2013 - 2019 Cadillac ATS
After installation, Mishimoto recommends checking the contents of the baffled catch can every 1,000 miles until a baseline is established. Oil blow-by accumulation will vary with ambient temperatures and driving conditions. It is important that the contents of the can do not rise above the internal baffle.
This is the most efficient method for protecting your LTG engine from the dangers of oil blow-by. Why buy one, and then the other? Get both the PCV and CCV Baffled Oil Catch Can Kits combined in one. With this complete Mishimoto 2013+ Cadillac ATS 2.0T Catch Can System, you will have an unbeatable setup that effectively combats oil blow-by, keeping your intake, charge pipes, and turbocharger compressor free of oil. To help maintain proper octane levels, prevent blow-by, and reduce potential detonation, we use a patent-pending solution engineered to extract blow-by through utilizing a hidden PCV valve inside the valve cover.
This complete kit uses two catch cans from the PCV and CCV system that are equipped with 50-micron bronze filters, with application-specific mounts and hoses. Your dual billet 6061 aluminum catch cans will mount securely under your hood as if they came that way from the factory, and they both install in under an hour! The Mishimoto 2013+ Cadillac 2.0T Catch Can System includes all mounting and installation hardware, and ships with the Mishimoto Lifetime Warranty.
Our catch cans are different from most air-oil-separator (AOS) systems on a few levels. First, our catch cans are not heated. This means that all of the blow-by is able to condense in the can, including low-octane oil vapors and contaminated fuel vapors. Most AOS systems also drain the blow-by back into the oil pan, while our catch cans trap the blow-by and keep it out of the engine permanently. If you’ve seen what we’ve seen in the bottom of our catch cans, you won’t want that draining back into your oil either.

LITTLE CADDY – CATCH CAN R&D, PART 4: ATS HOSE ROUTING
Today, we’re going to take it back to basics a little bit and look specifically at that whole “transport” element. To go even further back to basics, check out our technical section to see why blow-by is so bad for your engine over time. You know all about the complex, unique parts of this Camaro catch can project, but what about something as simple and ubiquitous as the hoses?
There are many ways to skin a cat, and there are many ways to route a hose. However, as they say, all you really need to know, you learned in kindergarten. Steve took us back to circle time with a clever new way to route houses in a way that’s more visually representative of how the final product will look. It’s just another way to even more confidently nail down fitment on these Camaro parts – or should I say on this ATS catch can?
That’s right folks, we routed our own 2.0T’s hoses already, so this time, we brought our Camaro’s Cadillac cousin into the R&D facility to custom-tailor some stylish new silicone. But more on that later. Let’s start with an update on our blow-by situation.
This R&D Process is Really Blowing By
First, let’s take a second to pretend that I haven’t made that same blow-by joke numerous times before. Now, let’s take a peek at what we’ve got going on in our catch can after another thousand miles or so on the 2.0T.
As you can see, we are continuing to catch a substantial volume of condensed muckity-muck and evacuate it from the system before it clogs up our Camaro’s internals.
Can in the Cadillac
Now that we’ve further re-affirmed just how much blow-by we’re isolating with this setup, it’s even more crucial to ensure that fitment across both these alpha-platform vehicles is like that of a glove. We’ve got the Camaro nailed down, but there’s not quite as much room to work with in the Caddy, which was generously loaned to us by a customer.
This engine bay necessitates not only a new set of hoses, but also a new bracket for mounting the can. We haven’t revealed our exact placement of the Camaro can yet, but we are still working out a couple additional considerations, and may have some other surprises for you in store there –more on that in a future post!
For now, let’s look at the ATS catch can setup. Steve identified the strut tower as a good mounting location, so first, he fabbed up a quick prototype bracket to ensure fitment.
Next, once measurements and clearances got the A-OK, we cut a more presentable bracket on the waterjet.
