Hello Explorer Forums!
Nick here from Mishimoto! I just wast wanted to kick off this thread to let you guys know that we've been working on a direct-fit catch can kit for the 3.0T EB under the hood of these ST's. Make sure that you head over to our blog to check out the full scoop on our R&D process!
No matter the vehicle segment, however, any and all internal combustion engines suffer from the same nasty side-effect – blow-by, Explorer ST included. To put it simply, blow-by is when oil and fuel droplets are mixed in with recycled crankcase pressure. Some combustion gasses make their way past the piston rings during the power stroke and pressurize the crankcase. In the olden days, this pressure was relieved by venting to the atmosphere, which spewed harmful emissions, not to mention slick oil on the roads. Now, though, this pressure is routed and recycled through the intake via the positive crankcase ventilation (PCV) system, fuel, and oil, and all. The blow-by mixture will collect on the engine’s intake components, specifically the intake valves, resulting in sticky carbon buildup, which detracts from the sport part of your sport utility vehicle. For a more in-depth look at blow-by, make sure you check out our full tech article: Blow-By 101: What is Blow-By and How to Keep it from Ruining your Engine.
The easiest means of mitigating the issue of blow-by is with a catch can. Our catch cans mount in line with the PCV system and separate the blow-by from the air running through the system. The sudden addition of volume, combined with an internal baffle, allows the fuel and oil vapors to condense and collect in the bottom of the can rather than on the EcoBoost’s intake valves. For a last line of defense, we also incorporate a bronze filter in our cans that trap any rogue droplets still looking to stick on the intake components.
Feel free to reach out with any questions that you might have, and also make sure that you stay tuned for more info on our catch can, AND more upcoming Explorer ST R&D.
Thanks!
