Compact Baffled Oil Catch Can

"If it ain't broke, don't fix it." This colloquialism is a phrase we've all heard before. It translates to, "If it's still working, why put any effort into improving it?" But that doesn't sit well with us here at Mishimoto, especially when referring to keeping your engine running at peak efficiency. So with that in mind, it's time our tried-and-true compact catch can got a refresh, and we're stoked to show it off. 

Since 2014, our compact catch can has been filtering out harmful blow-by from CCV systems around the world in its universal form and has starred in tons of direct-fit applications. It has a long service history, but we wanted to evolve it into something even more effective. 

The old and new cans look just about the same from the outside, and that was on purpose. We prefer to keep a sleek and compact look that fits in with just about every engine bay, so we only made minor updates to the styling. If you take a peek at the top side of the can lid, you'll notice that we added

The project is complete! We are very pleased with the outcome, and we expect a ton of positive feedback on this product. In fact, three or four of our employees have already reserved units for their personal vehicles. Speaking of " I should pick up one for my NB Miata!

The production quality catch can is now prepared for your viewing pleasure. Check it out below, starting with the base of the can.

The CNC-machined components keep rolling in! Our last prototype has been constructed and is now ready for our final evaluation before beginning mass production of these units. This prototype is a raw aluminum version; our final version will feature a black anodized finish.

The first completed component is the base/can portion of the product. This is a CNC-machined piece with internal threading on the upper portion, a port on the bottom for a drain or valve, and knurling at the bottom for ease of removal.

In the image above, you can see that we did some road testing with this catch can, using one of our employee's vehicles, to ensure that it was operating as we designed it. Everything checked out, and we caught quite a bit of oil even during short periods of driving!

Time to fabricate/prototype our awesome catch can design! We would be using our in-house fabrication equipment and our 3D printer to develop a plastic and metal prototype.

Prototype Fabrication

We began by fabricating the base of the can from aluminum. Dan set to work cutting, welding, and polishing the base you see below.

Notice that the base of this can does not feature a drain. We did not incorporate one into our initial fabricated component, but we do plan to add a drain port on the base for those who wish to install a valve or drain line to the oil pan. No details were left untouched during development.

Next, we printed a unit and coated the inside for testing. The 3D printed material is somewhat porous. We use an internal coating that properly seals the components and provides a surface with properties similar to our

So we asked ourselves, what makes a catch can appealing to the masses? In a market swamped with extremely low-priced options, a new product could easily get lost in the mix of products already available. Our team began sifting through forums and asking our contacts at local shops to see exactly what they wanted from a catch can. We also reviewed our current line of products, to see if we could develop a new design that would fit within our current offerings.

An efficient catch-can setup is not generally perceived as a product that will impact engine performance or power. This is not true at all! A catch can will make a significant impact on the cleanliness of the intake components, including the charge air cooler (CAC) system, as well as reduce detonation within the combustion chamber.