Hose in the Caddy
With the bracket all squared away, we needed to determine the optimal route for silicone hoses to pass crankcase vapors to and from our catch can. Steve put his thinking cap on, and once recess was over, it was time for arts and crafts. Armed with pipe cleaners so snazzy that he’s become the envy of second-graders everywhere, Steve took to lining up the hoses in a way that was both functionally and aesthetically pleasing.
Did I mention to you that we made our first prototype of the PCV tap out of Playdoh? We decided not to use that method anymore, though, because we couldn’t get Steve to stop eating it.
Joking aside, here’s Steve, lining everything up to make sure the lines travel a route that is both attractive and unobstructed.
And here’s what we’ve come up with!
From a Different Angle
Due to threading variations in the head from car to car, the angled part of our tap will likely vary in orientation depending on how far into the threading our tap grounds out. We will be using two segments of hose where the CC line meets the blow-by tap. This will allow proper fitment on any car by enabling an L-shaped hose on the tap to point towards your CC line, no matter what the orientation of the tap is. Then, you can cut the CC line to exactly the perfect length you need to meet the L-shaped hose for your specific vehicle.
This photo depicts that setup, although to the untrained eye, it more closely resembles a group of caterpillars having a wild party. The arrows depict the range of possible orientations of the tap.
Once Steve bent the lines into shape, they would provide nice practical models featuring the angles necessary to properly route our hoses.
Coming Soon
You’ve got a good idea of how this kit is shaping up both for the ATS catch can and for the Camaro catch can. Today, we took a look at even more blow-by that we collected, and we also went into detail on Steve’s cool new way of laying out hoses. Next time, we’ll have some more pictures of all this work for you, as well as some more details on the Camaro’s mounting bracket.
Happy 2017, people! I hope you all had wonderful experiences throughout the holiday season and you welcomed in the New Year with a glass of something delicious. I know I did! Whatever you had, I’m sure you enjoyed it much more than your Camaro 2.0T enjoys drinking blow-by. So to begin the year on the right foot, we’re going to give you the opportunity to pick up a Mishimoto 2016+ Camaro 2.0T Catch Can kit.
In my last post, I gave all of the ATS owners a little love and showed you how we route catch can hoses with our loaner Cadillac. Today, it’s time to pivot back and take a look at the final setup as it will appear on the Camaro 2.0T. We’ve been working on a surprise addition to this design that you might want to check out.
Most everything that you read here will also apply to the ATS kit, but, as many have inferred, the Camaro project is a little bit further along in R&D than the Cadillac project (although not by THAT much). The Camaro kit is so close to ready, in fact, that it is now officially time to launch our pre-sale!
That’s right, people! You, your Camaro, and your Camaro’s LTG can all breathe a collective sigh of relief. Freedom from blow-by is in your future! The Mishimoto catch can kit is now available at our discounted price, so you can ensure that your Camaro breathes clean air like it should.
Surprise? I LOVE Surprises!
Some of you may have perked up in the first paragraph upon noticing the word “surprise” – that was the intent, so hopefully I’ve got you hooked. But let’s delve into what I meant by that.
You may recall from some of our earlier posts that the extent of the LTG’s PCV kitting from the factory comprises three different systems. The primary avenue for extracting blow-by, however, is accessed by tapping into a PCV valve within the valve cover. GM didn’t make it easy for us, but this is where our engineer’s ingenious innovation came into play. If you want a re-cap on how we engineered our way into the valve cover to get the blow-by out, circle back to my post on our patent-pending blow-by tap. Check out how much blow-by we’ve collected from that spot. Without a catch can, all of this goes back through your engine!

The mere fact that the lion’s share of oily nastiness travels through the internal system does not mean that the other systems are completely free of vaporized contaminants. To demonstrate that, let’s go back and take a look at the external systems to make sure we didn’t miss anything.
Circling Back for More Testing
In our exploratory testing, we discovered very little blow-by in the first external system we tested, and didn’t bother testing the other external system right away once we discovered the presence of the internal system. In fact, here is how I ended the second post:
“We hope to have more information for you on this third CCV system coming soon. Otherwise, we will likely be testing the second of the two external systems. Stay tuned for more on this unique project!”
