Servicing Your CorkSport Oil Catch Can for Winter

Servicing your OCC

   We at CorkSport hope all of you are staying safe, warm, and happy during this winter season.  As the weather changes, so do components in your Mazda.  Making sure to take the time to properly do some maintenance on your Mazda will go a long way. Whether you own a Mazdaspeed or an NA Mazda, I wanted to make sure and take a little bit of time for you guys to explain how to service your CorkSport oil catch can, and why that is important as the weather starts to become colder.



Why Use an Oil Catch Can

Having an oil catch can on your Mazda is always a good idea.  Over time, the engines will start to wear down allowing oil to blow by the piston rings.  Due to this, you can have oil pass back into your intake causing unwanted smoke to come out of the tailpipe.  Keeping that oil from contaminating the engine will result in a much cleaner engine over time.  

Also, having an OCC on your car is a good way to tell if you have internal engine issues, or if you have a bad PCV.  We recommend draining your catch can every oil change.  If you see a bunch of oil in your catch can, then you know, it’s time to start looking into why the can is filling up with oil.



Servicing Your Catch Can for Winter

     Making sure to catch all the nasty vapors an engine puts off is an important thing to do in regards to longevity of the engine.  However, making sure the CorkSport OCC is working properly is just as important.  The reason why this is important is that you want to make sure your oil catch can continue to filter out the nasty vapors otherwise you will dirty up your engine faster than you want.  However, it is very easy to maintain a good working oil catch can.  

Follow these couple steps below on getting that catch can back up to a new status:
  1. Remove top dipstick
  2. Remove bottom plug
  3. Spray Brakleen through dipstick hole
  4. Allow draining
  5. Repeat a couple of times to ensure your can is clean
  6. Check all rubber hoses.  Make sure none of them are cracked or look dry



Why You Should Service Your Oil Catch Can

   Even though oil/gas takes really cold temperatures to freeze, water vapors still make it into the system which most definitely can freeze.  The last thing you want is to have your oil catch can no longer able to catch the nasty vapors the engine puts off.  


If you have a frozen can, those will pass by the baffle and make it into the intake.  Make sure to drain that OCC, and continue to drain it every time you change your oil.  As long as you do that, there should be no problem with having your catch can freeze, or getting too dirty.

Keep on driving Mazda fam!



Product Release – SkyActiv Aluminum Oil Catch Can

CorkSport – SkyActiv Aluminum Oil Catch Can


CorkSport is proud to announce the SkyActiv Aluminum Oil Catch Can. An excellent product to help increase the life of your engine, helping capture the oil and contaminants is now available for the SkyActiv.

Specifically designed to to fit the 2012-2013 Mazda 3 SkyActiv models. Easy installation and a direct OEM fitment.

An oil catch can is designed to “catch” unwanted vapors that are in your crankcase and PCV system and prevent these contaminates from entering your motor. With no catch can installed, you have the potential to get build up in the intake manifold causing dirty valves and poor compression.

For a good understanding of how the Oil Catch can can add years onto the life of your motor check out this past blog write up.

The Inner Workings of the CorkSport Oil Catch Can

Since the release of our Oil Catch Can we have had a lot of questions about how our set-up functions. Most understand the basics of what the OCC does, but want to know more about how our OCC does it.

The Basics

For the last 20 or so years, all cars have had some sort of PCV system installed to re-burn unwanted vapors from your crankcase instead of venting them to the outside world. This system is based on vacuum. When the engine is running, the pistons are happily moving up and down. There is a small amount of compression that is lost into the crankcase passing by the rings. This excess air will cause pressure in the crankcase to slow down the pistons from going up and down and build up oil vapors that create frothing of the oil. There are also small amounts of condensation that get trapped in the crankcase and you don’t have to be a rocket scientist to know water and oil don’t mix.

An oil catch can is designed to “catch” unwanted vapors that are in your crankcase and PCV system and prevent these contaminates from entering your motor. With no catch can installed, you have the potential to get build up in the intake manifold causing dirty valves and poor compression.

How the Mazdaspeed 3 PCV System Works

A Mazdaspeed 3 has two PCV lines. One goes from the cam cover to the intake and one goes from the crank case to the intake manifold. Why the two locations you ask? Well they go to the closest vacuum source, but in a turbo car you will not have vacuum when you are in boost so a check valve closes and stops the crankcase from being pressurized and boost being lost.

Improving the Design of the CorkSport OCC

Most Oil Catch Cans include a PCV valve in the set-up for turbo vehicles, as ours did until just recently. So why does CorkSport no longer have a Check Valve on our Oil Catch Can setup? This is a great question.

We noticed that by adding the PCV check valve to the oil catch can, the OCC worked less effectively because when the check valve closes (the car is under boost) the catch can is no longer able to do the same job of “catching” the vapors. When your car is under boost is the time the catch can should be working the hardest to prevent those contaminates from entering your engine. Instead it is just sitting there waiting for the PCV valve to open back up.

We decided to cap the intake manifold and pull vacuum through the intake so both cam and crank case vapors are trapped in the OCC leaving your motor the cleanest it can be. Now, the CorkSport Catch Can will be working to eliminate those vapors all of the time without the restriction of a PCV valve to prevent it from being able to remove contaminates while your car is under boost.

So why not cap the intake and the intake manifold and have it vent to atmosphere?

There are several reasons this is a bad idea and being friendly to mother nature is only one of them. Yes, you might sleep at night better knowing you are not hurting the environment but this is not the only reason to plumb the catch can back into the intake.

