6.7 Powerstroke CCV Delete Instructions Explained [Easy Steps]

Out of all the engines out there, the 6.7 Powerstroke engine is still one of the most reliable. It is still arguably the best truck engine, according to many users of the Ford trucks. And a must-have for the engine is the CCV mod.

The mod will save you a lot of time and money in the long run. And the service it provides to your engine is beyond mentioning. That’s why today we will learn about the 6.7 Powerstroke CCV delete instructions. But before that, let us understand some of the things.

What Is the CCV Mod?

CCV stands for Crankcase Ventilation, and the mod is basically a filter that is used on the engine to maintain it a little better and increase its longevity. The filter prevents oil droplets from going back into the intake system again. And thus, it plays a very big role in reducing the oil deposit in the engine.

Due to this, it also plays a role in reducing oil usage in the engine. In this way, it allows the engine to comply with the EPA emission standards, which can be really strict at times.

When to Install 6.7 Powerstroke CCV Delete?

The CCV will save your engine a lot, but the filter itself also has a lifespan. And beyond that, the delete should be installed immediately. The filter usually goes bad after putting in around 67000 miles.

Well, the symptoms you should keep an eye out for to know when to install your Powerstroke CCV mod delete are:

Leaking Oil

You will start to notice that the filter is leaking oil. This happens if the filter starts to accumulate a large amount of dirt on itself, restricting the airflow. And that results in the escalation of a lot of air pressure making the seals blow up. Ultimately, the oil starts to leak.

Smell Diesel

You might start to smell the odor of diesel when the flow of the leak is too high, and that is when your filter has really given up. This is a sign that you need to immediately install the CCV mod delete.

Frequent Fueling

If you need to refill your fuel way too often, that is a bad sign. That basically means that if you notice that the fuel you are getting is not lasting a long time, you should install the delete. This mainly happens because the oil is getting leaked instead of getting used.

Poor Performance

If your vehicle’s performance is discernibly going down, that could be a big symptom of getting it done as soon as possible. A reason behind the vehicle not performing properly could be the oil that is getting leaked out.


If you notice any smoke coming out of your 6.7 Powerstroke, that could be a big sign as well. The smoke might be partnered up with a wheezing sound in many cases.

Now that you know when to do it, it is high time you know how to install 6.7 Powerstroke CCV delete.

6.7 Powerstroke CCV Delete Instructions

Before deleting your CCV, of course, you have to take it out of the box. And that can be a little hassle. But after you do that, you have to follow some steps to delete your Powerstroke CCV.

You have to follow them very attentively if you want to do all these yourself and not call a technician to do it. This will save you some money and a lot of time as well.

Step 1: Remove the CCV

It is not easy to remove the CCV. You will have to unplug 4 studs to get it out. But before that, you will also need to unplug the fuel filter, fuel rail, and some other pipes to make more space for you to get the CCV out.

The box has 4 studs of 8 mm, and they need to be removed as well.

Step 2: Ready Your Kit

First things first, you have to prepare the kit that you will be using to start the procedure. There are many kits on the market, for example, the SPE CCV kit.

However, all of them are more or less the same. Usually, the kit will include an oil block plug off, a hose, an adapter for the hose, hardware, and a hose clamp.

Step 3: Install the Oil Block Plug Off

First, lubricate the O-ring with some oil. Even though you might think there is some oil on the bottom, lubrication is still necessary. It will prevent the seal from tearing when you push it down. This will be bolted out using one bolt.

Step 4: Connect the Adapter

Connect the adapter for the hose to the port of crankcase pressure to come out of the engine. Put some petroleum jelly on the adapter before putting it in. Tighten the adapter to make sure the adapter stays on there.

Then connect the hose itself to the adapter and let the hose lead to the bottom of the vehicle. The adapter will need to be bolted out using two bolts.

Step 5: Install the Hose Clamp

Before installing the hose clamp, you have to remove the existing pipe. And that is especially difficult to remove. But you can get it done way easier if you have a razor blade. Just cut it and install the hose clamp in place.

Step 6: Install the Can Catch Opener (Optional)

This does not really come with any kit; instead, it is more of an add-on to your system. It also goes inside the port from where the crankcase pressure comes out. And then the adapter goes on top of this.

It basically creates a baffle and oil separator, with the baffle side creating a catch can.

But this is not absolutely necessary – rather an optional addition to your vehicle to make it work even better and more efficiently.

After doing all these, plug all the things you have undone, and you are good to go. Check under the vehicle to see if too much oil is leaking to know if you have done everything correctly.

Why Should I Install My 6.7 Powerstroke CCV Delete?

Since the oil leaking will be stopped, the truck’s performance will be noticeably better. And the performance will also be paired with a lower cost since no oil will get leaked out. There will also be a reduction in excessive idling.

Some Potential Drawbacks of Powerstroke CCV Delete

Even though it is generally a really good and positive thing to do for your vehicle, there are some potential drawbacks that might happen as a result of doing it.

However, these are not a hundred percent proven and should be taken with a grain of salt. The following are the potential drawbacks of Powerstroke CCV delete:

  • There might be some stress on the parts while installing the delete since the crankcase pressure might go up
  • The hose might leak oil after a while of installing the delete, but this usually stops
  • There might be a lot of pressure on the turbo seals leading to damage to the shaft seals in the turbo

But these claims are not scientifically backed, and there is no real proof of any damage being caused to the engine or the seals. A little bit of oil leakage might happen, but that is normal and temporary.

Final Words

The CCV mod is a great one that will save you a lot of time and mental stress. And so, it is good to know how and when to install the delete for proper maintenance of your vehicle.
