Back for Pasture – 2021+ Ford Bronco 2.7L Baffled Oil Catch Can R&D, Part 2 – PCV-Side Concept and Design

The Bronco is back, which is basically old news at this point. However, as the hum of excitement subsides for this legend’s return, the buzz is now shifting to the endless possibilities to customize and accessorize this off-roading machine. Naturally, Ford anticipated the owner’s needs to personalize their Broncos, launching the line with a plethora of accessories to appear more adventurous and act the part. However, missing from the catalog was a means of adding a layer of protection against the onslaught of blow-by on the intake tract. Not to worry, though, since we here at Mishimoto wanted to ensure that you had options in that department. 

Some of you might be asking what blow-by is and what it has to do with your intake system, while keen Bronco enthusiasts are also questioning the need for a catch can system on 2.7L EcoBoost’s dual-injection system. Well, we’re glad you asked! So, make sure you head back to our first post for all the answers!  

Now that you’re caught up, you’ll know that we’re also working on our full dual can setup, but we know that some of you might be more interested in more focused protection. Since the PCV system is the main culprit for blow-by, our engineer, Ye, developed a new bracket specifically for a single can system. 

Our PCV-side bracket still utilizes one of the same threaded pegs that protrude from the firewall, plus piggybacking off of the mounting points for the ECU resulting in a sturdy perch for our compact catch can at the rear of the engine bay. This location reduces our system’s footprint and conveniently places the can near the 2.7L’s PCV ports.

Like our complete system, this PCV-side kit also requires a preliminary test of 1000 miles. In the same sense, this kit also needs some final refinement while our Bronco hits the road. No matter if you opt for full or focused protection for your 2.7L EcoBoost, we’ll have the right option for you. Make sure you stay tuned for our testing results and the first look at our final design. 

Thanks for Reading!