1. The intake vacuum helps draw vapors out of the motor by creating a low pressure system to force the vapors out. Without the vacuum the vapors can only be forced out by the pressure in the crankcase. This is unreliable and inefficient. Think of how much easier it is to get air into the motor under pressure (ie turbo). It only makes sense that the opposite would be true about getting it out and it would be much easier to achieve under vacuum.

2. Metered air passes through the MAF sensor before entering the engine, then a small amount is passed by the rings and enters back into the intake or intake manifold. If you do not route the PCV back into the intake manifold then that calculated air is “poof” let out into space causing your fuel trims to be off.

If you think you can tune around this you are correct, sort of. As the rings degrade you will have a small amount of additional air passing by the rings. Time to re-tune. The rings degrade some more, then time to re-tune again. I think you get the picture. Eventually you forget to keep up on this and your fueling is off enough to cause a check engine light or worse. Zoom-Zoom-Boom!

This is the nature of a MAF sensored car. There is a good reason that Mazda has everything hooked back up to the intake. Your car will be happier in the long run doing this.

Next we will be rolling out a new and improved turbo inlet pipe for those who are running a stock or non-CorkSport intake system. The newest version of our turbo inlet pipe has been redesigned to provide seamless fitment with OEM or other aftermarket intake systems by replicating the fitment of the factory TIP to the intake while maintaining all of the characteristics that have made our turbo inlet pipe a top selling product.

We will also be introducing our staged intake systems with the addition of a stage one CorkSport short ram intake without turbo inlet pipe for those that want to upgrade to a basic package. The stage two intake system will be our number one selling CorkSport short ram intake with turbo inlet pipe and the stage three intake system will be the new CorkSport Cold Air Intake which has been designed to push the filter away from the engine and will have the unique feature of being interchangeable with our short ram intake system for customers wanting to run a cold air intake in the summer and short ram in the winter!

We will also be launching the highly anticipated CorkSport Oil Catch Can early this year. This has gone through several iterations to find the ideal design that would provide functionality and be simple to install. The end result is an aluminum, bolt-on oil catch can that will help keep your intake clean by filtering out the junk that would otherwise end up in your intake manifold and possibly on your valves. You can see a full string on the development of this product on the Mazdaspeedforum.

Also to come early this year is the new addition to our CorkSport LED lighting product line with the CorkSport Mazdaspeed 3 Bumper Lights.

Let’s also not forget our Mazdaspeed Protégé drivers out there, we have something for you as well with Mazdaspeed Protégé Silicone Intercooler Hoses expected to be out soon!

This represents just some of the great products you can expect to see from CorkSport in the coming year!


What’s Going On! CorkSport Development Update

At CorkSport, we are always looking for ways to improve Mazda Performance through the development of new products. We have multiple projects in various stages of development at all times and as one of the lead engineers here, I am kept busy managing the design, implementation and evolution of many of the products introduced into the CorkSport lineup.

Since I started at CorkSport, I have been involved in the testing and final release of some of the new products in the CorkSport line such as the CorkSport Mazdaspeed 3 Lowering Springs and the CorkSport Stub Antenna and I am currently working several projects that we will be releasing over the next few months. Our customers often say that they want to know more about what’s in store for our new product releases and details about how the development process takes place so today I wanted to fill you in on some of the great things going on behind the scenes here at CorkSport.

One of the products I am particularly excited about is the CorkSport Oil Catch Can we are developing for the Mazdaspeed vehicle line. It aims to help filter out the junk that can end up in your intake manifold. One of the main reasons we wanted to develop this product is because the PCV system in the turbo MZR engine has a bad rap and is not known for performing well. Its purpose is to get rid of the particles and gases in the crankcase that get blown by the piston during compression. It helps filter out these particles to keep them from getting mixed in with your oil and from being dumped into the environment. The problem is that these particles get recycled through your engine and recombusted. They also get caked on your intake valves and intake track. In a normal port injected engine this isn’t as big of a deal because the fuel helps wash the deposits away and keep your valves clean. However on a direct injected engine, as found on the Mazdaspeed vehicles, the fuel is injected right into the cylinder and no longer acts as a cleaning agent for the valves so deposits begin to form. The CorkSport Catch Can will filter out the junk that would end up in your intake manifold and possibly on your valves keeping your intake clean. All that is required is that the can emptied with every oil change.

During testing we had the samples removed from the catch can analyzed. The test results shown below reveal just how much junk is entering your engine.

Another pet project I am working on is the development of a FMIC kit that will work seamlessly with the short ram intake on the Mazdaspeed3 and Mazdaspeed6. We have been running the kit on the CorkSport Mazdaspeed3 with great results and have just completed the design of the piping on the Mazdaspeed6 to begin test fitment of that vehicle.

A product that will be entering the lineup in the near future is the CorkSport Rear Sway Bar for the Mazdaspeed 6. We have a test product installed on a customer’s car and it has been performing quite well. Our customer has seen improved handling, faster cornering speeds, and more traction. With the sway bar being a slightly difficult install, I was sure to take lots of pictures during the install in order to provide our customers complete and thorough instructions to make the process a little easier. And of course if a customer runs into difficulty during the install, they can always call us for help.

Most of the products currently under development have originated from product submissions we have received from all of you. If you ever have any ideas for a new product don’t be afraid to submit it. We have a monthly development meeting to evaluate every product submission we receive, so please let us know what you have been wanting for your Mazda!