We got so excited about Steve’s internal valve discovery and his ingenious solution, that bottles were popping, confetti was flying, and the office was merry with the same flavor of delight one might have experienced in Chicago this past November.
Just kidding. But we did give Steve a nice pat on the back. Though I may be hyperbolizing a bit (what else is new?), we did become genuinely excited about the blow-by tap, and the project became somewhat focused on addressing the internal system and developing that innovation into the best product it could be. It wasn’t until a bit later that we figured we’d double back to test that second external system. And boy, are we glad we did. Here’s why:
That, ladies and gentlemen, is blow-by. It isn’t a TON, but it isn’t nothing. At Mishimoto, blow-by is our sworn enemy. We think it really blows, and by golly, we’d love nothing more than to take this stuff and send it straight to hell. So with that attitude, there was no way we could see these results and not put the hammer down.
Doubling Down
So herein lies the surprise: we are offering a dual-can setup to address blow-by concerns in both the internal system as well as the external system. How’s THAT for thorough?
Now you might be wondering where on earth that second can is going to go. Well, we’ve figured out a way to mount the cans side-by-side in the front of the engine bay, near the expansion tank. As mentioned, the majority of the blow-by is in the internal system. So, we have decided to sell this as a modular system for those of you who would rather stick to a one-can setup.
You can buy the Mishimoto 2016+ Camaro 2.0T catch can kit with just the primary can (PCV-side) or you can buy it with both the primary and secondary (CCV-side) cans. If you opt for the former option, the included bracket features mounting points for the secondary can. So, if you want to add that on later, you can. That’s right, we’ll be selling the secondary kit by itself as well.
For those of you with Cadillacs, you will also have the option to supplement the primary can with a secondary can, although both cans will be mounted in separate locations. More on that in a future post – right now, it’s the Camaro’s turn in the spotlight!
Check out some shots of the final Camaro 2.0T bracket and hose setup.
WE GET AROUND – CATCH CAN R&D, PART 6: CADILLAC FIELD TRIP
For those of you just catching up with us now (I crack myself up), this ATS kit is largely the same as our Camaro 2.0T catch can kit, which is now on pre-sale—don’t worry, the ATS pre-sale is not far behind!
However, to properly fit the Caddy, we needed to design a bespoke set of ATS-specific brackets and hoses.
You may have seen an earlier post detailing the ultra-high-tech way we laid out the initial designs, and that method proved to be an effective one. The layout we determined through those methods was mapped onto a 3D-drawing, and we used that drawing to cook up a proper prototype with aluminum brackets and silicone hoses. All that was left was to test fit our setup on an ATS.
Testing the Cadillac… at the Porsche Dealership?
For the test fit, Steve (our engineer), Rob (project manager), and I were sent out on a bit of a field trip. The generous customer who allowed us to use his ATS as a guinea pig provided one caveat to the agreement: we could use the car, but he couldn’t leave his work or take any time away. So, we were welcome to use his car for testing, but we had to travel to his workplace and perform the test fitment in his parking lot. This just happened to be at a local Porsche dealership, so he really had to twist our arms.

So, off to Porsche we went. This worked out quite well, because it also gave us the chance to kill two birds with one stone and take measurements for the upcoming Mishimoto 2013-2015 Porsche 918 Spyder catch can kit! I’m just kidding, of course. We certainly did not take measurements on that car, but only because the dealer had JUST sold their only one for a cool $1.2M. So, we’re still looking for a test vehicle – reach out if you know anyone!
All joking aside, we had a very successful test fit. First, we began by installing the PCV-side system – Steve was very excited to install his patent-pending blow-by tap (above).

Final Fitment
We continued with the CCV side, and took measurements throughout the process to make a note of any changes that might be necessary. Barring a few small things, this fitment is pretty spot on. One of the adjustments we will be making is to slightly lengthen parts of the CCV side hose to extend the section in front of the engine so it fits more snugly along the existing lines that travel across the bottom of the plastic cover.
It looks damn good, too – what do you all think?
