform 6.7 Powerstroke CCV Delete?  

Yes, anyone with the basic technical and servicing knowledge and expertise can perform CCV delete on the Ford 6.7 Powerstroke.

However better to get your CCV deletion task or re-route task done by professionals. Especially when you are under warranty, do not take risks and visit your nearest Ford dealer or servicing center to get help.

Before moving on to the details of CCV deletion and other relevant information, let me help the new owners understand the actual meaning and purpose of CCV and why this is something they should know.

The Crankcase Ventilation or CCV system is mainly is part of the Positive Crankcase Ventilation (PCV) system. It is responsible for relieving pressure from your 6.7 Powerstroke engine’s crankcase attributed to blown by gases and reroutes the gases back into the engine’s intake manifold so that engine can consume the gases.

This is a necessary process, and the CCV filter is the only major component of the entire CCV system to maintain the whole system functionality.

As a result, sometimes due to excessive crankcase pressures, build-up corrosion, or lack of routine maintenance, this filter turns bad and causes issues like oil leaks, smoke, or poor engine performance.

That is when you need to take a moment to inspect and if needed, change or delete your CCV.

How Do I Know My 6.7 Powerstroke CCV Is Bad? 

Before deciding whether you want to service, delete or re-route your CCV, you need to know and understand how to detect a bad Crankcase Ventilation filter.

When you start to notice that your Ford 6.7 Power Stroke diesel truck is leaking oil, the most obvious culprit is either the crankcase vent or the CCV filter.

Overtimes, the vent or filter can get dirty as well as restrict the airflow and the pressure-relieving capacity of your CCV system.

As a result, when the pressure builds up too high, the gaskets and seals blow up, causing oil leaks. This is a clear sign that your CCV system needs attention and servicing.

Besides that, you may also notice smoke and an unusual smell of diesel or even hear a wheezing sound coming out of the engine.

When you notice that your engine is suddenly consuming too much oil (burning oil) or significantly has poor fuel economy and performance, make sure you check the CCV condition to confirm whether the problem is there or somewhere else.

If you notice excessively high idle, it is another potential indication that something is wrong with your crankcase vent system or filter.

After noticing any of the previously mentioned signs or symptoms, the first thing you need to do is diagnose whether the problem is actually on your CCV or somewhere else since some of these symptoms also indicate a potential problem in other engine components. 

Once you confirm that the problem occurred because of your CCV, you should contact the nearest dealer or Ford service center for the servicing. That is the best option.

However, Ford suggests their customers get professional servicing from their authorized centers.

What Are the Benefits of Deleting 6.7 Powerstroke CCV?    

When you delete or re-route your old or existing CCV, it cleans up your Powerstroke engine bay and also enhances the pressure-relieving capacity of your crankcase ventilation system.

Therefore, no more oil leaks, excessive idling, high fuel consumption, or poor fuel economy and performance drop.

What Are the Drawbacks or Problems of Deleting 6.7 Powerstroke CCV?

Although there is no significant drawback or problems after you delete your CCV, some users still prefer rerouting it over deleting it.

The main reason behind choosing to reroute over deleting is because the CCV routes crankcase vapors back into the intake, which can coat your intercooler with oil. So, they prefer rerouting the CCV to a catch can or just running a hose straight down under the truck.

Another thing that you should keep in mind is that after you install the CCV delete hose, it may still cause oil leaks onto the ground after some time. That is why Ford suggests changing the CCV regularly, just like your routine servicing of the engine.

But remember to be careful and easy on the throttle. Also, expect to burn an excessive amount of oil.
