Mishimoto is excited to announce that we're developing a direct-fit catch can kit for the 2011-2016 and 2017+ 6.7L Powerstroke! Check out our review of the stock CCV system below and let us know what you think!
Dirty Work – Oil Catch Can Kit R&D, Part 1: Stock Review
The most rewarding work is hard work. But hard work is often dirty work. If you’re a car or truck enthusiast, you know the feeling of accomplishment you get from the hard work of fixing or modifying your vehicle. You also know the struggle of trying to scrub away the grime from under your fingernails afterwards.
Few people know the reward of hard work more than those who work on diesel trucks or those who use them every day to make a living. You’d be hard-pressed to find a construction site, landscaping job, or farm without a diesel truck somewhere nearby. If the owner of that truck is really serious about hard work, it’s likely a Ford Powerstroke. Ford’s latest addition to the Powerstroke lineage, the 6.7L, has been serving hard-working Americans since 2011. The 6.7L Powerstroke is one of the best engines ever fitted to Ford’s Super Duty trucks, but it’s not without its flaws.
If you’ve ever pulled an intercooler pipe off a 6.7L Powerstroke, you know just how much blow-by makes its way into the intake and turbo system. This blow-by is full of carbon, oil, fuel, water, and other byproducts of combustion that have made their way past the piston rings and into the crankcase.
Blow-by gushing from the CCV system of our 2011 6.7L Powerstroke
To keep the crankcase from becoming over-pressurized, the 6.7L vents the blow-by into the turbo inlet to be reburned with the rest of the intake air. But, before it gets back to the cylinder to be burned, the blow-by coats the turbo compressor wheel and hot-side intercooler pipe. Then, it fills the tiny channels in the intercooler and covers the cold-side intercooler pipe before spreading itself all over the intake. This blow-by eventually builds up to the point that it affects the engine’s exhaust gas recirculation (EGR) system, lowers the intercooler’s efficiency, and coats the intake valves in carbon; all of which reduces the amount of power produced from your 6.7L Powerstroke.
