  1. Design and Fabrication - Catch Can R&D, Part 1

    Design and Fabrication - Catch Can R&D, Part 1

    We have been searching long and hard to get our hands on the new Honda Civic, and the search is now over! A brand new 2016+ Honda Civic equipped with the 1.5L Turbo engine has finally reached our R&D facility, thanks to a very generous owner. One of our first targeted projects is an oil catch can. There are many benefits to equipping a vehicle with a catch can. Modern fuel injection is accomplished by either port or direct injection, the latter used by this Civic. Let's briefly talk about the differences between the two.

    Port vs. Direct Injection

    With port injection, the fuel injectors are situated right inside the intake manifold, producing a fuel stream to mix with the air. That air/fuel mixture is shot straight into the combustion chamber through a valve. As the fuel passes through the valve area, much of the debris gets cleaned off - because as we all know, gasoline is an excellent solvent.

    Direct injection, however, is the more common

    After completing the fabrication of our brackets for this kit and assembling the STI-specific lines, it was time to tackle the WRX. As you may be aware, the stock CCV lines are slightly different on the WRX, which necessitates a separate set of WRX-specific catch can lines.

    The Test Subject

    After reaching out to local contacts, we found a willing vehicle donor just one state away. We have borrowed this particular vehicle on several occasions for a variety of test fittings. A big "thank you" to the owner for lending his vehicle and his time for the sake of awesome new product development!

  3. Blow-By Verified - Oil Catch Can R&D, Part 1: That's A Lot of Oil

    Blow-By Verified - Oil Catch Can R&D, Part 1: That's A Lot of Oil

    What do carbon-deposit caked valves, decreased fuel economy, oily intake tracts and inefficient combustion all have in common? The resulting effects of engine oil blow-by. During combustion, the top side of the piston forces combusted gasses, with remnants of fuel and oil past the piston rings, and into the crankcase. This would force the crankcase to become pressurized without some sort of relief, so the content of what enters the crankcase exits the system through a positive crankcase ventilation (PCV) system and gets recycled through the engine via the intake tract.

    Dirty Work - Oil Catch Can Kit R&D, Part 3: Testing

    The last steps of any project are the hardest to get through. The excitement of enjoying the results of your hard work can often get in the way of doing the job right. But hard work without patience often leads to more work.

    For us, the last steps of our 2011-2016 and 2017+ catch cans were also the most technically demanding. In our last post, we took measurements of both trucks' filter boxes and engines with our 3D scanner, then designed and 3D printed adapters to fit between the engine and the filter box. These adapters will give us a way to divert blow-by from the valve cover into our catch can, then back through the filter box and into the engine.

    For a Flawless Return - Direct-Fit Catch Can R&D, Part 2 - Design and Test Results

    BAFFLED OIL CATCH CAN KIT, CCV SIDE, FITS TOYOTA GR SUPRA 3.0L 2020+

    Just about every major launch these days is complemented by some unforeseen bug in the system. It's just the way of the world, and manufacturers are quick to solve these small hiccups with a recall or a software update. Some bugs aren't easily remedied with a code revision or swapping for updated parts. For many vehicles, including your A90 Supra, blow-by will be an issue no matter the measures taken by Toyota and BMW to prevent it. When it comes to protecting your intake components, the solution requires a hardware upgrade, and we have that hardware.

    Even with the help of some technical documents from BMW, determining which line to tap for our catch can requires some hands-on science.

    Free to Roam - Catch Can R&D, Part 3: Test Results

    Our 2019+ Ford Ranger has been roaming the streets of Delaware, Pennsylvania, and New Jersey for the past 1,000 miles testing our direct-fit oil catch can. In this post, we'll be emptying the catch can to see what, if anything, it caught. If all goes to plan, we'll also be kicking off the pre-sale so you can protect your Ranger from blow-by, without blowing your budget.

    In our last post, we looked at the stock crankcase ventilation system on the 2019+ Ranger's 2.3L EcoBoost. We explained that the system was divided into two parts: the CCV side and the PCV side. The CCV side is active when the turbocharger is pressurizing the intake manifold, while the PCV side is active when cruising or idling. The CCV side also incorporates a pressure sensor that we've fought with

  7. Keep your intake clean - Oil Catch Can R&D, Part 1: Introduction and Fabrication

    Keep your intake clean - Oil Catch Can R&D, Part 1: Introduction and Fabrication

    So far this Fiesta ST has had an interesting life with Mishimoto. The very same day that we drove it off the lot, it was rolled into our development facility and fitted for its first modification: a prototype baffled catch can kit. Why did we chose to begin with this? From our experience with other EcoBoost equipped vehicles, we know how prone these engines are to blow-by and carbon buildup. If you want to read more in depth about the benefits of a catch can, check out our complete write up on Blow-By 101. Installing a catch can right away allows us to protect the engine of our new development vehicle and gives us more time for data collection as we work on developing additional Fiesta ST parts. Last, but certainly not least of all, we asked for your feedback and received an overwhelming response to create a Fiesta ST catch can (yes we do listen to you!).

    Prototype Fitment - Catch Can R&D, Part 2

    We are moving fast with this project! We have now talked about the differences and significance between two types of fuel injection, evaluated the stock system and began designing a bracket with our neat waterjet. We have also dived into the specifics of how our catch can works. Now, we have a working prototype that we have mounted onto our loaner Civic.

    We decided to go ahead and use the open space right behind passenger side of the motor that would conveniently place our catch can around the PCV ports. This will lighten any complexities in the hose routing.

    Back From Pasture - 2021+ Ford Bronco 2.7L Baffled Oil Catch Can R&D, Part 4 - Full System Production Sample

    Advances in technology worked wonders for the internal combustion engine. With every new vehicle launched, there's a list of advancements to these controlled-explosion contraptions to harness maximum power and efficiency while keeping emissions in check. It's no secret that Ford doused their reinvented Bronco in these same innovations, but even this new-school hardware still falls victim to old-school by-products, like blow-by.

    No matter the installed innovations, blow-by still remains the age-old nemesis of any engine's top-end components. The mix of fuel and oil vapors galvanize into stubborn carbon buildup, robbing the 2.7L of the power and efficiency the Ford engineers painstakingly worked into this engine. Yes, this engine utilizes a dual-injection system that will mitigate carbon buildup, but even port-injection vehicles suffer the same symptoms of unfiltered blow-by over time. So, even with factory-installed countermeasures, a catch can setup is still one of the best means of

    Clean Camaro - Catch Can R&D, Part 1: Prototype Design

    Success in engineering is rarely the result of one attempt. Our products go through revision after revision before they ever see the light of day (or darkness of your engine bay). This goes for complex products, like oil cooler systems and intercoolers, to seemingly simple catch can brackets. Our engineers must consider every situation that could occur in a vehicle, then design our products to handle them. The development process for our 5th Gen Camaro SS direct-fit oil catch can is no exception to that rule.

    Success is also rarely the product of one person's efforts. Teamwork plays a major role in every product here at Mishimoto. From conception to release, our projects are touched by just about every Mishimoto employee. When it comes to designing and developing a catch can kit, more ideas create a better product. That's why our engineer, Jason, brought in one of our draftsmen, Josh, to help with this kit's design.

    This wasn't Josh's first time designing a product, however.
